What Esomeprazole VIATRIS is used for

Reflux Oesophagitis

ESOMEPRAZOLE VIATRIS is taken to treat reflux oesophagitis. 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.

ESOMEPRAZOLE VIATRIS is also taken to help stop reflux oesophagitis coming back or relapsing.

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

ESOMEPRAZOLE VIATRIS is taken to treat the symptoms of pain or discomfort, in the stomach caused by NSAIDs, a type of medicine for pain or inflammation.

ESOMEPRAZOLE VIATRIS is also taken to help heal and prevent ulcers caused by NSAIDs.

Peptic Ulcers Associated with Helicobacter pylori Infection

Most people who have a peptic (gastric and duodenal) ulcer also have a bacterium called Helicobacter pylori in their stomach.

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.

If you have a peptic ulcer, your doctor will prescribe ESOMEPRAZOLE VIATRIS with antibiotics. When ESOMEPRAZOLE VIATRIS and antibiotics are taken together, they work to kill the bacterium and let your ulcer heal. You may need further treatment with antibiotics.

Zollinger-Ellison Syndrome

ESOMEPRAZOLE VIATRIS 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.

Bleeding Peptic Ulcers

When peptic ulcers become severe enough, they start to bleed. You may receive treatment injected into your veins initially. This treatment may be followed with ESOMEPRAZOLE VIATRIS tablets or granules prescribed by your doctor for a longer period of time. This is to help your ulcer/s to heal.

How Esomeprazole VIATRIS works

ESOMEPRAZOLE VIATRIS is a type of medicine called a protonpump 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 want more information.

Your doctor may have prescribed ESOMEPRAZOLE VIATRIS for another reason.

There is no evidence that ESOMEPRAZOLE VIATRIS is addictive.
