How does this medication work? What will it do for me?

Ranitidine belongs to the class of medications called H2-antagonists. It works by reducing the amount of acid secreted by the stomach in order to reduce ulcer and heartburn pain or to assist in healing of ulcers.

Ranitidine is used to treat and prevent stomach ulcers caused by non-steroidal anti-inflammatory drugs (NSAIDs); to prevent bleeding caused by stress ulcers for very ill people; to prevent a second episode of bleeding in the digestive tract caused by bleeding ulcers; and to prevent inhalation of stomach acid during surgery, for people who are considered at risk of this complication.

It is used to treat stomach and duodenal (intestinal) ulcers, and prevent them from recurring. It is also used to treat gastroesophageal reflux disease (GERD) and Zollinger-Ellison Syndrome.

This medication may be available under multiple brand names and/or in several different forms. Any specific brand name of this medication may not be available in all of the forms or approved for all of the conditions discussed here. As well, some forms of this medication may not be used for all of the conditions discussed here.

Your doctor may have suggested this medication for conditions other than those listed in these drug information articles. If you have not discussed this with your doctor or are not sure why you are taking this medication, speak to your doctor. Do not stop taking this medication without consulting your doctor.

How should I use this medication?

The recommended adult dose of ranitidine ranges from 150 mg daily to 150 mg twice daily or 300 mg once daily depending on the condition being treated. The maximum dose is 300 mg daily for most conditions. Ranitidine may be taken with or without food.

When treating Zollinger-Ellison syndrome, the dose of ranitidine varies, but is often higher than the doses used to treat ulcers. Doses larger than 300 mg daily are often needed.
