Description
Wegovy Weight Loss Injection is an approved medication designed to aid in chronic weight management for adults with obesity or those who are overweight with weight-related health conditions. Wegovy works by mimicking the action of the hormone GLP-1 (glucagon-like peptide-1), which helps regulate appetite and food intake by targeting areas in the brain responsible for hunger control.
Wegovy is available as a pre-filled injection pen that is self-administered once weekly, making it a convenient option for those looking to manage their weight alongside a reduced-calorie diet and increased physical activity.

Comprehensive Information
Wegovy (Semaglutide) – Weekly Weight Loss Injection for Adults
Wegovy is a prescription-only weight loss injection available in the UK for private patients. It contains semaglutide, a medication that can help adults with obesity or overweight conditions lose weight by reducing appetite. Wegovy is used alongside a reduced-calorie diet and increased physical activity to support significant, sustainable weight lossmedicines.org.uk. In this comprehensive guide, we explain what Wegovy is, how it works, who it’s for, how to use it, expected results, side effects, and important safety information for UK patients considering this treatment.
What Is Wegovy and What Is It Used For?
Wegovy is a once-weekly injectable medicine specifically licensed for weight management in adults. It’s not a diet pill or a quick fix, but a medical treatment for people who meet certain criteria for obesity. Wegovy should be used as part of a weight loss plan that includes healthy eating and exercise, to help you lose weight and keep it offmedicines.org.uk. The active ingredient in Wegovy is semaglutide, which is the same ingredient found in some diabetes medications (like Ozempic) but Wegovy is formulated and approved for weight loss rather than for blood sugar control.
Uses of Wegovy: Wegovy is indicated for adults who need to lose weight for health reasons. Specifically, you may be eligible for Wegovy if you have:
-
A body mass index (BMI) of 30 or above (classified as obese)medicines.org.uk.
-
A BMI of 27 or above (overweight) with at least one weight-related health condition such as type 2 diabetes, high blood pressure, high cholesterol, or obstructive sleep apnoeamedicines.org.uk.
BMI is a measure of weight relative to height, and a BMI ≥30 is considered obese. In other words, Wegovy is intended for people who are significantly overweight or obese, especially if excess weight is affecting their health. By helping reduce appetite and calorie intake, Wegovy can assist such individuals in losing weight when diet and exercise alone have not been enough. It is available privately in the UK on a doctor’s prescription and is not part of standard NHS prescriptions for general use (NHS access is currently limited to specialist weight management services). For private patients, Wegovy offers a new option to achieve weight loss under medical supervision.
How Does Wegovy Work? (The GLP-1 Mechanism)
Wegovy contains semaglutide, which belongs to a class of medicines called GLP-1 receptor agonists. GLP-1 (glucagon-like peptide-1) is a natural hormone your body releases after eating, which helps regulate appetite and digestion. Wegovy mimics the action of GLP-1 in your bodymedicines.org.ukema.europa.eu. By activating GLP-1 receptors in the brain, Wegovy helps you feel fuller and less hungry, so you’re satisfied with smaller portions and have fewer cravingsmedicines.org.uk. This leads to eating less and, over time, weight loss.
In addition to curbing appetite, semaglutide slows stomach emptying, which means food stays in your stomach a bit longer, helping you feel full for extended periods. It may also influence blood sugar regulation (which is why lower doses are used in diabetes treatment), but the primary effect for weight loss is on appetite and calorie intake. Essentially, Wegovy acts on the areas of the brain that control hunger and fullnessmedicines.org.uk. By reducing daily calorie consumption, it creates the conditions for steady weight loss when combined with lifestyle changes.
Patients often notice that after starting Wegovy, they get full faster when eating and are less inclined to snack or overeat. This pharmacological support can make it easier to adhere to a calorie-controlled diet. However, it’s important to maintain healthy eating and exercise habits while on Wegovy to achieve the best results. Wegovy is not a stimulant or traditional appetite suppressant; it works hormonally, which tends to result in a more gradual, natural-feeling reduction in appetite rather than a jolt.
Wegovy vs. Ozempic – What’s the Difference?
You may have heard of Ozempic, another semaglutide injection. It’s true that Wegovy and Ozempic contain the same active ingredient (semaglutide), but they are licensed for different purposes and used in different doses:
-
Purpose: Ozempic is licensed to treat type 2 diabetes (to improve blood sugar control), though patients on Ozempic often lose some weight as a side effect. Wegovy, on the other hand, is specifically licensed for weight loss in people with obesity or overweight – it is not a diabetes medicationgoodrx.comgoodrx.com. If you have type 2 diabetes and need weight management, your doctor might still consider Wegovy as part of your weight loss plan, but it’s not meant to replace diabetes medicationsgoodrx.com. Conversely, Ozempic is not officially approved as a weight-loss treatment in the UK (any weight loss use of Ozempic is “off-label”).
-
Dosage: Wegovy is administered at a higher target dose than Ozempic for greater weight loss effect. Wegovy’s maintenance dose is 2.4 mg once weekly, whereas Ozempic’s usual maintenance dose for diabetes is 0.5 mg to 1 mg once weekly (Ozempic can be increased up to 2 mg weekly for blood sugar control, but that’s still lower than Wegovy’s dose)goodrx.comdrugs.com. The higher dose in Wegovy is what helps produce more substantial weight loss. Wegovy pens come in five dose strengths – 0.25 mg, 0.5 mg, 1 mg, 1.7 mg, and 2.4 mg – used during the dose-escalation schedule (more on that below). Ozempic pens typically deliver up to 1 mg (or 2 mg in new versions) per dose.
-
Availability and Branding: Wegovy is a single-use pre-filled pen for weight loss; you use one pre-filled pen for each weekly injection (then dispose of it). Ozempic pens are multi-dose pens that contain several doses – you attach a needle and dial your dose each time from the same pengoodrx.com. The convenience of Wegovy’s single-dose pens is that you don’t need to measure the dose – each pen is preset to deliver the exact dose for that week. (Each Wegovy pen has a colored label corresponding to its dose strength, for example, 0.25 mg pens have a green label, 2.4 mg pens have a black label, etc., to help avoid confusion.)
-
Use Together: You should not use Wegovy and Ozempic at the same time. Because they contain the same medication, using them together could lead to an overdose of semaglutide. If you are switching from Ozempic (for diabetes) to Wegovy (for weight loss), or vice versa, this should be done under medical guidance with appropriate timing to avoid overlap.
