Zegerid (Omeprazole / Sodium Bicarbonate)

Omeprazole/sodium bicarbonate (Zegerid) reduces the amount of acid in the stomach. Omeprazole reduces the acid and the sodium bicarbonate (an antacid) raises the pH in the stomach to keep the omeprazole from breaking down in the stomach acid.

Zegerid is prescribed for GERD, erosive esophagitis, and, in some cases, the short-term treatment of active duodenal ulcer and benign gastric ulcer.
