What is Losec?

Losec is a medication that treats a variety of stomach conditions including heartburn, indigestion, acid reflux and stomach ulcers.

How does it work?

Losec contains omeprazole which is a proton pump inhibitor (PPI). Proton pumps are enzymes found in the stomach that aid in creating acids for food digestion. Losec inhibits the proton pumps so that less stomach acid is made. 

Is Losec suitable for me?

This medication can be taken by most adults. Children and babies can take it also if prescribed by a doctor.
