What is sucralfate?

Sucralfate (also called Carafate®) is used to treat ulcers. It coats the stomach lining and protects it from stomach acid and enzymes so healing can occur. Sucralfate is available as a light pink, oblong, 1-gm tablet and a pink liquid suspension. Both are taken by mouth.

Possible side effects of sucralfate

  • Constipation
  • Gas
  • Stomach pain

These are the most common side effects, but there may be others. Please report all side effects to the doctor or nurse.

In case of a severe side effect or reaction, call the doctor, nurse, or pharmacist at 595-3300. If you are outside the Memphis area, dial toll-free 1-866-2STJUDE (1-866-278-5833), and press 0 once the call is connected.
