Zantac (Ranitidine)

Ranitidine or more commonly known to us as Zantac is a medication used for the treatment of gastro esophageal reflux disease (GERD), ulcers, and conditions where the stomach produces too much acid. Over the counter Ranitidine is used to treat and relive symptoms of heartburn. Zantac is in a class of medication that is called H2 blockers. It works by decreasing the amount of acid produced inside the stomach. Zantac may be used to treat other conditions; your doctor will have more information about these treatment options.

Take Zantac exactly as directed by your doctor or pharmacist.  Do not use Zantac to treat symptoms that your doctor is not aware of. Before taking Zantac tell your doctor if you are allergic to Ranitidine or any of the other ingredients in Zantac. Tell your doctor all medications and supplements that you are taking. These supplements and medications could cause adverse effect to your health.  Tell your doctor if you have kidney or liver disease. Also tell your doctor if you are pregnant, going to become pregnant or are breast feeding. If you become pregnant while taking Zantac contact your doctor.

If you miss a dose take it as soon as you remember. But if it is almost time for your next dose skip the missed one and continue on with your normal schedule. Do not take more than one dose to make up for a missed one.
