Popular brand names:

Lancap, Lansoloc, Lanzor

Drug group:

Anti-ulcer drug

Prescription needed?

Yes (except for Lansoloc OTC)

 

What does it do?

Lansoprazole is used in the treatment of:

  • Gastro-oesophageal reflux disease (GORD): a chronic condition where stomach acid rises into the oesophagus
  • Zollinger-Ellison syndrome: excess stomach acid production leading to ulceration
  • Peptic ulcers: used either alone, or in combination with a 7-day course of antibiotics (triple therapy, to eradicate Helicobacter pylori bacteria, the main cause of peptic ulcers)

 

How does it work?

Lansoprazole is a proton pump inhibitor - it reduces the amount of acid produced by the stomach, thereby preventing or treating ulceration. 

 

How should it be used?

  • Lansoprazole may mask the symptoms of stomach cancer - a gastro-scope may be required before treatment is started to first rule out the possibility of this disease
  • Best taken in the morning before food
  • Avoid spicy/acidic foods and alcohol – these may aggravate the underlying condition

 

What is the typical dosage?

Your doctor will recommend a dosage tailored to your need, but typically:

  • Peptic ulcer/gastro-oesophageal reflux disease: 30mg taken once daily
  • NSAID-induced ulcer/acid-related dyspepsia: 15–30mg taken once daily
  • Zollinger-Ellison syndrome: initially 60mg daily, dose adjusted according to response
  • Pylori-associated ulcer: 30mg in the morning, and 30mg in the evening

When should I stop using it?
