Written by healthwords.ai's team of doctors and pharmacists based in UK | Updated: 25 Apr 2023 | 2 min read

Esomeprazole is a medication used in the treatment of heartburn and stomach ulcers. It is also used to protect your stomach lining from medications such as ibuprofen, naproxen and diclofenac. It works by reducing the amount of acid produced by the stomach. Esomeprazole can come in many different formulations; however, tablets are the most common and small amounts can be purchased from a pharmacy, as well as shops and supermarkets.

Who is it for?

Esomeprazole is for use by adults over the age of 18. When used for the treatment of a stomach ulcer, it may be combined with antibiotic medication to treat a bacteria called H-pylori. Esomeprazole is also used for other conditions where stomach acid suppression is necessary. It can also be prescribed for children to treat these conditions however, this is only ever done under the close supervision of a doctor.

How does it work?

Esomeprazole belongs to a class of medication called proton pump inhibitors (PPI) and works by reducing the amount of acid produced in the stomach. The medication switches off the stomach acid-producing cells, meaning there is less acid in the stomach to irritate the stomach lining and food pipe (oesophagus).

Should anyone avoid taking it?

You should speak to your doctor before starting taking this medication if you are pregnant, planning to become pregnant, or breastfeeding. A discussion with your doctor would also be sensible if you are known to have low levels of magnesium, or have recently been suffering from diarrhoea. You should speak to your doctor if you are at risk of osteoporosis (weakened bones), as the medication can interfere with calcium absorption which may in turn further weaken your bones.
