Famotidine is a prescription drug used to treat conditions like:

  • Gastroesophageal reflux disease (GERD)
  • Sores in the lining of the intestine and stomach ( stomach and intestinal ulcers)
  • Too much acid in the stomach due to tumors in the small intestine or pancreas (Zollinger-Ellison syndrome, multiple endocrine neoplasias)
  • Erosive esophagitis

Famotidine is a histamine H2-receptor antagonist or H2-blockers. It works by lowering the production of acid in the stomach. It blocks the histamine, a naturally-occurring chemical in the body that stimulates the stomach cells to produce too much acid. Blocking the action of histamine reduces the production of acid in the stomach. This helps treat and prevent intestinal and stomach ulcers and erosive esophagitis. It also reduces the symptoms of GERD such as heartburn, stomach pain cough and difficulty swallowing.

You can also buy Famotidine without a prescription. You can take the over-the-counter medication to prevent and treat heartburn due to sour stomach and acid indigestion caused by some drinks and food.
