Indications

Omeprazole is prescribed for a short period of time – usually 4-8 weeks – to treat ulcers of the stomach and the first part of the small intestine that connects to the stomach (the duodenum). It is also effective in treating gastro-oesophageal reflux, the backward flow of stomach acid contents into the oesophagus (the tube that connects the mouth to the stomach).

It is prescribed for longer periods of time to treat patients with Zollinger-Ellison syndrome, a rare condition associated with a tumour that creates high levels of stomach-acid secretion.

In some cases, omeprazole is prescribed along with other medication (often two different antibiotics) to eradicate H. pylori, a cause of stomach ulcers. It is also registered for the short-term treatment of severe reflux oesophagitis in children older than 12 months.

For this drug to remain effective, it has to be taken regularly. An ulcer may recur when you stop treatment prematurely.

Omeprazole can mask the symptoms and may delay the diagnosis of stomach cancers. Possible malignancy should be excluded prior to the start of treatment.

How does omeprazole work?