In summary, Wegovy is essentially semaglutide adapted for weight management, whereas Ozempic is for diabetes management. Wegovy’s higher dose leads to greater appetite suppression and weight loss in eligible patientsuchealth.org. If weight loss is your primary goal and you meet the criteria, Wegovy is likely the more appropriate choice. Ozempic should be reserved for its intended use (diabetes) unless a healthcare professional advises otherwise. Always follow your doctor’s guidance on which medication is right for you.
Who Can Use Wegovy? (Eligibility and Suitability)
Wegovy is intended for adults aged 18 and over who need medical support to lose weight. The general eligibility criteria for Wegovy are based on BMI (Body Mass Index) and health status:
-
BMI ≥ 30 (Obesity): Adults with a BMI of 30 or higher can be considered for Wegovymedicines.org.uk. This typically includes people who are clinically obese. For example, if you are 5’6” (1.68 m) tall and weigh 13 stone 3 lb (84 kg) or more, your BMI would be around 30 or above. Wegovy can help such individuals lose weight when diet and exercise alone have not succeeded.
-
BMI 27 to 29.9 with Weight-Related Health Conditions: Adults with a BMI in the 27–29.9 range (overweight, but not quite 30) may also qualify if they have at least one weight-related health problemmedicines.org.uk. These conditions include common issues like type 2 diabetes, high blood pressure, high cholesterol, or obstructive sleep apnoea, among others. The presence of these conditions means losing weight is particularly important for health, and Wegovy may be considered to help reduce those risks.
-
Must be part of an overall weight loss plan: Wegovy is most suitable for individuals who are committed to making lifestyle changes as well. It should be used alongside a calorie-reduced diet and regular physical activitymedicines.org.uk. If you’re considering Wegovy, you should be ready to adjust your eating habits and incorporate exercise, as the medication works best in combination with these changes.
-
Tried other weight loss methods: Wegovy is usually prescribed for patients who have tried to lose weight through diet, exercise, or other interventions and have not achieved sufficient weight loss. It’s often used when other approaches alone have not been effective.
-
Private Prescription Context: In the UK, Wegovy is currently available via private prescription (for example, through private clinics or pharmacies with an online doctor service). You will typically need a consultation to confirm you meet the criteria and it’s safe for you. NHS prescribing of Wegovy is restricted to specialist weight management services and under stricter criteria (for instance, in some cases BMI ≥35 or ≥30 with certain co-morbidities, and usually with a 2-year usage cap). For private use, the licensed criteria remain BMI ≥30, or ≥27 with a related condition, as above. Always ensure the prescribing service assesses your health thoroughly – you may need to provide your BMI and health information.
-
Age: Wegovy is licensed for adults. (It has also been studied in adolescents aged 12–17 with severe obesity, but for the purposes of a pharmacy service, it’s generally not provided to under-18s unless under specialist supervision.) If you are over 65, Wegovy can still be used, but your doctor will consider your overall health. There isn’t an upper age cut-off in the license, but since older adults may have more medical issues, a careful medical assessment is required.
In summary, Wegovy is for adults carrying a lot of excess weight, especially if it’s impacting their health. It is not a casual weight-loss aid for those who are only slightly overweight or aiming for cosmetic weight loss. A healthcare professional will determine if you meet the criteria and if Wegovy is appropriate for you. If you do not meet the BMI or health criteria, other weight management strategies or medications might be recommended instead.
Who Should NOT Use Wegovy? (Cautions and Contraindications)
While Wegovy can be very effective for eligible patients, it’s not suitable for everyone. You should not use Wegovy if any of the following apply:
-
Allergy to Semaglutide or Ingredients: Do not use Wegovy if you are allergic to semaglutide or any of the other ingredients in the formulationmedicines.org.uk. An allergic reaction could be serious. Tell your doctor if you’ve had any unusual reactions to similar medications (such as other GLP-1 injections like liraglutide).
-
Pregnancy: Do not use Wegovy if you are pregnant, planning to become pregnant, or suspect you might be pregnant. Weight loss medications are not recommended during pregnancy, and it’s not known if semaglutide could affect an unborn baby. You should use effective contraception while on Wegovy if you are of childbearing potentialmedicines.org.uk. If you plan to try for a baby, you’ll be advised to stop Wegovy at least two months before attempting to conceivemedicines.org.uk. If you become pregnant on Wegovy, inform your doctor immediately – the treatment will need to be stopped.
-
Breastfeeding: You should not use this medicine if you are breastfeedingmedicines.org.uk. It’s not known whether semaglutide passes into breast milk, and because it could affect the baby’s feeding (by reducing your appetite and possibly the caloric content of milk), it’s advised to avoid it.
-
Personal or Family History of Certain Thyroid Tumors: Wegovy (and other GLP-1 medications) carry a warning about medullary thyroid carcinoma (a rare type of thyroid cancer) and MEN2 (Multiple Endocrine Neoplasia syndrome type 2). Do not use Wegovy if you or a family member have ever had MTC or MEN2. This is a precaution because semaglutide caused thyroid tumors in rodent studies, though it’s not proven in humansapclabs.co.uk. As a safety measure, regulators advise against using it in people with that history. Also, if you notice any neck swelling, hoarseness, trouble swallowing, or a lump in your neck while on Wegovy, report it to your doctor, as these could be warning signs (although these occurrences are very rare).
-
Severe Digestive Problems: Use caution or avoid Wegovy if you have severe gastrointestinal (GI) issues, such as gastroparesis (slow stomach emptying) or severe reflux, unless your doctor says it’s okay. Wegovy’s mechanism slows stomach emptying further, which might worsen certain GI conditions.
-
Pancreatitis History: If you have a history of pancreatitis (inflammation of the pancreas), inform your doctor. While Wegovy can be used in many people with past pancreatitis, GLP-1 drugs have been associated with rare cases of pancreatitis. Your doctor may decide if the benefits outweigh the risks. If you have severe, unexplained stomach pain (especially if it radiates to your back) while on Wegovy, seek medical attention as that could be a sign of acute pancreatitismedicines.org.uk.
