How Xenical Works (Orlistat 120mg)
Xenical works locally in your digestive system. Orlistat reduces the activity of enzymes that break down fat, so some of the fat you eat isn’t absorbed and is passed out of the body. Because it acts on dietary fat, Xenical works best when your daily fat intake is moderated and distributed across meals.
Who Can Use Xenical 120mg?
Xenical is indicated for adults with:
- A BMI of 30 kg/m² or higher, or
- A BMI of 28 kg/m² or higher with associated risk factors (for example, certain weight-related health conditions).
Xenical is not suitable for everyone. A clinician will review your medical questionnaire before prescribing. Do not use Xenical if you have chronic malabsorption syndrome or cholestasis, and it must not be used while breastfeeding.
How to Take Xenical 120mg Capsules
Standard dose: take 1 capsule (120mg) with water immediately before, during, or up to 1 hour after each main meal (breakfast, lunch, dinner).
- If you miss a meal, or the meal contains no fat, skip that dose.
- Do not take more than 3 capsules per day.
- High-fat meals increase the chance of unwanted bowel effects—keep fat moderate and spread across meals.
Diet Tips to Reduce Side Effects and Improve Results
Xenical is designed to be used with a nutritionally balanced, mildly hypocaloric diet. A practical approach is to keep fat around 30% of daily calories and distribute fat across three main meals.
- Prioritise lean proteins and high-fibre foods (vegetables, fruit, whole grains).
- Avoid very high-fat meals (these can trigger oily stools or urgent bowel movements).
- Limit high-fat snacks between meals (e.g., biscuits, chocolate, savoury snacks).
Vitamins and Xenical (A, D, E, K)
Because orlistat can reduce absorption of some fat-soluble nutrients, you may be advised to take a multivitamin supplement. A common recommendation is to take the supplement at least 2 hours before or after Xenical—many people find bedtime easiest.

FAQs
- How quickly does Xenical work?
Xenical starts working when dietary fat is present. Many people notice bowel-related effects early, while weight-loss results depend on diet, consistency, and starting weight. A clinician may review progress after 12 weeks.
- Do I need to change my diet on Xenical?
Yes. Xenical is intended to be used with a mildly hypocaloric, balanced diet. Keeping fat moderate and spread across meals helps both results and tolerability.
- Can I take Xenical if I skip a meal?
If you miss a meal, or your meal contains no fat, skip that Xenical dose.
- Should I take vitamins with Xenical?
You may be advised to take a multivitamin containing fat-soluble vitamins. Take it at least 2 hours before or after Xenical (often at bedtime).
- Is Xenical the same as Orlistat 120mg?
Xenical is the branded version of orlistat 120mg. They contain the same active ingredient and are used in similar ways.
