Sucralfate

Supportive Care

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

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.

Symptoms of an allergic reaction include: rash, hives, itching, chills, fever, headache, muscle ache, shortness of breath, coughing, tightness in the throat, swelling of the face or neck.

Not all patients who take sucralfate will experience these side effects. Common side effects are bolded, but there may be others. Please report all suspected side effects to your doctor or pharmacist.
