  • What is Pepcid?

    Pepcid is a medicine that works by decreasing the amount of acid the stomach produces. It is used for the short-term treatment of active duodenal (first part of the upper intestine) and stomach ulcers, and for gastroesophageal reflux disease (GERD), a condition in which the acid contents of the stomach flow back into the esophagus.

    Pepcid is also prescribed for certain diseases that cause the stomach to produce excessive quantities of acid, such as Zollinger-Ellison syndrome.

    Pepcid is available for oral use as tablets or suspension. It is also available as an intravenous injection.

    The over-the-counter Pepcid AC products are used for relief and prevention of heartburn associated with indigestion and sour stomach.

  • What is the most important information I should know about Pepcid?

    Do not stop taking Pepcid without first talking to your doctor. It may take up to 8 weeks for an ulcer to heal.

    Pepcid may cause dizziness. This effect may be worse if you take it with alcohol or certain medicines. Do not drive or perform other possibly unsafe tasks until you know how you react to it.

    Notify your doctor if you have any symptoms of a bleeding ulcer, such as black, tarry stools or vomit that looks like coffee grounds.

    Do not take antacids within 1 hour of taking Pepcid. Antacids may decrease the effectiveness of Pepcid.

    You can help avoid heartburn and acid indigestion by not lying down soon after eating; keeping your weight down; quitting smoking or at least cutting down; and not eating just before bedtime.

    Avoid or limit caffeine, chocolate, fatty foods, and alcohol.

  • Who should not take Pepcid?

  • What should I tell my doctor before I take the first dose of Pepcid?

Also, talk to your doctor about your complete medical history, especially if you have kidney or liver disease; trouble or pain swallowing food; vomiting with blood, or bloody or black stools; had heartburn for more than 3 months; have heartburn with lightheadedness, sweating, or dizziness; chest pain or shoulder pain with shortness of breath, sweating, pain (to the arms, neck, or shoulders), or lightheadedness; frequent chest pain; frequent wheezing; unexplained weight loss; nausea or vomiting; or stomach pain.
