Overview

If heartburn or acid reflux is stopping you from enjoying meals, keeping you awake at night, or leaving you constantly reaching for quick fixes, Lansoprazole could be the answer. This trusted treatment works by reducing excess stomach acid, easing burning pain and indigestion, and protecting your food pipe (oesophagus) from further irritation. With Lansoprazole, you can finally focus on living your life — not your symptoms.

At SwiftMedi, every request is carefully reviewed by a UK-registered prescriber through a secure online consultation, with discreet delivery straight to your door.


What is Lansoprazole 


Lansoprazole is a proton pump inhibitor (PPI) that works by reducing the amount of acid produced in the stomach. By tackling the root cause of reflux, it not only relieves symptoms but also allows the oesophagus and stomach lining to heal, helping prevent further irritation and discomfort.

It is commonly prescribed for frequent heartburn and acid reflux, gastro-oesophageal reflux disease (GORD), and for the treatment and prevention of stomach and duodenal ulcers. Lansoprazole is also used to protect the stomach in people who need long-term treatment with NSAIDs.

Many patients begin to notice improvement within just a few days, with the full benefit usually seen after 1–2 weeks of consistent use, making it a reliable option for both short-term relief and long-term management of reflux conditions.

Directions

  • Usual dose: 15mg to 30mg once daily.
  • Take in the morning, at least 30 minutes before food.
  • Swallow capsules whole with water — do not crush or chew.
  • Duration depends on your condition — from 2–4 weeks for short-term heartburn to longer courses for GORD or ulcers.


Always follow the exact instructions from your prescriber.

Side Effects

Like all medicines, lansoprazole can cause side effects, although not everyone will experience them. Most are mild, short-lived, and improve as your body adjusts to treatment.

Common (may affect up to 1 in 10 people):

  • Headache – usually mild and temporary.
  • Stomach pain, constipation, diarrhoea, or nausea – digestive upset is the most frequently reported effect but is generally mild.
  • Flatulence (wind) – some people may notice bloating or excess gas.


Uncommon (may affect up to 1 in 100 people):

  • Dizziness, tiredness, or sleep problems – these may affect alertness; avoid driving if you feel unwell.
  • Dry mouth or taste changes – usually mild and temporary.
  • Skin rash or itching – generally mild, but seek advice if persistent.


Rare but serious (seek urgent medical advice):

  • Severe allergic reaction (anaphylaxis) – symptoms may include swelling of the face, lips, tongue, or throat, difficulty breathing, or a sudden rash.
  • Severe stomach pain or persistent vomiting – may indicate bleeding or complications from ulcers.
  • Yellowing of the skin or eyes (jaundice) – a possible sign of liver problems.


Most people tolerate lansoprazole well, and side effects (if they do occur) are usually mild. If you are concerned about any symptoms, or if they do not improve, speak to your doctor, pharmacist, or prescriber.

Disclaimer: This is not a complete list of side effects. Always read the patient information leaflet provided with your medicine for full details. If you experience severe or worrying symptoms, seek medical advice straight away. In an emergency, call 999 or go to A&E.
