Clear Start Consultation

Lansoprazole is a widely prescribed medication for managing conditions caused by excess stomach acid. It is commonly used to treat heartburn, acid reflux, gastro-oesophageal reflux disease (GORD), stomach ulcers, and other conditions where reduction of stomach acid is beneficial. Lansoprazole is part of a class of drugs known as proton pump inhibitors (PPIs) and is available in capsule and orodispersible tablet forms for convenient use.

How It Works
Lansoprazole works by selectively blocking the hydrogen/potassium ATPase enzyme system, also known as the “proton pump,” in the stomach lining. This system is responsible for the final step of acid production. By inhibiting this pump, Lansoprazole effectively reduces the amount of acid the stomach produces, creating a more favourable environment for healing ulcers and relieving acid-related symptoms. It is usually taken once daily and provides long-lasting acid suppression.

Why Choose Lansoprazole
Lansoprazole is a well-established and clinically effective treatment for acid-related disorders. It offers once-daily dosing, which supports compliance and ease of use. The medicine is available in both capsule and dispersible forms, allowing for flexibility in patients who have difficulty swallowing. Lansoprazole typically begins to work within a few days of use, and sustained treatment helps prevent ulcer recurrence, reduce reflux episodes, and maintain long-term gastrointestinal health.

Important Note
Lansoprazole should only be used under medical guidance and for the duration prescribed. Long-term use may be associated with increased risks such as bone fractures, vitamin B12 deficiency, and low magnesium levels. It should not be used for immediate relief of heartburn symptoms. Patients should inform their doctor of all other medications and medical conditions, particularly if they are taking antiretrovirals, anticoagulants, or anti-fungal treatments. Regular monitoring may be required for prolonged treatment.

  • Lansoprazole starts reducing stomach acid within a few hours, but noticeable relief may take a few days.
  • Lansoprazole is often prescribed for short-term use, but long-term treatment may be necessary for some conditions. A doctor should monitor extended use.
  • Take it as soon as you remember. If it’s nearly time for the next dose, skip the missed one. Do not take two doses at once.
  • Some medications can interact with Lansoprazole, including certain HIV treatments, antifungal drugs, and blood thinners. Speak to a doctor before combining treatments.
  • There are no strict dietary restrictions, but taking Lansoprazole before meals ensures better absorption. Limiting acidic, spicy, or fatty foods may help manage reflux symptoms.
