Zantac is used for treating certain conditions that cause your body to make too much stomach acid (eg, Zollinger-Ellison syndrome). It is also used to treat ulcers of the small intestine that have not responded to other treatment. It may be used as a short-term alternative to oral ranitidine, in patients who are not able to take medicine by mouth. Zantac is an H2-receptor blocker. It works by blocking the action of histamine in the stomach. This reduces the amount of acid the stomach makes. Reducing stomach acid helps to reduce heartburn, heal irritation of the esophagus, and heal ulcers of the stomach or intestines.
Use Zantac as directed by your doctor.
- Do not take Zantac in larger amounts, or take it for longer than recommended by your doctor.
- You may take antacids while you are using Zantac if you are directed to do so by your doctor.
- Continue to use Zantac even if you feel well. Do not miss any dose.
- If you miss a dose of Zantac, use it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not use 2 doses at once.
Ask your health care provider any questions you may have about how to use Zantac.
