How Lansoprazole works
Lansoprazole is a type of medicine called a proton pump inhibitor (PPI). Proton pumps are enzymes in the lining of your stomach that help it make acid to digest food. Lansoprazole prevents these proton pumps working properly, reducing the amount of acid the stomach makes.
It usually starts working within 2 to 3 days, but it may take up to 4 weeks for it to work fully.
How to take Lansoprazole
Take the dose on your prescription, usually once daily in the morning at least 30 minutes before food. Depending on your condition, this may be 15mg or 30mg. Place the orodispersible tablet on your tongue and allow it to disperse, then swallow the small pellets without chewing or crushing them.
Some products can be dispersed in water and given with an oral syringe. The water volume and syringe size differ between brands and strengths, so follow the supplied leaflet and ask a pharmacist to show you the method for your tablets.
Your prescriber may adjust the dose according to your response. If symptoms persist or worsen, speak to your doctor or pharmacist.
What is heartburn & acid reflux
Heartburn is an uncomfortable burning sensation feeling in your chest that can travel up your neck and throat. Usually the stomach acid is kept in the stomach by the lower oesophageal sphincter. When it isn't working properly stomach acid is allowed to travel up into the oesophagus, causing a burning sensation. If it is a chronic condition it is known as gastro-oesophageal reflux disease (GORD). It can affect anyone sometimes with no obvious cause.
Common symptoms are:
- Heartburn
- An unpleasant taste in the mouth
- Cough or hiccups
- Bad breathe

Your symptoms may be worse after eating, when lying down or bending over.
Sometimes it is caused by or made worse by:
- Obesity
- Alcohol
- Smoking
- Pregnancy
- Certain foods - spicy, acid or fatty foods
- Stress
- Certain medicines such as NSAIDs
- Bacterial infections
- Stomach ulcers
- Hiatus hernia
