Pepcid AC

Generic name: FamotidineBrand names: Pepcid AC, Pepcid

Why is Pepcid AC prescribed?

Pepcid is prescribed for the short-term treatment of active duodenal ulcer (in the upper intestine) for 4 to 8 weeks and for active, benign gastric ulcer (in the stomach) for 6 to 8 weeks. It is prescribed for maintenance therapy, at reduced dosage, after a duodenal ulcer has healed. It is also used for short-term treatment of GERD, a condition in which the acid contents of the stomach flow back into the food canal (esophagus), and for resulting inflammation of the esophagus. And it is prescribed for certain diseases that cause the stomach to produce excessive quantities of acid, such as Zollinger-Ellison syndrome. Pepcid belongs to a class of drugs known as histamine H2 blockers.

There are two over-the-counter forms of Pepcid. One version, Pepcid AC, is used to relieve and prevent heartburn, acid indigestion, and sour stomach. The other version, Pepcid Complete, also contains the antacids calcium and magnesium along with famotidine. Pepcid Complete is used to relieve heartburn, acid indigestion, and sour stomach but not for the prevention of symptoms.

Why should Pepcid AC not be prescribed?

Special warnings about Pepcid AC

If you have stomach cancer, Pepcid may relieve the symptoms without curing the disease. Your doctor will be careful to rule out this possibility.
