What this medicine is used for

The name of your medicine is Chemmart Omeprazole. It contains the active ingredient Omeprazole.

It is used to treat:

  • Reflux Oesophagitis
    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.
    Omeprazole is also used to help stop reflux oesophagitis coming back or relapsing.
  • Peptic Ulcers
    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.
    Omeprazole is also used to help stop peptic or duodenal ulcers coming back.
  • Peptic Ulcers Associated with Helicobacter pylori Infection
    Helicobacter pylori is a bacteria that often occurs in the stomach together with peptic ulcers.
    When omeprazole is taken together with an antibiotic, they work together to kill the bacteria 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, swelling or inflammation, including arthritis and joint pain.
    Omeprazole is used to treat and help to prevent ulcers developing, which are associated with long-term use of NSAIDs.
  • Zollinger-Ellison Syndrome
    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.

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

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

How it works

Omeprazole belongs to a group of medicines called proton-pump inhibitors.

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.

There is no evidence that this medicine is addictive.

Use in children

This medicine should not be used in children.
