Zantac Injection

Who is Zantac Injection for ?

Your doctor has ordered Zantac Injection to decrease the acid produced by your stomach. Zantac Injection may be added to an intravenous fluid that will drip through a needle or catheter placed in your vein for 15 to 20 minutes, 1 to 4 times a day. It also may be added to your total parenteral nutrition (TPN) solution. Zantac Injection decreases acid in your stomach to help treat an ulcer or prevent one from developing. Zantac Injection helps to decrease the stomach pain, diarrhea, and loss of appetite that ulcers can cause. Zantac Injection is sometimes prescribed for other uses; ask your doctor or pharmacist for more information. Your health care provider (doctor, nurse, or pharmacist) may measure the effectiveness and side effects of your treatment using laboratory tests and physical examinations. It is important to keep all appointments with your doctor and the laboratory. The length of treatment depends on how you respond to Zantac Injection.

How does Zantac Injection work?

Zantac Injection is a histamine-2 receptor blocker, or H2-blocker. It works in the stomach on a pump that releases hydrochloric acid when stimulated by histamine. Zantac Injection prevents histamine from stimulating this pump, thereby reducing the amount of acid that is released into the stomach.
