What is omeprazole and sodium bicarbonate?
Omeprazole is a proton pump inhibitor that decreases the amount of acid your stomach produces. Sodium bicarbonate is an antacid that raises the pH in your stomach to keep the omeprazole from breaking down in stomach acid.
Omeprazole and sodium bicarbonate is a combination medicine used to treat heartburn and other symptoms of gastroesophageal reflux disease (GERD). This medicine is also used to treat ulcers and other conditions involving excessive stomach acid production.
Omeprazole and sodium bicarbonate is not for immediate relief of heartburn symptoms.
Omeprazole and sodium bicarbonate may also be used for purposes not listed in this medication guide.
