What is Carafate® (sucralfate) used for?

Carafate® is an anti-ulcer medication.

Carafate® is not greatly absorbed into the body through the digestive tract. It works mainly in the lining of the stomach by adhering to ulcer sites and protecting them from acids, enzymes, and bile salts.

Carafate® is used to treat an active duodenal ulcer. Sucralfate can heal an active ulcer, but it will not prevent future ulcers from occurring.

Carafate® may also be used for purposes not listed in this medication guide.
