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).

Zegerid is also used to treat certain type of ulcers, or to promote healing of erosive esophagitis (damage to your esophagus caused by stomach acid).

Zegerid is not for immediate relief of heartburn symptoms.

Warnings

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.

Omeprazole may cause new or worsening symptoms of lupus. Tell your doctor if you have joint pain and a skin rash on your cheeks or arms that worsens in sunlight.

You may be more likely to have a broken bone while taking this medicine long term or more than once per day.

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.

Before taking this medicine

You should not take Zegerid if you are allergic to omeprazole or sodium bicarbonate, or if:

• you have had breathing problems, kidney problems, or a severe allergic reaction after taking this medicine in the past; or

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-salt diet, you may not be able to use Zegerid. Talk with your doctor.

To make sure Zegerid is safe for you, tell your doctor or pharmacist if you have:

• a rare kidney disorder called Bartter''s syndrome;

• liver disease;

• any allergies;

• heart failure;

How should I take Zegerid?

Take Zegerid exactly as prescribed by your doctor. Follow all directions on your prescription label and read all medication guides or instruction sheets.

Zegerid is for short-term use only, usually 4 to 8 weeks. Erosive esophagitis may take longer to heal. Follow your doctor''s dosing instructions very carefully.

Take this medicine on an empty stomach, at least 1 hour before eating a meal.

Take the Zegerid capsule with a full glass of water. Do not use any other type of liquid or food. Swallow the capsule whole and do not crush, chew, break, or open it.

To use the powder form, open a packet and pour all of the powder into a small cup with 1 or 2 tablespoons of water. Do not use any other type of liquid. Stir and drink this mixture right away. Add a little more water to the glass, swirl gently and drink right away.

Do not use two 20-mg capsules to equal one 40-mg capsule. Do not use two 20-mg powder packets to equal one 40-mg powder packet. If you do not use the exact capsule or powder packet your doctor has prescribed, you may receive too much sodium bicarbonate.
