Pepcid AC Maximum Strength gives you 20 mg of Famotidine to relieve your heartburn daytime or nighttime. Famotidine is an acid reducer that can help with your heartburn symptoms that may include a burning feeling in your chest or throat, a hot, sour, or acidic taste at the back of your throat, especially when bending over or laying down.

Some people take Pepcid AC Maximum Strength 10-60 minutes before a meal to prevent the symptoms by reducing the production of stomach acid. If these symptoms persist or worsen, even when taking Pepcid AC Maximum Strength, see your doctor as you could have gastroesophageal reflux disease (GERD) that could cause damage to your esophagus.
