What ESOMEPRAZOLE AN is used for

Esomeprazole AN will only be used if you are unable to take tablets.

Reflux Oesophagitis

Esomeprazole AN is used to treat reflux oesophagitis or reflux disease in the short-term. This can be caused by “washing back” (reflux) of food and acid from the stomach into the food pipe (oesophagus).

Reflux can cause a burning sensation in the chest rising up to the throat, also known as heartburn.

Bleeding Peptic Ulcers

Peptic ulcers are ulcers in the stomach or duodenum (tube leading out from the stomach). When these ulcers become severe enough, they start to bleed. Esomeprazole AN can be injected into your veins to treat these bleeding ulcers. Treatment with Esomeprazole AN should be followed with other therapy to reduce the amount of acid made by the stomach. This is to help your ulcer/s to heal.

Upper gastrointestinal symptoms associated with non-steroidal anti-inflammatory drugs (NSAIDs) therapy

If you are unable to eat or drink, Esomeprazole AN may be given to treat the symptoms of pain or discomfort in the stomach caused by NSAIDs (medicines used to treat pain or inflammation). Esomeprazole AN may also be used to help and prevent ulcers caused by NSAIDs.


Esomeprazole AN is a type of medicine called a proton-pump inhibitor.

Esomeprazole AN works by decreasing the amount of acid made by the stomach, to give relief of symptoms and allow healing to take place. This does not stop food being digested in the normal way.

Your doctor will have explained why you are being treated with Esomeprazole AN and told you what dose you will be given.

Follow all directions given to you by your doctor carefully. They may differ from the information contained in this leaflet.

Your doctor may prescribe this medicine for another use. Ask your doctor if you want more information.

There is no evidence that Esomeprazole AN is addictive.