-
Diabetes on Insulin or Sulfonylureas: If you have diabetes and are on medications like insulin or sulfonylurea tablets, Wegovy is not a substitute for insulinmedicines.org.uk. Wegovy can be used by people with type 2 diabetes who need to lose weight, but careful monitoring is needed. Combining Wegovy with insulin or sulfonylureas can increase the risk of low blood sugar (hypoglycaemia)medicines.org.uk. Your doctor may adjust your other diabetes medications when starting Wegovy. Do not use Wegovy alongside other GLP-1 agonist medications (for example, do not use it with Ozempic, Saxenda, Trulicity, Byetta, etc. which are similar drugs)medicines.org.uk. Also, do not mix Wegovy and insulin in the same injection – they must be injected separately if prescribed together.
-
Children: Wegovy is not recommended for children under 12, and in practice, not prescribed for those under 18 in general weight management through pharmaciesmedicines.org.uk. The safety and efficacy for younger children are not established. Adolescents 12–17 with severe obesity might be treated by specialists, but this would not be via a routine pharmacy service.
-
Liver and Kidney Disease: If you have severe liver or kidney impairment, your doctor will approach Wegovy with caution. There isn’t a strict contraindication, but vomiting or nausea from Wegovy could affect kidney function (due to dehydration)medicines.org.uk, and there’s limited data in severe organ impairment. Your doctor may start at a lower dose or monitor you more closely. If you’re on dialysis, Wegovy is not recommended.
-
Gallbladder Disease: Significant rapid weight loss, whether from diet or medications like Wegovy, can increase the risk of gallstones or gallbladder disease. If you have a history of gallstones or had your gallbladder removed, let your doctor know. Wegovy isn’t outright contraindicated, but be aware of symptoms like severe right-sided abdominal pain or shoulder pain (which could indicate gallstones). Rarer cases of gallbladder issues have been reported with Wegovy use due to rapid weight reductionbhf.org.uk.
-
Mental Health: If you have a history of depression or suicidal thoughts, mention this to your prescriber. A small number of people report mood changes when losing weight rapidly. It’s not a listed contraindication, but any new or worsening depression should be monitored. Seek help if you experience significant mood changes.
In summary, do not use Wegovy if you’re pregnant or breastfeeding, have certain rare hereditary cancer syndromes, or are allergic to it. Use it with caution (and full disclosure to your doctor) if you have other significant health issues like pancreatitis history, severe gut problems, or if you’re on other medications that might interact. Always discuss your full medical history with the prescribing doctor or pharmacist so they can determine if Wegovy is safe for you. If you’re not sure whether something applies, ask – they will help assess the risks and benefits in your situation.
Expected Weight Loss Results with Wegovy (Clinical Trial Outcomes)
Wegovy has shown very promising results in clinical trials, which is why it’s considered a breakthrough in obesity treatment. However, individual results will vary. It’s important to have realistic expectations: Wegovy is not an instant fix, but over several months it can lead to substantial weight loss when combined with lifestyle changes.
Clinical trial results: In the major trials (known as the STEP trials) for Wegovy:
-
Patients on Wegovy lost significantly more weight than those on placebo. In one large 68-week trial, adults with obesity lost about 15% of their body weight on average with Wegovy, compared to about 2% for those who took a placeboema.europa.eu. To put this into perspective, if you weighed 100 kg (15 stone 10 lb) at the start, 15% weight loss is about 15 kg (around 2 st 5 lb) lost on average. Some people lost much more, some less – that’s an average figure.
-
A high proportion of patients achieved meaningful weight loss. In that trial, 84% of people on Wegovy lost at least 5% of their starting weight, versus 31% on placeboema.europa.eu. Losing 5% or more of body weight is a common benchmark for improving health markers (blood sugar, blood pressure, etc.), so this is a significant outcome. Moreover, about two-thirds of those on Wegovy lost 10% or more, and many achieved 15% or even greater weight loss.
-
Another trial showed an average weight reduction of around 16% after 68 weeks on Wegovy, when combined with lifestyle counseling, compared to about 6% in the placebo groupema.europa.eu. This suggests that adding Wegovy to diet and exercise roughly triples the amount of weight loss versus lifestyle changes alone in many cases.
-
In a study focusing on individuals with type 2 diabetes (who often lose weight a bit more slowly), Wegovy led to about 10% average body weight loss in 68 weeks, compared to 3% with placeboema.europa.euema.europa.eu. People with diabetes tend to lose a bit less weight on Wegovy than those without diabetes, but 10% is still clinically significant for that group.
-
Sustained use is important: One trial (STEP 4) looked at what happens if Wegovy is stopped. Patients took Wegovy for 20 weeks, then some were switched to placebo. Those who continued Wegovy kept losing weight (an additional ~8% over the next 48 weeks), while those who stopped the medication regained about 7% of their body weightema.europa.eu. This indicates that continuing the treatment is needed to maintain the weight loss – if you stop, appetite will likely return to normal and weight can creep back up. In other words, Wegovy is most effective as a long-term therapy (often a course of 1–2 years or more, depending on your doctor’s plan) rather than a short-term diet aid.
-
Timeframe of weight loss: Weight loss with Wegovy is gradual but steady. In the first month or two, as you titrate up the dose, you might lose a few percent of your weight. By around 3 months in, many patients see a noticeable difference. By 5 months (20 weeks), when you reach the full dose, one trial noted an average of about 10% weight loss already achievedgoodrx.comgoodrx.com. Weight loss usually continues beyond that – by 1 year (approximately 68 weeks), that’s when the ~15% average loss is observed. Some patients in trials lost 20% or more of their body weight by the end of the first year on Wegovy.
-
Health benefits: Beyond the numbers on the scale, losing weight with Wegovy can lead to improvements in blood pressure, blood sugar, and cholesterol levels. In fact, in people with pre-diabetes or insulin resistance, weight loss often reduces the risk of developing type 2 diabetes. Wegovy has also been studied for cardiovascular benefits: one recent approval (in mid-2024) was for using semaglutide to reduce the risk of heart attack and stroke in certain overweight patients with heart diseasebhf.org.uk. So weight loss from Wegovy can translate into meaningful health improvements like better mobility, improved blood sugar control (even if you’re not diabetic), less strain on joints, and improved self-esteem.
