What are omeprazole delayed-release capsules?

Omeprazole delayed-release capsules are a prescription medicine called a proton pump inhibitor (PPI). Omeprazole delayed-release capsules reduce the amount of acid in your stomach.

Omeprazole delayed-release capsules are used in adults:

• for up to 8 weeks for the healing of duodenal ulcers. The duodenal area is the area where food passes when it leaves the stomach.
• with certain antibiotics for 10 to 14 days to treat an infection caused by bacteria called H. pylori. If needed, your doctor may decide to prescribe another 14 to 18 days of omeprazole delayed-release capsules by itself after the antibiotics. Sometimes H. pyloribacteria can cause duodenal ulcers. The infection needs to be treated to prevent the ulcers from coming back.
• for up to 8 weeks for healing stomach ulcers.
• for up to 4 weeks to treat heartburn and other symptoms that happen with gastroesophageal reflux disease (GERD). GERD happens when acid in your stomach backs up into the tube (esophagus) that connects your mouth to your stomach. This may cause a burning feeling in your chest or throat, sour taste, or burping.
• for up to 8 weeks to heal acid-related damage to the lining of the esophagus (called erosive esophagitis or EE). If needed, your doctor may decide to prescribe another 4 weeks of omeprazole delayed-release capsules.
• to maintain healing of the esophagus. It is not known if omeprazole delayed-release capsules are safe and effective when used for longer than 12 months (1 year) for this purpose.
• for the long-term treatment of conditions where your stomach makes too much acid. This includes a rare condition called Zollinger-Ellison Syndrome.

For children 2 to 16 years of age, omeprazole delayed-release capsules are used:

• for up to 4 weeks to treat heartburn and other symptoms that happen with gastroesophageal reflux disease (GERD).
• for up to 8 weeks to treat gastroesophageal reflux disease (GERD) with acid-related damage to the lining of the esophagus [called erosive esophagitis (or EE) due to acid-mediated GERD].
