Cisapride

Cisapride is used to treat symptoms of nighttime heartburn in people who have not responded to other treatments.
Cisapride comes as a tablet and liquid to take by mouth. Cisapride usually is taken four times a day, 15 minutes before meals and at bedtime. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take cisapride exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Before taking cisapride,
tell your doctor and pharmacist if you are allergic to cisapride or any other drugs.
In addition to the medications listed in the important warning section, tell your doctor and pharmacist what prescription and nonprescription medications you are taking, especially antianxiety medications, anticholinergics (atropine, belladonna, benztropine, dicyclomine, diphenhydramine, isopropamide, procyclidine, and scopolamine), anticoagulants ('blood thinners') such as warfarin (coumadin), azithromycin (zithromax), cimetidine (tagamet), dirithromycin (dynabac), diuretics ('water pills'), miconazole (monistat), tranquilizers, and vitamins.
Tell your doctor if you have or have ever had intestinal disorders or bleeding ulcers.
Tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. If you become pregnant while taking cisapride, call your doctor.
