What is Famotidine for?

Famotidine belongs to a class of medications called histamine-2 blockers. It works by suppressing the secretion of stomach acid and hence can be used to treat several gastrointestinal disorders, including benign gastric and duodenal ulceration, gastroesophageal reflux disease (GERD), heartburn, and non-ulcer dyspepsia.

How to use it?

Famotidine can be taken orally. The adult dosages are as follows:

For the treatment of benign gastric and duodenal ulceration, you should take 40 mg once daily at night for 4 to 8 weeks. The maintenance dose is 20 mg once daily at night.

For the treatment of GERD, you should take 20-40 mg twice daily for 6 to 12 weeks. The maintenance dose is 20 mg twice daily.

For the treatment of heartburn or non-ulcer dyspepsia, you should take 10 mg once or twice daily.

For mild symptoms, Famotidine can be taken on an intermittent basis (as needed) 10-60 minutes before a meal that you expect to cause heartburn.

What are the side effects of Famotidine

Common side effects of Famotidine include diarrhoea, fatigue, and headache.
