What this medicine is used for

Reflux Oesophagitis
APO-OMEPRAZOLE is used to treat the symptoms of reflux oesophagitis or reflux disease. 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.

APO-OMEPRAZOLE is also taken to help stop reflux oesophagitis coming back or relapsing.

Peptic Ulcers
APO-OMEPRAZOLE is used to treat peptic ulcers. Depending on the position of the ulcer it is called a gastric or duodenal ulcer. A gastric ulcer occurs in the stomach. A duodenal ulcer occurs in the duodenum which is the tube leading out from the stomach.

These ulcers can be caused by too much acid being made in the stomach.

APO-OMEPRAZOLE is also used to help stop gastric or duodenal ulcers coming back.

Peptic Ulcers Associated with Helicobacter pylori Infection
Most people who have a peptic ulcer also have a bacterium called Helicobacter pylori in their stomach.

When APO-OMEPRAZOLE is taken with antibiotics, they work to kill the bacterium and let your ulcer heal. You may need further treatment with antibiotics.

Peptic Ulcers Associated with Non-steroidal Anti-Inflammatory Drugs (NSAIDs)
Some peptic ulcers are caused by taking medicines called non-steroidal anti-inflammatory drugs (NSAIDs), a type of medicine used to treat pain or inflammation. APO-OMEPRAZOLE is also used to heal and prevent ulcers associated with NSAIDs.

Zollinger-Ellison Syndrome
APO-OMEPRAZOLE is also used to treat a rare condition called Zollinger-Ellison syndrome, where the stomach produces large amounts of acid, much more than in ulcers or reflux disease.

How it works

APO-OMEPRAZOLE is a type of medicine called a proton-pump inhibitor. It 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.

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

Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may prescribe this medicine for another reason.

There is no evidence that this medicine is addictive.

This medicine is available only with a doctor's prescription.
