RANITIDINE (ra NYE te deen) is a type of antihistamine that blocks the release of stomach acid. It is used to treat stomach or intestinal ulcers. It can relieve ulcer pain and discomfort, and the heartburn from acid reflux.
Ranitidine has been withdrawn from the market due to safety concerns. The FDA recommends that you stop taking any oral syrup you currently have, dispose of it properly, and not buy more. Talk to your health care provider if you need advice about treatments.
This medicine may be used for other purposes; ask your health care provider or pharmacist if you have questions.
