What condition does Famotidine treat?

Famotidine is a prescription used for the treatment of peptic ulcers and gastroesophageal reflux disease. This is in the class of medications called histamine-2 (H2) blockers. This prescription is supplied as a tablet for oral use. The Food and Drug Administration (FDA) has already approved this medication.

Histamine is a naturally occurring chemical that stimulates cells in the stomach to produce acid. H2 blockers inhibit the action of histamine on the cells, thus reducing the production of acid.

How does Famotidine work?

Famotidine works by blocking histamine H2 receptors that are found in the cells in the stomach lining. Histamine usually binds to this receptor that causes the cells to create stomach acid. By blocking the H2 receptors, this drug stops histamine from binding to them and stops the cells from making stomach acid.

Stomach acid is made in the stomach as a normal part of the digestive process. Commonly, the linings of the duodenum and stomach are protected by a layer that resists acid attack. On the other hand, if large amounts of stomach acid are formed or this layer is damaged, an ulcer could develop on the lining of the duodenum and stomach. This is called a peptic ulcer.

In GERD, this medication lessens the production of stomach acid. It stops extra acid from flowing back into the food pipe and can be used to get rid of heartburn symptoms accompanying by acid reflux. It also allows the esophagus to heal in reflux esophagitis. By decreasing the amount of acid in the stomach and duodenum, this drug relieves the symptoms of indigestion.

What is the recommended dosage for Famotidine?

Famotidine is to be taken by mouth. This is usually taken once or twice a day or as directed by your doctor. If you are taking this once a day, it is usually taken at bedtime. You may take each dose with or without a meal. The recommended dosage is based on your medical condition, age, and response to the treatment. You should take the right dose, not more or less.