Remember, individual results vary. Some people might lose 20%+ of their weight, while others might lose 5-10%. Factors like adherence to diet and exercise, genetic differences, and how long you stay on the medication all play a role. Wegovy is most effective when you fully engage with a healthier lifestyle while taking the injections. It’s not magic, but it does make it easier for many people to eat less, feel satisfied, and lose weight in a controlled manner.
Your doctor or pharmacist will typically monitor your progress. A common practice is to evaluate weight loss after a set period (for example, after 3 or 6 months on the full dose). If you’ve lost a certain percentage of your body weight and are tolerating the medication well, treatment can continue. (For instance, guidelines often say if you haven’t lost at least 5% of your weight after 3–6 months on the max dose, they’ll reassess whether to continue Wegovy.) In clinical practice, however, many patients do see benefits by that time.
Bottom line: Many patients using Wegovy, along with diet and exercise, achieve significant weight loss that can improve their health. It’s one of the most effective weight loss medications available, with trial data showing average losses around 15% of body weight over a year or soema.europa.eu. Keep in mind that continued use is needed to maintain the benefits, and lifestyle efforts remain key to reaching and sustaining your goals.
How to Use Wegovy – Injection Instructions and Tips
Wegovy is administered as a once-weekly injection under the skin (a subcutaneous injection). Although the thought of injections may sound daunting, the Wegovy pen is designed to be user-friendly for patients to self-inject. The needle is very thin and short, and most people find the injections are manageable – often virtually painless or just a slight pinch.
Here’s an overview of how to use Wegovy injections properly:
-
Injection Sites: Wegovy should be injected into the fatty layer just under the skin (not into muscle or veins)medicines.org.uk. Recommended injection sites include the abdomen (stomach area), the front of your thighs, or the upper arm (if someone else is giving you the shot, they can use the back of the upper arm)medicines.org.uk. Some patients also use the upper outer buttocks. Pick a site that is comfortable and has some fatty tissue. Rotate your injection sites each week – for example, alternate between left and right sides, or between abdomen and thigh – to reduce the risk of irritation or skin lumps at any one site.
-
Preparation: Wegovy comes in a pre-filled pen that is pre-set to deliver a specific dose. Each pen is single-use and comes with its needle already attached and covered. Before injecting, check the pen’s label to make sure you have the correct dose pen for the week (especially important during the first 16 weeks when the dose changes). Also check the solution visible in the pen’s window – it should be clear and colorless. Do not use the pen if the solution looks cloudy, discoloured, or has particles. Wash your hands and clean the injection site with an alcohol swab (let it dry) if recommended.
-
Injecting: Remove the pen cap just before injection (this will expose the needle – although it may still be not visible in some pen designs as it’s inside a guard). Press the pen firmly against your skin at the injection site. Make sure it’s at a 90-degree angle (straight against the skin). Then press and hold the injection button (or if it’s an auto-inject style pen, pressing it against the skin may trigger the injection automatically, depending on the pen design). You will hear a click or will see an indicator move, and the injection will start. Keep the pen pressed against your skin for the full delivery time – the leaflet instructs keeping it in place for several seconds (e.g., until any indicator shows that the dose is delivered). This ensures you get the entire dose. You might hear a second click or see the window change color when it’s done. Tip: Always follow the specific pen’s instructions – the Wegovy pen instructions will tell you exactly how long to hold it. Typically, it’s around 10 seconds after clicking to ensure all medicine is injected.
-
After Injection: Once done, remove the pen from your skin. You can dispose of the pen (see the Storage and Disposal section below). If there’s a little bleeding at the site, you can press a cotton ball or tissue on it for a moment (don’t rub vigorously). If you notice a tiny lump or some mild redness, that’s okay and should subside. Use a bandage if needed. Do not reuse the pen – each Wegovy pen is single-use only. Also never share your pen with someone else, even if a needle wasn’t visibly exposed – it’s meant only for one-time personal use.
-
Timing: Use Wegovy once a week, on the same day each week if possiblemedicines.org.uk. You can choose a day that best fits your schedule (e.g., Sunday mornings). The injection can be taken at any time of day, with or without food. It doesn’t have to be timed with meals. Consistency is key – try not to vary the day week-to-week. If you need to change your weekly injection day, you can, as long as your last dose was at least 3 days (72 hours) agomedicines.org.uk. For example, if you usually inject on Mondays but need to switch to Thursdays, ensure at least 3 days have passed since the last dose, then take it on Thursday and continue weekly from that new day.
-
Forgotten Dose: If you forget a dose on your usual day, the general advice (from the manufacturer) is: If you remember within 5 days of the missed injection, take it as soon as you remember, then continue your weekly schedule from that new day. If more than 5 days have passed, skip the missed dose and just inject the next dose on your next scheduled daymedicines.org.uk. Do not double up or take two doses to make up for a missed one. If you’re ever unsure, check the patient leaflet or ask a pharmacist/doctor for advice on a missed Wegovy dose.
-
Support: When you are first prescribed Wegovy, the healthcare provider or pharmacist will usually give you training on how to use the pen. Before your first injection, ask your doctor, nurse or pharmacist to show you how to use it properlymedicines.org.uk. There are also illustrated instructions in the medication box and sometimes tutorial videos available. Don’t hesitate to seek guidance – proper technique ensures the medication works and reduces any discomfort.
-
During Dose Escalation: In the initial 16 weeks, your dose changes (see the next section on dosage schedule). That means you will use a different strength pen after every 4 weeks. Your pharmacy will usually supply the appropriate pens and clearly label them. Make sure to follow the schedule; using too high a dose too soon could increase side effects, while staying on a low dose longer than planned might slow down your progress. Only escalate the dose as directed by your doctor.
-
Lifestyle: Remember to maintain your diet and exercise routine when you start the injections. Wegovy will help you eat less, but what you eat should still be nutritious. Aim for balanced, healthy meals with plenty of vegetables, lean protein, and some healthy fats. Stay hydrated (especially since the medicine can cause you to lose fluids if you have any GI side effects). Some patients find it helpful to schedule their injection on a day when they’re off work the next day, just in case they feel a bit nauseous initially – although many people can carry on normal activities.
Most people become comfortable with the injections after a couple of weeks. The needles are very fine (the pen uses tiny needles, usually about 4 to 8 mm in length) and are designed for minimal pain. If you have a fear of needles, let your healthcare provider know; they can offer tips or alternatives (for example, having someone help you, numbing the skin with an ice cube briefly, etc.).
