What OMEPRAL is used for
OMEPRAL 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
OMEPRAL is also taken to help stop reflux oesophagitis coming back or relapsing.
OMEPRAL 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.
OMEPRAL 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 OMEPRAL 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.
OMEPRAL is also used to heal and prevent ulcers associated with NSAIDs.
OMEPRAL 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
How OMEPRAL Works
OMEPRAL 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.
