Ranitidine is used to treat heartburn, ulcers, GERD, acid reflux and other conditions relating to the production of excess stomach acid.
Ranitidine is commonly known by the brand name Zantac, but it’s now available from many different brands. It helps by blocking stomach cells that produce acid so that you don’t experience the symptoms of too much acid.
Ranitidine is available in many formulations, each with different dosage requirements. Depending on your version and what you’re treating, it might be taken whenever you need it or on an ongoing basis.
