Important information about 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.
  • If you miss a dose, take it as soon as you remember. If it is near the time of the next dose, skip the missed dose. Take your next dose at the regular time. Do not double the dose.

The most common side effects of Pepcid AC include:

  • Headache.
  • Lightheadedness.
  • Constipation.
  • Diarrhea.

Some individuals may experience serious side effects while using Pepcid AC. These side effects may require immediate medical attention. If you experience any of the following, contact your healthcare provider or seek emergency medical help:

  • Allergic reaction. Signs include hives, swelling of the tongue, face, or throat, and trouble breathing.
  • Brain-related side effects such as confusion, delirium, hallucinations (seeing things that aren't real), agitation, seizures, and weakness.

These are not all of the possible side effects of Pepcid AC. You should always seek medical advice from your healthcare provider for any questions or concerns about your medical condition or treatment. Read all patient information, medication guides, or drug information sheets that come with this medication. You can also report adverse effects to the Food and Drug Administration at www.fda.gov/medwatch or 1-800-FDA-1088.

Before starting Pepcid AC, it is crucial to discuss any existing health conditions with your healthcare provider. You should be sure that your healthcare provider is aware of all your medical conditions, including whether you have:

  • History of long QT syndrome.
  • Stomach cancer or other disorders.
  • Unexplained stomach pain or weight loss.

  • Heartburn for over 3 months, trouble or pain swallowing food, vomiting with blood, or bloody or black stools. These may be signs of a more serious condition.
  • Heartburn is frequently confused with the initial signs of a heart attack. Seek emergency medical assistance if you have chest pain or a heavy feeling, pain extending to your arm or shoulder, nausea, sweating, or a general sick feeling.

Severe allergy to another histamine-2 (H2) antagonist, famotidine, or any inactive ingredients in the product.
