Directions
Follow the directions for using this medicine provided by your doctor. SWALLOW WHOLE. DO NOT chew, crush, or open the capsule. If you have difficulty swallowing this medicine whole, the capsule may be opened and the contents sprinkled onto cool applesauce and taken as directed. Do not chew the food/medicine mixture or make-up a supply in advance. Doing so may destroy the drug and/or increase side effects. After taking the drug/applesauce mixture, drink a glass of cool water to ensure complete swallowing of the medicine. Take this medicine before a meal, unless otherwise directed by your doctor. This medicine may be taken with antacids if your doctor has instructed you to take antacids. Potent acid-reducing medicines such as omeprazole can decrease the effectiveness of sucralfate, as well as other drugs such as the antifungals ketoconazole and itraconazole. If instructed to take any of these medicines while taking omeprazole, consult your doctor or pharmacist regarding the proper timing of each dose. For example, if you are instructed to take sucralfate in addition to omeprazole, it is best to take the omeprazole at least 30 minutes before your sucralfate.
