Zegerid OTC (generic: omeprazole and sodium bicarbonate) is an over-the-counter medication used to treat heartburn that occurs 2 or more days a week.
Zegerid OTC belongs to a group of drugs called proton pump inhibitors, which work by lowering the amount of acid in your stomach that would cause heartburn. Sodium bicarbonate is a salt that protects omeprazole from stomach acid.
This medication comes in capsule form and is usually taken once a day at least 1 hour before eating in the morning.
