How does this medication work? What will it do for me?
Ranitidine belongs to the class of medications called H2-antagonists. Ranitidine is used to reduce the amount of acid secreted by the stomach in order to reduce ulcer and heartburn pain or to assist in healing of ulcers. It is used to treat stomach and duodenal (intestinal) ulcers, and gastroesophageal reflux disease (GERD). Ranitidine is also used to prevent ulcers in certain circumstances and to treat a condition associated with large amounts of stomach acid secretion known as Zollinger-Ellison syndrome.
The over-the-counter form of raniditine 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.

How should I use this medication?
The recommended adult dose of ranitidine ranges from 150 mg daily to 300 mg twice daily depending on the condition being treated. Ranitidine may be taken with or without food.
When used over-the-counter to treat acid indigestion, heartburn, or sour or upset stomach, the usual dose for adults and children 16 years of age or older is 75 mg to 150 mg taken when symptoms appear. If symptoms persist for more than 1 hour or return after 1 hour, you may take a second dose of the same strength. To prevent symptoms brought on by consuming food or beverages, take the dose 30 to 60 minutes before eating food or drinking beverages that are expected to cause symptoms. The maximum dose is 300 mg every 24 hours. Do not take it in this manner for more than 2 weeks without seeking medical advice.
Injection: The injectable form of raniditine may be used in hospitals under specific circumstances when the patient is not able to swallow tablets. The usual dose of ranitidine injection is 50 mg every six to eight hours given intravenously (into a vein) or intramuscularly (into a muscle).
