What Omeprazole RBX is used for
Omeprazole RBX tablets are used to treat peptic ulcers and also to help prevent them from coming back.
These ulcers can be caused by the stomach producing too much acid. Depending on the location of the ulcer it is called a gastric or duodenal ulcer. A gastric ulcer occurs in the stomach and a duodenal ulcer occurs in the tube leading out of the stomach, also known as the duodenum.
Peptic Ulcers associated with Helicobacter pylori infection
Most people with a peptic ulcer have been found to have the bacteria Helicobacter pylori in their stomach. Omeprazole RBX taken together with antibiotics will 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 known as non-steroidal anti-inflammatory drugs. These medicines are commonly taken to treat arthritis and other inflammatory conditions.
Omeprazole RBX can be used to heal and prevent ulcers associated with NSAIDs.
Omeprazole RBX is used to treat and prevent the symptoms of reflux oesophagitis.
This condition is caused by the washing back, or reflux, of food and acid from the stomach into the oesophagus. Symptoms include a burning sensation in the chest rising up to the throat, also known as heartburn.
Omeprazole RBX is also taken to help stop reflux oesophagitis coming back or relapsing.
Omeprazole RBX is used to treat this rare condition where the stomach produces excessive amounts of acid.
How Omeprazole RBX works
Omeprazole RBX belongs to a group of medicines called proton pump inhibitors. These medicines work 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 from being digested in the normal way.
Ask your doctor if you have any questions about why Omeprazole RBX has been prescribed for you. Your doctor may have prescribed Omeprazole RBX for another reason.
Omeprazole RBX is available only with a doctor's prescription.
There is no evidence that Omeprazole RBX is addictive.
