Who can take esomeprazole
Most adults can take esomeprazole. Children should only have esomeprazole if a doctor prescribes it.
Who may not be able to take esomeprazole
Esomeprazole is not suitable for some people. To make sure it's safe for you, tell your doctor if you:
- have ever had an allergic reaction to esomeprazole or any other medicine
- have liver problems
- are due to have an endoscopy - problems usually found during this procedure may not show up if you've used esomeprazole
If you're using esomeprazole that you have bought from a shop or pharmacy without a prescription, then you should speak to your doctor before taking it if you:
- are losing weight without trying
- keep being sick (vomiting), or are vomiting blood (this might look like dark coffee grounds)
- feel weak or your skin looks paler than usual (this may not be as noticeable on brown or black skin)
- have blood in your poo (your poo may look black or like tar)
- have chest or stomach pain
- have diarrhoea that is severe or does not get better
- have problems with swallowing
