Intestinal ulcers are painful sores that develop in the inner lining of the intestine. Sucraneat Syrup is used to treat intestinal ulcers. Sucralfate Syrup works by reducing the amount of acid your stomach makes, preventing further damage to the ulcer, and heals naturally. Sucralfate Syrup also reduces pain and bleeding associated with intestinal ulcers. You may be given other medicines along with this medicine depending on what caused the ulcer. You need to keep taking Sucralfate Syrup as prescribed by the doctor for it to be effective, even if the symptoms seem to disappear.
