What is Pepcid®?

PEPCID® is a Histamine-2 blocker (H2 blocker) with the active ingredient famotidine. Famotidine helps relieve heartburn by reducing the amount of acid in the stomach.

PEPCID® offers three main products that provide heartburn relief that you can take whenever you need. Original Strength PEPCID AC® and Maximum Strength PEPCID AC® contain an H2 blocker that begins to work in 15 minutes and helps control acid all day or all night.* PEPCID Complete® combines an H2 Blocker with an antacid that starts neutralizing acid in seconds, so it works even faster. Because the faster it starts relieving heartburn, the better.
