Pepcid is used to treat and prevent heartburn, acid indigestion, sour stomach, gastroesophageal reflux disease (GERD), peptic ulcers, and conditions involving excessive stomach acid such as Zollinger-Ellison syndrome.
Pepcid works by blocking histamine-2 (H2) receptors in the stomach lining, which reduces the amount of acid the stomach produces. Lower acid levels help relieve symptoms and allow damaged tissue to heal.
Consult a healthcare provider before use if pregnant, breastfeeding, or taking other medications. Do not use for self-treatment if experiencing difficulty swallowing, bloody stools, or vomiting blood. Stop use and seek medical attention if symptoms persist beyond two weeks. May interact with certain medications including ketoconazole and atazanavir.