Wegovy’s design (single-use pens) means there’s no need to handle or see needles much – you just remove the cap, press, and dispose. This simplicity is intended to make the process as easy as possible for patients new to self-injection.
Wegovy Dosage Schedule – Titration and Maintenance Doses
To improve tolerability and minimize side effects, Wegovy’s dosage is increased gradually over several weeks. This stepwise increase (titration) allows your body to get used to the medication. Do not start on the full dose right away – doing so would likely cause intense side effects like nausea. Instead, you’ll follow a schedule like this:
Wegovy Dose Escalation Schedule:medicines.org.uk
-
Weeks 1–4: 0.25 mg once weekly (the starting dose).
-
Weeks 5–8: 0.5 mg once weekly.
-
Weeks 9–12: 1.0 mg once weekly.
-
Weeks 13–16: 1.7 mg once weekly.
-
Week 17 onwards: 2.4 mg once weekly (maintenance dose).
This means you’ll use the 0.25 mg pen for the first four injections, then move up to the 0.5 mg pen for the next four injections, and so on, until you reach 2.4 mg which is the full therapeutic dosemedicines.org.uk. Each pen is color-coded and labeled with the dose, to help avoid mix-ups.
Some important points about the dosage schedule:
-
Follow your doctor’s instructions: The above is the standard schedule, but your doctor might adjust it slightly depending on how you tolerate the medication. For example, if you experience a lot of nausea at a certain dose, they might have you stay on that dose a bit longer before increasing. Always follow the personalized plan your prescriber gives you.
-
Do not exceed 2.4 mg weekly: The recommended maintenance dose is 2.4 mg once weekly, and you should not go highermedicines.org.ukmedicines.org.uk. Higher doses have not been shown to provide much additional benefit but can increase side effects. Stick to the plan – once you’re at 2.4 mg weekly, that’s your ongoing weekly dose.
-
If you miss the escalation timing: Try not to prolong each step unnecessarily, as that may delay reaching the full effect. However, if you had to pause (say you missed a couple of weeks due to illness or supply issues), you don’t necessarily have to restart from 0.25 mg. Consult your doctor – in some cases if a short break occurred, you might resume at the last tolerated dose.
-
Monitoring: During the dose-escalation phase (first 4 months), you’ll typically have some check-ins with your healthcare provider. They may ask about side effects and weight changes, and ensure you’re comfortable moving to the next dose. It’s common to experience the most side effects (like nausea) during the initial weeks or whenever the dose is increased. The good news is that for many people, side effects improve over time and once you’re stable on the maintenance dose, your body often adjusts.
-
Maintenance phase: From week 17 onward, you will continue with 2.4 mg weekly. This is the long-term treatment dose. Clinical studies suggest that staying on Wegovy is needed to keep weight off – so you may be advised to continue for a year or two, or longer, depending on your weight loss goals and any official guidance. (NICE, the UK authority, currently suggests a 2-year limit under NHS supervision, but in private practice the duration can be individualized.) Your doctor will periodically review if the medication is still appropriate and effective for you.
-
Dose adjustments: If you cannot tolerate the 2.4 mg dose due to side effects, some patients can maintain on 1.7 mg weekly insteadgoodrx.com. While 2.4 mg is optimal, a maintenance dose of 1.7 mg is sometimes used for those who need a gentler regimen. Never adjust the dose on your own – always discuss with your prescriber if you feel you need to stay at a lower dose.
This graduated dosing is critical for safety and comfort. By starting low and going slow, Wegovy’s side effects (especially gastrointestinal ones) are made much more manageable. Be patient during this ramp-up period – you might not see dramatic weight loss in the first few weeks at 0.25 mg, but this step is laying the groundwork for success at higher doses. The appetite suppression will usually become more noticeable as you get to around 1 mg and above, though some people feel effects even on the small doses.
Side Effects of Wegovy (Common and Serious)
Like all medications, Wegovy can cause side effects. It’s important to know what to expect. The good news is that most side effects are mild-to-moderate and tend to happen early in treatment (or when increasing the dose), then improve over time as your body adapts. However, there are also some rare but serious side effects to be aware of, so you can take action if they occur.
Very common side effects (may affect more than 1 in 10 people)ema.europa.eu:
-
Nausea (feeling sick to your stomach). This is the most frequently reported side effect. You might feel queasy, especially after eating larger meals.
-
Vomiting (being sick). Some people do throw up, especially if they overeat or as the body adjusts to the medication.
-
Diarrhoea (loose stools) or Constipation – interestingly, semaglutide can cause either, as it affects the GI tract. You might experience one or the other at different times.
-
Stomach pain or indigestion. You might have mild abdominal discomfort or heartburn.
-
Headache. Some people report headaches when starting Wegovy.
-
Fatigue or dizziness. Occasionally, as you eat less or due to the medication’s effects, you might feel a bit tired or lightheaded, particularly in the first 3 monthsmedicines.org.uk. This could also be related to dehydration if you’ve had vomiting/diarrhoea.
These common side effects are usually temporary. For many patients, nausea is the main one, and it often improves after a few days or weeks on each dose. When you increase to the next dose, you might get a return of nausea, but it often is less severe than when you first started. By the time you reach the maintenance dose, many people find their body has adapted. Tips to manage nausea: eat smaller, bland meals; avoid very greasy or spicy foods; stay hydrated; ginger tea or ginger biscuits can help; try to eat slowly. If you get constipation, ensure you drink plenty of water and include fibre in your diet (fruits, veg, whole grains); for diarrhoea, also keep hydrated and consider a rehydration solution if it’s persistent. Over-the-counter remedies can be used (like paracetamol for headache, or anti-diarrhoeals, etc.) – ask your pharmacist for advice.
Less common side effects include belching, bloating, acid reflux, dizziness, and injection site reactions (like slight redness or itching at the injection spot). Most injection site reactions are mild and go away quickly. Because Wegovy slows stomach emptying, you might feel fullness or bloating more often. Some people also report taste changes or slightly reduced appetite for certain foods (which might actually help avoid high-calorie foods).
