1. Why am I using Omeprazole Sandoz?

Omeprazole Sandoz contains the active ingredient omeprazole (as magnesium). Omeprazole Sandoz 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.

Reflux Oesophagitis

Omeprazole Sandoz 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 to the throat, also known as heartburn.

Omeprazole Sandoz is also taken to help stop reflux oesophagitis coming back or relapsing.

Peptic Ulcers

Omeprazole Sandoz 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 of the stomach.

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

Omeprazole Sandoz is also used to help stop gastric and duodenal ulcers from coming back.

Peptic Ulcers Associated with Helicobacter pylori Infection

Omeprazole Sandoz is used to treat peptic ulcers associated with helicobacter pylori infection.

Most people who have peptic ulcer also have a bacterium called Helicobacter pylori in their stomach. When Omeprazole Sandoz 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.

Omeprazole Sandoz is used to heal and prevent ulcers associated with NSAIDs.

Zollinger-Ellison syndrome

Omeprazole Sandoz is also used to treat a rare condition called Zollinger-Ellison syndrome.

This syndrome is where the stomach produces large amounts of acid, much more than in ulcers or reflux disease.

There is no evidence that Omeprazole Sandoz is addictive.
