WHAT OMEPRAZOLE SANDOZ IS USED FOR
The name of your medicine is Omeprazole Sandoz. It contains the active ingredient omeprazole (as magnesium).
Omeprazole Sandoz is used to treat the following conditions:
This medicine is used to treat reflux oesophagitis (reflux disease) and to help stop it coming back or relapsing. Reflux can
be caused by "washing back" (reflux) of food and acid from the stomach into the food pipe (oesophagus). Reflux can cause heartburn,
a burning sensation in the chest rising up to the throat.
Treatment and prevention of peptic ulcers
Omeprazole Sandoz is used to help heal 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. This can be caused in part by too much
acid being made in the stomach.
This medicine is also used to help stop gastric and duodenal ulcers from coming back.
Combination therapy for the treatment of peptic ulcers associated with Helicobacter pylori infection
Helicobacter pylori is a bacteria that often occurs in the stomach together with peptic ulcers. It is important to kill Helicobacter
pylori to let your peptic ulcer heal. Omeprazole Sandoz is usually combined with two antibiotics to help kill this bacteria.
However, it is possible that the antibiotics might not always be able to kill Helicobacter pylori.
Treatment and prevention of peptic ulcers associated with non-steroidal anti-inflammatory drugs (NSAIDs)
Non-steroidal anti-inflammatory drugs are used to relieve pain, swelling and other symptoms of inflammation, including arthritis
and joint pain. Some peptic ulcers are caused by taking these NSAIDs. Omeprazole Sandoz is used to treat and help prevent
ulcers developing which are associated with long term NSAID use.
Omeprazole Sandoz is also used to treat a rare condition called Zollinger-Ellison syndrome, where the stomach produces very
large amounts of acid, much more than in ulcers and reflux disease.
Ask your doctor if you have any questions about why this medicine was prescribed for you.
Your doctor may have prescribed it for another reason.
How Omeprazole Sandoz works
Omeprazole Sandoz belongs to a group of medicines called proton pump inhibitors (PPIs).
It works by decreasing the amount of acid made by the stomach, to give relief from the 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.
