Omeprazole delayed-release suspension - oral
Omeprazole is used to treat certain stomach and esophagus problems (such as acid reflux, ulcers). It works by decreasing the amount of acid your stomach makes. It relieves symptoms such as heartburn, difficulty swallowing, and persistent cough. This medication helps heal acid damage to the stomach and esophagus, helps prevent ulcers, and may help prevent cancer of the esophagus. Omeprazole belongs to a class of drugs known as proton pump inhibitors (PPIs).
Read the Medication Guide provided by your pharmacist before you start taking omeprazole and each time you get a refill. If you have any questions, ask your doctor or pharmacist.
