Sucralfate is used to treat ulcers. It adheres to damaged ulcer tissue and protects against acid and enzymes so healing can occur.
This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.
Sucralfate comes as a tablet and liquid to take by mouth. It usually is taken four times a day, 1 hour before meals and at bedtime. Take sucralfate on an empty stomach, 2 hours after or 1 hour before meals. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take sucralfate exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Shake liquid sucralfate well before measuring doses.
This medicine must be taken regularly to be effective. It may take up to 8 weeks for ulcers to heal.
Sucralfate is also used to protect the stomach lining when taking aspirin and for mouth sores that occur with cancer chemotherapy. Talk to your doctor about the possible risks of using this drug for your condition.
