Ranitidine (also called Zantac®) blocks the release of stomach acid. It is used to treat stomach ulcers. It can relieve the pain and discomfort caused by ulcers and heartburn associated with gastroesophageal reflux disease (also called GERD or acid reflux). Ranitidine is available in these forms:
- 75-mg and 150-mg peach-colored, film-coated, five-sided tablets taken by mouth
- A clear, peppermint-flavored liquid taken by mouth
- A clear liquid given by vein (IV)
Possible side effects
- Nausea and vomiting
- Feeling dizzy
- Feeling drowsy
- Temporary changes in liver function
These are the most common side effects, but there may be others. Please report all side effects to the doctor or nurse.
In case of a severe side effect or reaction, call the doctor, nurse, or pharmacist at 595-3300. If you are outside the Memphis area, dial toll-free 1-866-2STJUDE (1-866-278-5833), and press 0 once the call is connected.
- You may receive this drug when you are taking a steroid medicine called dexamethasone or prednisone. Steroids can sometimes irritate the stomach. Ranitidine may protect your stomach from this side effect.
- You may receive the IV form of ranitidine to add to your TPN fluid. Mix the dose that is ordered into the TPN fluid just before you use it. Discard the remaining rantidine in the vial each day. Ranitidine is stable for only 24 hours in the TPN fluid or in the vial.
- Ranitidine may affect the way other medicines work. These medicines include:
- Always tell your doctor if you are taking any of these medicines or if you start taking any new medicine while you are taking ranitidine.
- You can buy medicines similar to ranitidine (cimetidine and famotidine) without a prescription. Do not take these medicines while you are taking ranitidine without telling your doctor or pharmacist.
