Lansoprazole Capsules
From: £8.99
Or £8.09 / month
Lansoprazole is a widely prescribed proton pump inhibitor (PPI) used across the UK for acid-related digestive conditions. It works in the same way as Omeprazole — blocking acid production at source — and is broadly comparable in effectiveness. Taken once daily before food, it is used for GORD, frequent heartburn, gastric ulcers, and H. pylori eradication.

Decription
What Is Lansoprazole?
Lansoprazole belongs to a group of medicines known as proton pump inhibitors. These medicines reduce the amount of acid produced by the stomach. Excess acid can irritate the oesophagus and stomach lining, leading to heartburn, inflammation, and ulcers. By lowering acid production, Lansoprazole allows irritated tissue to heal and helps prevent further damage. Capsules should not be crushed or chewed, as they contain gastro-resistant granules.
What Conditions Can Lansoprazole Treat?
Lansoprazole is licensed in the UK for: GORD (reduces acid exposure and supports healing of inflamed oesophageal tissue), heartburn and acid regurgitation (sustained symptom control), gastric and duodenal ulcers (promotes healing), prevention of NSAID-associated ulcers, and Helicobacter pylori eradication (used alongside antibiotics). Treatment decisions follow NICE guidance.
How Does Lansoprazole Work?
The stomach produces acid via structures called proton pumps. Lansoprazole blocks these pumps, significantly reducing acid secretion. Acid reduction begins within 1–2 hours of taking a dose. Maximum therapeutic benefit develops over several days of consistent use. Regular daily dosing is important for optimal results.
How to Take Lansoprazole Capsules
The usual adult dose for reflux is 15–30mg once daily before breakfast. Some individuals may require 30mg daily depending on severity. Swallow capsules whole with water. Do not crush or chew the granules inside. If prescribed twice daily, the second dose is taken before the evening meal.
Lansoprazole vs Omeprazole vs Famotidine
Lansoprazole and Omeprazole are both PPIs working in the same way. They are broadly comparable in effectiveness, although some individuals respond better to one than the other. Famotidine is an H2 receptor blocker providing faster onset but shorter-duration acid suppression — suitable for intermittent or on-demand use. Your pharmacist will assess which option is most appropriate.
FAQ
Q: How quickly does Lansoprazole work?
A: Acid reduction begins within 1–2 hours of the first dose. However, maximum therapeutic benefit builds over several days of consistent daily use.
Q: Is Lansoprazole the same as Omeprazole?
A: Both are PPIs and work in the same way. They are broadly comparable in effectiveness. Individual patients sometimes respond better to one than the other. Your pharmacist will advise based on your symptoms and history.
Q: How long should I take Lansoprazole?
A: Standard courses for reflux typically last 4 to 8 weeks. Via online pharmacisting, an initial shorter supply (14–28 days) may be provided. If symptoms persist or worsen beyond this timeframe, further medical review is recommended.
Q: Can Lansoprazole be taken during pregnancy?
A: Lansoprazole may be used during pregnancy when clinically appropriate. Suitability will be assessed individually. Declare pregnancy or breastfeeding during your consultation.
Q: What are the most important drug interactions?
A: Important interactions include methotrexate, warfarin, digoxin, HIV medicines, certain antifungals, and anticoagulants. Always provide a full medication history during your consultation.