Serious side effects (rare but important):
-
Pancreatitis (acute): This is an uncommon side effect (estimated to affect less than 1 in 100 people). Pancreatitis is inflammation of the pancreas and can be serious. Warning signs include severe and persistent abdominal pain that can radiate to your back, sometimes accompanied by vomitingbhf.org.uk. The pain of pancreatitis is often very intense and doesn’t go away. If you experience severe stomach pain that doesn’t subside, especially if you also feel very unwell, stop using Wegovy and seek medical attention immediately. Pancreatitis usually requires hospital treatment. Fortunately, it’s a rare occurrence, but it’s a known risk with GLP-1 medications.
-
Gallbladder problems (Gallstones or cholecystitis): Rapid weight loss can predispose to gallstones. Some patients on Wegovy have developed gallstones or inflammation of the gallbladder. Signs can include pain in the upper right abdomen or right shoulder, especially after fatty meals, yellowing of the skin or eyes (jaundice), or fever and abdominal pain (in cholecystitis). This side effect is also uncommon (few percent of patients)medicines.org.uk. Let your doctor know if you have any history of gallstones. If you develop symptoms suggestive of gallbladder issues, they may do an ultrasound. Sometimes gallstones can pass on their own; other times they might require treatment or surgery.
-
Kidney problems (dehydration-related): The combination of eating less and possible vomiting or diarrhoea can lead to dehydration. In rare cases, this has led to acute kidney injury in patients on semaglutidebhf.org.uk. It’s especially a risk if you already have kidney disease. Make sure to drink plenty of fluids. If you can’t keep fluids down due to persistent vomiting, you should seek medical advice. Signs of dehydration or kidney issues include greatly reduced urination, dark urine, feeling faint, or kidney pain. Staying hydrated is very important if you have a day of bad GI side effects.
-
Severe allergic reactions: Very rare, but any medication can potentially cause an allergy. Signs of a serious allergic reaction (anaphylaxis) include swelling of the face, lips, tongue or throat, difficulty breathing, wheezing, severe rash or itching, fast heartbeat, dizziness or collapse. If after an injection you notice swelling or difficulty breathing, call emergency services immediately. Fortunately, confirmed anaphylactic reactions to Wegovy are extremely rare (again, <1 in 1,000). However, mild reactions like rash or itching have been reported; inform your doctor if you notice any unusual skin reactions.
-
Diabetic Retinopathy (in diabetics): If you have type 2 diabetes and diabetic eye disease (retinopathy), rapid improvements in blood sugar (from weight loss or the drug itself) could transiently worsen retinopathymedicines.org.uk. This was mainly observed with Ozempic in diabetics. If you’re diabetic, your doctor might check your eyes periodically. Report any visual changes.
-
Suicidal thoughts: This is extremely rare, but weight loss drugs in the same category (like liraglutide) have had very rare reports of mood changes. If you experience any depression or suicidal ideation, inform your healthcare provider right away. The vast majority of people do not have this issue, and some actually feel better mentally as they lose weight, but it’s important to be aware of any mood changes.
Most side effects of Wegovy can be managed with supportive care and are not dangerous. The most common issues – nausea, vomiting, diarrhoea – typically improve over timeema.europa.eu. Always tell your prescribing clinician about any side effects you experience. They may adjust your dose escalation, or suggest remedies. For example, if nausea is severe, they might prescribe an anti-nausea medicine for a short while, or advise you to stay on a lower dose longer. Never just suffer in silence – there are ways to make you more comfortable during treatment.
It’s important to read the patient information leaflet that comes with your Wegovy pack, which lists all potential side effects and what to do. And remember, report any unexpected or severe side effects. In the UK, new medications like Wegovy are under enhanced monitoring, so reporting side effects (via the Yellow Card scheme) helps gather more safety information.
Interactions and Precautions While on Wegovy
Drug interactions: The good news is that Wegovy (semaglutide) has relatively few direct drug interactions. It does not, for example, interact with common medications like paracetamol or birth control pills in any major way. However, there are some important considerations:
-
Diabetes medications: If you are on insulin or a sulfonylurea (like gliclazide, glimepiride) for diabetes, combining these with Wegovy can increase the risk of hypoglycaemia (low blood sugar). Semaglutide itself doesn’t usually cause low sugar in non-diabetics, but in diabetics on other glucose-lowering drugs, the combination effect can drop sugars too far. Your doctor will likely lower the dose of your sulfonylurea or insulin when starting Wegovy to mitigate this. Be alert for symptoms of low blood sugar: shakiness, sweating, confusion, dizziness. Always have a quick source of sugar handy if you’re diabetic on such medicines. If you get repeated hypos, inform your doctor – further medication adjustments may be needed.
-
Other GLP-1 or weight loss meds: Do not use Wegovy alongside other GLP-1 receptor agonists (like liraglutide/Saxenda, dulaglutide, exenatide). They all work similarly and using more than one won’t make you lose weight faster – it will just increase side effect risks. Also, avoid combining Wegovy with other prescription weight-loss drugs (such as phentermine, orlistat etc.) unless a doctor specifically advises, as safety of such combinations isn’t well studied.
-
Oral medications absorption: Wegovy slows gastric emptying, which in theory could affect the absorption of certain oral medicines. For most medicines this isn’t a big issue, but for medications that need to be taken with food or have critical absorption timing (like some antibiotics or thyroxine), monitor how you feel. If you take levothyroxine for thyroid, for example, continue to take it on an empty stomach in the morning and Wegovy shouldn’t interfere significantly. If you’re on any extended-release pills, there’s typically no problem. Just be aware and consult your doctor if you think a medicine isn’t working as expected after starting Wegovy.
-
Warfarin (blood thinner): Weight loss can affect warfarin dosing because as body weight changes, the effect of the drug can change. There’s no direct interaction with Wegovy, but if you’re on warfarin or other blood thinners, your clinic might monitor your INR a bit more closely while you lose weight.
-
Herbals and supplements: No specific herb or supplement is known to interact dangerously with Wegovy. However, always inform your healthcare provider about any supplements you take. Products that cause weight loss or lower blood sugar (like garcinia cambogia, or high-dose chromium, etc.) should be used cautiously as their effects could add up. There’s no known interaction with alcohol (Wegovy doesn’t interact with alcohol directly), but see precautions below on alcohol use.
Precautions and lifestyle considerations:
-
Alcohol: Combining alcohol with Wegovy (semaglutide) can be potentially harmful. Alcohol consumption may reduce the effectiveness of Wegovy and increase the risk of side effects such as dehydration and low blood sugar. It is recommended to avoid alcohol while taking this medication.
