PEPCID® is the original brand with the active ingredient famotidine which is a histamine-2 blocker (H2 blocker) that provides relief for occasional heartburn.
PEPCID® offers three main products that provide relief of occasional heartburn 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 15-30 minutes and helps control acid all day or all night.* PEPCID Complete® combines an H2 blocker with an antacid that starts neutralizing acid in your stomach in seconds, so it works even faster. Because the faster it starts relieving heartburn, the better.
*Begins to work in 15 to 30 minutes. †Based on 9-hour acid control studies during the day and 12-hour acid control studies during the night. Acid control does not imply symptom relief. ‡PEPCID AC® and Maximum Strength PEPCID AC® can prevent heartburn when taken 15 to 60 minutes before a meal.
