What are lansoprazole delayed-release capsules?

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

Lansoprazole delayed-release capsules are used in adults:

• for 4 weeks for the healing and symptom relief of duodenal ulcers. The duodenal area is the area where food passes when it leaves the stomach.
• with certain antibiotics to treat an infection called H. pylori. Sometimes H. pylori bacteria can cause duodenal ulcers. The infection needs to be treated to prevent ulcers from coming back.
• for continued healing of duodenal ulcers.
• for up to 8 weeks to heal stomach ulcers.
• for up to 8 weeks to heal stomach ulcers in some people taking pain medicines called non-steroidal anti-inflammatory drugs (NSAIDs).
• for reducing the risk of stomach ulcers in some people taking NSAIDs.
• for up to 8 weeks for the relief of heartburn and other symptoms of 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 8 weeks to heal the acid-related damage to the lining of the esophagus (called erosive esophagitis) and to relieve symptoms. If needed, your doctor may prescribe another 8 weeks of lansoprazole delayed-release capsules.
• for continued healing of erosive esophagitis.
• for the long-term treatment of conditions where your stomach makes too much acid. This includes a condition called Zollinger-Ellison syndrome.
