Pepcid belongs to a class of medications called H2-antagonists. It is used to treat stomach and duodenal (intestinal) ulcers, gastroesophageal reflux disease (GERD), and conditions where too much stomach acid is secreted, such as Zollinger-Ellison syndrome. It works by reducing the amount of acid secreted by the stomach.
Take Pepcid exactly as prescribed by your doctor. The usual adult dose is 20 mg or 40 mg at bedtime to 20 mg or 40 mg twice daily, depending on the condition being treated. This medication can be taken with or without food. The dose for treatment of duodenal ulcer is 40 mg at bedtime for 4 to 8 weeks. The usual dose for treatment of benign stomach ulcer is 40 mg once a day at bedtime for 4 to 8 weeks. For Zollinger-Ellison syndrome and similar conditions, the dose varies with the individual patient, but often starts with 20 mg every 6 hours. When used to relieve the symptoms of GERD or prevent GERD from returning, the usual dose is 20 mg twice daily. The maximum dose is 40 mg every 24 hours. Do not take it in this manner for more than 2 weeks.
Before taking Pepcid you should talk with your doctor if you have kidney or liver disease, stomach cancer, asthma, chronic obstructive pulmonary disease. Avoid drinking alcohol.
