Is Carafate Used for Acid Reflux?
Carafate can be used to treat esophageal ulcers.

According to the National institutes of Health, Carafate, or generic sucralfate, is an anti-ulcer medication used to treat stomach ulcers and duodenal ulcers. Carafate works by forming a protective coating on ulcer sites and protecting them from acid and enzymes so that healing can occur. Carafate might be used to treat esophageal ulcers caused by acid reflux disease.
