Side Effects of Carafate (Sucralfate)
Introduction to Carafate (Sucralfate)
Carafate, also known by its generic name sucralfate, is a medication primarily used to treat peptic ulcer disease. It works by forming a protective barrier on the ulcer site, neutralizing local acidity, and inhibiting the action of pepsin and bile salts 12.
Common Side Effects of Carafate
Constipation
One of the most frequently reported side effects of Carafate is constipation. This occurs in approximately 3-4% of patients taking the medication 12. The reason for this side effect is not fully understood, but it is likely related to the drug's limited absorption and its action within the gastrointestinal tract.
Xerostomia (Dry Mouth)
Another side effect that some patients experience is xerostomia, or dry mouth. This side effect is less common, affecting about 1% of users 12. Xerostomia can be uncomfortable and may lead to difficulties in speaking, eating, and swallowing.
Skin Eruptions
Skin eruptions, such as rashes, are also reported but are quite rare, occurring in only about 0.6% of patients 12. These skin reactions are generally mild and do not usually require discontinuation of the medication.
Absorption and Excretion
Carafate is minimally absorbed into the bloodstream, with only 3-5% of the orally administered dose being absorbed. The majority of the drug, over 90%, is excreted unchanged in the feces 12. This limited absorption contributes to its relatively low incidence of systemic side effects.
Drug-Drug Interactions
Notably, Carafate has no reported drug-drug interactions, making it a safer option for patients who may be on multiple medications 12.
Conclusion
Carafate is a unique and effective treatment for peptic ulcer disease with a favorable safety profile. The most common side effects include constipation, xerostomia, and skin eruptions, all of which are relatively rare and generally mild. Its minimal absorption and lack of drug-drug interactions further enhance its safety for short-term use.

Sucralfate given as a once daily enema does not significantly reduce the incidence of acute radiation proctitis symptoms and its routine clinical use cannot be recommended.