-
Driving and using machines: Wegovy itself is not a sedative and is unlikely to affect your ability to drive. However, some people may feel dizzy or lightheaded during the first few months of treatmentmedicines.org.uk, either due to lower blood sugar, lower blood pressure from weight loss, or as a side effect. If you feel dizzy or unwell, do not drive or operate heavy machinery until you feel normal again. Once your body adjusts, this usually isn’t a problem.
-
Surgery or medical procedures: If you are due to have surgery that involves general anaesthesia, let your surgeon or anesthetist know you are on Wegovymedicines.org.uk. Because Wegovy slows stomach emptying, there’s a concern about having food remaining in the stomach (aspiration risk) under anaesthesia. They may advise you to stop the medication a few days before the surgery as a precaution and to follow strict fasting instructions. Always inform any healthcare provider (dentist, etc.) that you are on Wegovy when discussing procedures.
-
Pregnancy prevention: As noted earlier, avoid pregnancy while on Wegovy. Use contraception and plan ahead – stop the medication at least 2 months before attempting to conceivemedicines.org.uk.
-
Dietary precautions: There’s no specific “Wegovy diet” you must follow, but given the appetite reduction, some people accidentally undereat or forget to drink enough fluids. Ensure you still get balanced nutrition. Focus on high-protein foods to preserve muscle as you lose weight, and eat high-fibre foods to help prevent constipation. Listen to your hunger cues (which will be lower) but don’t starve yourself; aim for a steady calorie deficit as recommended by your doctor or dietitian.
-
Hydration: We can’t say it enough – stay hydrated. Especially if you experience vomiting or diarrhoea. Dehydration can sneak up on you and cause kidney issues or make you feel faint.
-
Concurrent illnesses: If you get a stomach bug or another illness that causes a lot of vomiting/diarrhoea while on Wegovy, consider pausing the medication and contact your doctor. Losing fluids and not eating while on Wegovy could compound things. Once recovered, you can resume if your doctor says it’s okay.
-
Regular monitoring: While on Wegovy, you’ll likely have periodic check-ins. Expect your weight, blood pressure, and possibly blood tests (like blood sugar or thyroid levels) to be monitored. If you’re diabetic, you’ll monitor your glucose more closely at first. If you have any side effects or concerns, bring them up during these reviews.
-
Interactions with lab tests: Semaglutide itself doesn’t skew lab results, but rapid weight loss might improve some labs (like HbA1c, cholesterol) which is a good thing. If you’re on thyroid medication, weight loss might reduce the dose needed, etc. So you might see changes in your usual medical tests due to the weight loss effect.
In summary, keep your healthcare providers informed about all medicines and supplements you take. Wegovy is compatible with most common medications, but adjustments might be needed for diabetes treatments. Follow general health precautions like moderating alcohol, not driving if unwell, and staying hydrated. By doing so, you can safely continue your weight loss journey on Wegovy without unnecessary complications.
Storage and Disposal of Wegovy Pens
Proper storage of Wegovy is important to ensure the medication stays effective. The active ingredient is a protein (semaglutide) which can degrade if not stored correctly. Here’s how to store Wegovy and handle used pens:
-
Refrigeration: Store Wegovy pens in the refrigerator (2°C to 8°C) before use. Keep them in their original packaging carton to protect from light. Do not freeze Wegovy. If a pen has accidentally been frozen (for example, left in the freezer or in contact with the freezer element), do not use it – dispose of it. Similarly, keep it away from direct heat or sunlight. Your fridge is the best spot (not the freezer, and not in the fridge door if that area is prone to temperature swings). A cooler bag with an ice pack can be used for travel if needed (just don’t put the pen directly on ice – avoid freezing).
-
Room temperature: Wegovy can tolerate being at room temperature for a period of time. According to stability data, before removing the pen cap, you can keep a Wegovy pen at room temperature (below 30°C) for up to 28 days (4 weeks). The UK/European guideline actually indicates it can be up to 6 weeks below 30°C, but a safe rule of thumb is about a month. This means if you’re traveling or don’t have refrigeration for a short while, the medication won’t immediately spoil. However, avoid leaving it in hot environments (like a parked car in summer or on a windowsill). Once you’re back to a place with a fridge, continue storing it there. Before opening (cap on), refrigeration is ideal, but the above room-temp window is acceptable if needed. After opening (though with Wegovy “opening” just means removing the cap to inject), you will be using the dose immediately and then discarding the pen, so storage after first use isn’t applicable.
-
Pen handling: Keep the pens out of reach of children (and pets). The caps are child-resistant, but it’s medication, so store it securely. Each pen is individually sealed. Only take a pen out of the fridge when you’re going to use it, or if you’re taking that one pen with you somewhere for your next dose.
-
Expiry date: Check the expiry date on the pen or box. Don’t use Wegovy past its expiry date. If your medication expires or you end up not using a pen, see disposal instructions below.
-
Disposal of used pens: After you inject your dose, you’ll be left with a used pen (with a needle embedded in it). Do not throw used pens directly into the household rubbish where someone could get jabbed, and do not recycle them. The recommended way is to dispose of them in a sharps container (a rigid yellow medical waste bin). If you have a sharps bin from a previous medication, you can use that. Some pharmacies provide small sharps bins for patients on injectable medicines – ask your pharmacist. If you don’t have one, you can return used pens to the pharmacy or clinic for safe disposal. Never try to reuse a pen – it’s empty after one use, plus the needle will be dull. Also never share a pen with anyone – even though you’re done with it, it’s not safe for another person to use due to contamination risk.
-
Disposal of unused pens: If you have unused Wegovy (for example, if a pen expired, or if you stopped the medication and have some leftover), do not flush it down the toilet or sink. Take it to a pharmacy for proper disposal. UK pharmacies can dispose of medications safely, and it’s better for the environmentmedicines.org.uk. If in doubt, ask your pharmacist how to throw away medicines you don’t need.
-
Traveling: Plan ahead when traveling with Wegovy. Keep it cool – for instance, use an insulated travel bag with a cool pack (but not directly next to the ice pack). Airport security is used to people traveling with injectable medications; carry a note or your prescription just in case. Don’t check it in hold luggage if flying – carry it in hand luggage to avoid extreme temperatures and so it doesn’t get lost. Remember the 28-day room temp rule – a few hours out of the fridge during transit is fine. If you’re going somewhere without refrigeration for more than a few days, discuss with your doctor; sometimes they might advise using a cooled thermos or getting a local source at your destination.
