Pepcid and Pepcid AC are both brand names for famotidine, a medication commonly used to reduce stomach acid and relieve symptoms of acid reflux, heartburn, and gastroesophageal reflux disease (GERD). While both medications contain the same active ingredient, famotidine, the main difference lies in the dosage and intended use. Understanding these differences can help you choose the right product for your needs. This article explores the key differences and similarities between Pepcid and Pepcid AC.
Definition of Pepcid
Pepcid is a prescription medication containing famotidine, a histamine-2 (H2) blocker that reduces stomach acid production.

Definition of Pepcid AC
Pepcid AC is an over-the-counter (OTC) version of famotidine, designed for short-term relief of heartburn and acid indigestion. The “AC” stands for “Acid Controller,” highlighting its role as a fast-acting solution to occasional acid-related symptoms.
