INDICATIONS Ranitidine 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. Ranitidine 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. INSTRUCTIONS  Use Ranitidine as directed by your doctor.  

• Do not take the medication in larger amounts, or take it for longer than recommended by your doctor. Follow the directions on your prescription label.
• You may take antacids while you are using Ranitidine if you are directed to do so by your doctor.
• Continue to use Ranitidine even if you feel well. Do not miss any dose.
• If you miss a dose of Ranitidine, 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 Ranitidine. STORAGE Store Ranitidine between 68 and 77 degrees F (20 and 25 degrees C). Brief storage at temperatures between 59 and 86 degrees F (15 and 30 degrees C) is permitted. Store away from heat, moisture, and light. Do not store in the bathroom. Keep Ranitidine out of the reach of children and away from pets.
