How does this medication work? What will it do for me?
Famotidine 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.
The over-the-counter form of famotidine is used to treat conditions where a reduction of stomach acid is needed, such as acid indigestion, heartburn, or sour or upset stomach. It can also be used to prevent these symptoms when they are associated with eating food or drinking beverages, including nighttime symptoms.

As well, some forms of this medication may not be used for all of the conditions discussed here. If you have not discussed this with your doctor or are not sure why you are using this medication, speak to your doctor. Do not stop using this medication without consulting your doctor.
Do not give this medication to anyone else, even if they have the same symptoms as you do. It can be harmful for people to use this medication if their doctor has not prescribed it.

Tablets: The usual adult dose of famotidine tablets ranges from 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. Seniors and those with decreased kidney function may require lower doses or longer intervals between doses.
- The dose of famotidine for treatment of duodenal ulcer is 40 mg at bedtime for 4 to 8 weeks, or less if healing occurs. Therapy is often continued after healing of the ulcer at a dose of 20 mg once daily for up to 6 to 12 months.

- When used to relieve the symptoms of GERD or prevent GERD from returning, the usual dose is 20 mg twice daily. When used to treat esophageal damage related to GERD, the usual dose is 40 mg twice daily.
When used over-the-counter to treat acid indigestion, heartburn, or sour or upset stomach, the usual dose for adults and children 12 years of age or older is 10 mg to 40 mg once daily. To prevent symptoms brought on by consuming food or beverages, take the dose 10 to 15 minutes before eating food or drinking beverages that are expected to cause symptoms.
