What is Omeprazole?

Omeprazole is a generic drug used to treat certain conditions where there is too much acid in the stomach. It is used to treat gastric and duodenal ulcers, erosive esophagitis, and gastroesophageal reflux disease (GERD). GERD is a condition where the acid in the stomach washes back up into the esophagus.

Omeprazole is a proton pump inhibitor (PPI). It works by decreasing the amount of acid produced by the stomach.

What is Losec?

Losec is the branded version of Omeprazole. Omeprazole is medically equivalent to Losec but is available at a lower price.

How To Take

One tablet daily. Try to take omeprazole at the same time each day to avoid missing any doses. The usual dose is once a day in the morning.


Antacids taken as required. Antacids are alkali liquids or tablets that can neutralise the stomach acid. A dose may give quick relief. There are many brands, which you can buy. You can also get some on prescription. If you have mild or infrequent bouts of dyspepsia you may find that antacids used as required are all that you need.

Most people who take acid reflux medication do not have any side effects. However, side effects occur in a small number of users. The most common side effects are:
Nausea (feeling sick)
Abdominal (tummy) pain

For a full list of possible side effects and cautions, see the patient information leaflet.
