Description
Lansoprazole orodispersible tablets are a fast-dissolving form of a proton pump inhibitor (PPI) used to reduce stomach acid. They are commonly used for heartburn, acid reflux and gastro-oesophageal reflux disease (GERD/GORD), and may also be prescribed for ulcer-related conditions. Because the tablet dissolves on the tongue, it can be a practical option for people who find capsules hard to swallow.

Why choose an orodispersible tablet?
- Convenient administration: place on the tongue and allow it to dissolve, then swallow.
- Useful if you struggle with capsules or need an easier option when travelling or at work.
- Common UK brand-name wording includes ‘Zoton FasTabs’ (a lansoprazole orodispersible tablet).
What lansoprazole treats
- Heartburn and acid regurgitation (acid coming up into the throat).
- Acid reflux and GERD/GORD (including reflux oesophagitis when diagnosed).
- Stomach or duodenal ulcers and ulcer prevention in higher-risk patients when prescribed.
- Specialist uses such as Helicobacter pylori eradication (as part of combination therapy) or Zollinger-Ellison syndrome.
Choosing the right strength (15mg vs 30mg)
The best strength depends on your symptoms, diagnosis, and response. A clinician will confirm what is appropriate for you.
- 15mg: often used for milder reflux symptoms, maintenance, or prevention plans where clinically appropriate.
- 30mg: often used for more persistent symptoms or where stronger acid suppression is needed.
- If symptoms are not controlled, your prescriber may adjust dose or review the diagnosis and treatment plan.
How lansoprazole works
Lansoprazole reduces acid production by blocking proton pumps (enzymes) in the stomach lining. Lower acid levels can ease burning and regurgitation symptoms and help irritated tissue in the food pipe (oesophagus) heal.
How to take lansoprazole orodispersible tablets
- Take the tablet before food (often before breakfast) as advised by your prescriber.
- Place the tablet on your tongue and suck gently – it dissolves rapidly in the mouth.
- Swallow once dissolved. A sip of water is optional if you prefer.
- If you are prescribed twice daily dosing, take one dose in the morning and one in the evening.
- Do not take more than prescribed. If you miss a dose, take it when you remember unless it is nearly time for the next dose (do not double up).
If you use antacids or alginates for occasional breakthrough symptoms, separate them from your PPI dose if advised by your pharmacist.
How long does treatment last?
Treatment length depends on the condition being treated. For heartburn and acid regurgitation, a common course is up to 4 weeks, with review if symptoms persist. Ulcer or reflux-oesophagitis treatment courses can be longer. If symptoms do not improve or keep returning, you should be reviewed to confirm the diagnosis and safest long-term plan.
Important: check for alarm symptoms
Seek medical advice urgently (before starting or while taking a PPI) if you have:
- Unexplained weight loss.
- Trouble swallowing or persistent pain when swallowing.
- Vomiting repeatedly, vomiting blood, or black/tarry stools.
- Severe or persistent stomach/chest pain.
Ingredients note (aspartame / PKU and sugar intolerance)
Some lansoprazole orodispersible tablets contain aspartame, which is a source of phenylalanine and may be harmful if you have phenylketonuria (PKU). Some formulations also contain sugars such as sucrose. Always check the patient leaflet or ask your pharmacist if you have PKU or sugar intolerance.
Medicine interactions (tell your prescriber)
Lansoprazole can interact with some medicines or affect absorption of medicines that depend on stomach acidity.
- Clopidogrel: omeprazole and esomeprazole may reduce clopidogrel effect; lansoprazole is commonly used as an alternative if stomach protection is needed.
- Warfarin and other blood thinners: may require monitoring in some patients.
- Some antifungals and antivirals: absorption can be affected when stomach acidity changes.
Possible side effects
Common side effects may include:
- Headache.
- Stomach pain, nausea, diarrhoea or constipation.
- Wind (flatulence) or dry mouth.
- Dizziness in some people.
With prolonged PPI use, low magnesium has been reported (especially after months to years). Your clinician will advise on the lowest effective dose for the shortest appropriate duration and whether you need review or monitoring.
