Pepcid AC

The active ingredient in Pepcid AC is famotidine. Famotidine is a histamine-2 blocker (H2 blocker), and it works by reducing the amount of stomach acid produced by certain cells in the stomach lining. Through this mechanism, famotidine results in acid control that reduces acid reflux and relieves heartburn symptoms.

Follow all directions given to you by your doctor and read all documents provided, including the full Prescribing Information, FDA-Approved Product Labeling, Instructions for Use, and Medication Guide, before using Pepcid AC. However, the following is a synopsis of the general guidelines for the use of Pepcid AC:

• The recommended dose of Pepcid AC for heartburn relief for adults and children 12 years old and over is typically 1 tablet by mouth with a glass of water.
• The recommended dose of Pepcid AC for heartburn prevention for adults and children 12 years old and over is 1 tablet by mouth with a glass of water 15 to 60 minutes before eating food or drinking.
• Do not chew, crush, or split the Pepcid AC famotidine tablet.
• Do not use more than 2 tablets in 24 hours.