-
Pen needles: Wegovy’s pen comes pre-fitted with a concealed needle, so you won’t be dealing with separate needles as you would with some other injections. Therefore, you won’t have loose needles to dispose of – the pen goes as one unit into the sharps bin. If for some reason a needle did detach (shouldn’t happen with Wegovy pens), handle it with a tool (not your fingers) and dispose in sharps container.
In essence, store Wegovy in the fridge, don’t freeze it, and keep it away from heat/light. If needed, it can be out of the fridge for a while (up to weeks) below 30°C, which gives flexibility for carrying your dose with you. Dispose of pens safely, treating them as you would a used syringe. Proper storage ensures each dose remains effective, and proper disposal keeps others safe and is environmentally responsible.
Safety and Regulatory Information (MHRA Approval and Black Triangle)
Wegovy is a relatively new medication in the UK, and there are some important safety and regulatory points to be aware of:
-
MHRA Approval: The UK’s Medicines and Healthcare products Regulatory Agency (MHRA) approved Wegovy in 2021 as a prescription medicine for weight management. This means Wegovy has been rigorously evaluated for safety, efficacy, and quality and is licensed for use in the UK for the specified indication (weight loss in obese/overweight adults with risk factors). In 2023, the National Institute for Health and Care Excellence (NICE) also issued guidance recommending Wegovy for certain patients in specialist settings, which underscored its clinical effectiveness. For you as a patient, this means Wegovy is an official, regulated treatment – not a supplement or unverified therapy. It’s backed by scientific evidence and oversight.
-
Black Triangle (▼) Symbol: In the UK and EU, Wegovy is marked with a “black triangle” (▼) in its labeling and literaturemedicines.org.uk. You might even see this symbol on the package or patient leaflet. The black triangle indicates that Wegovy is subject to additional monitoring by regulatory authorities. This doesn’t mean the drug is unsafe; rather, it means it’s new, and the regulators want to gather as much information as possible about its safety in real-world use. All side effects should be reported so that any new or rare safety issues can be identified quickly.
-
Reporting Side Effects: Because of the black triangle, patients and healthcare professionals are encouraged to report any side effects to the MHRA’s Yellow Card scheme. You can do this online or via a Yellow Card app. Even if you’re not sure if a symptom is related to Wegovy, reporting it helps build data. This ongoing monitoring is a normal process for new medicines and helps ensure long-term safety. When you receive your medication, the pharmacy might give you information on how to report side effects. Participating in this system contributes to the safe use of Wegovy for everyone.
-
Known Safety Profile: So far, the safety profile of Wegovy in trials and early real-world use aligns with what we’ve discussed (mostly gastrointestinal side effects, etc.). There is no indication of any widespread unforeseen issues, but the additional monitoring helps detect rare events. For example, as mentioned, there is a theoretical cancer risk (thyroid tumors in rodents), but human data has not shown a causal linkapclabs.co.uk. The MHRA and EMA keep a close watch; in fact, in 2024 the EMA noted a safety signal to further investigate any link between GLP-1 drugs and thyroid cancer, but as of now, no direct evidence of danger in humans has been confirmed. The black triangle ensures that any such signals are taken seriously and examined.
-
Legal Status: Wegovy is a prescription-only medicine (POM) in the UK. You cannot buy it over the counter. Any legitimate supply will require a prescription from a registered doctor. Online pharmacies offering Wegovy will have you go through a consultation with a prescriber. Be wary of any source that doesn’t require a prescription – sadly, the popularity of Wegovy has led to some counterfeit products on the black market. Always obtain it from a reputable UK pharmacy or clinic.
-
Regulatory Limits: Under NHS guidance, Wegovy (when supplied through NHS weight management services) is generally intended for a maximum of 2 years of continuous use, as an aid to kick-start and maintain weight loss. In private use, your doctor will decide on the duration of therapy based on your progress. It’s not yet clear if people will need to stay on Wegovy indefinitely to keep weight off or if some can transition off after reaching goals (trials suggest many will regain weight if the drug is stoppedema.europa.eu). This is an area of ongoing research and discussion among healthcare professionals. The key point: Wegovy is considered part of a long-term weight management strategy, and stopping should always be a medical decision.
-
Black Triangle Removal: The black triangle is not permanent; it’s usually removed after a few years when sufficient post-marketing data have been collected. So in a couple of years, Wegovy might no longer have the symbol, once authorities are satisfied that its safety profile is fully characterized. For now, when you see (▼) next to Wegovy in any materials, just remember it’s under extra observation.
-
Patient support: Because Wegovy is new, Novo Nordisk (the manufacturer) often provides patient support materials – for example, a patient brochure, injection training guides, and possibly access to a support app or website. These resources can be very helpful. They might help with tracking your doses, dietary advice, etc. Check if your pharmacy includes any leaflets or info on support programs.
-
Medicines Guide and Further Info: Always read the patient information leaflet in your pack for full details on Wegovy. For healthcare professionals, the Summary of Product Characteristics (SmPC) provides extensive info, which you can ask your doctor about if you have detailed questions. As part of regulatory approval, Wegovy’s manufacturer must also continue various studies and reporting to the MHRA/EMA to ensure ongoing safety and efficacy data are collected.
-
Confidence in Quality: Being an approved medication means each batch of Wegovy is manufactured to high standards. You might have heard about supply shortages in the news (due to high demand globally). If there are any supply issues, do not be tempted to get semaglutide from unofficial sources or use veterinary or research-grade products (some unscrupulous sellers market “semaglutide” vials – avoid these). Stick with the regulated Wegovy product for your safety.
In summary, Wegovy is a certified treatment in the UK with proven benefits in weight loss. It carries a black triangle symbol (▼), indicating it’s under additional safety monitoring now that it’s newly on the marketmedicines.org.uk. This is a normal part of the introduction of any new medication. Use Wegovy only under medical supervision, and report any side effects to ensure the continued safe use of this medication. With the combination of clinical oversight, patient reporting, and regulatory monitoring, you can feel confident that your journey with Wegovy is being supported and watched over by multiple layers of healthcare systems.
