What is Zegerid?
Zegerid contains a combination of 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.
Zegerid is 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.
Zegerid is not for immediate relief of heartburn symptoms.
Zegerid contains sodium bicarbonate, a form of salt. Tell your doctor if you have Bartter's syndrome (a rare kidney disorder), or if you are on a low-salt diet.
The omeprazole found in Zegerid can cause kidney problems. Tell your doctor if you are urinating less than usual, or if you have blood in your urine.
Diarrhea may be a sign of a new infection. Call your doctor if you have diarrhea that is watery or has blood in it.
You may be more likely to have a broken bone while taking Zegerid long term or more than once per day.

Heartburn can mimic early symptoms of a heart attack. Get emergency medical help if you have chest pain that spreads to your jaw or shoulder and you feel anxious or light-headed.
Zegerid contains sodium bicarbonate, a form of salt. Each capsule contains the equivalent of 300 mg of sodium. Each packet of powder contains the equivalent of 460 mg of sodium. If you are on a low-sodium diet, you may not be able to use Zegerid. Talk with your doctor.

You may be more likely to have a broken bone in your hip, wrist, or spine while taking a proton pump inhibitor long-term or more than once per day. Talk with your doctor about ways to keep your bones healthy.
