RANITIDINE (ra NYE te deen) is a type of antihistamine that blocks the release of stomach acid. It is used to treat stomach or intestinal ulcers. It can relieve ulcer pain and discomfort, and the heartburn from acid reflux.
This medicine is for injection into a muscle, or infusion into a vein. It is given by a health care professional in a hospital or clinic setting.
Talk to your pediatrician regarding the use of this medicine in children. Special care may be needed.
Side effects that you should report to your doctor or health care professional as soon as possible:
agitation, nervousness, depression, hallucinations
allergic reactions like skin rash, itching or hives, swelling of the face, lips, or tongue
breast enlargement in both males and females
redness, blistering, peeling or loosening of the skin, including inside the mouth
unusual bleeding or bruising
unusually weak or tired
yellowing of the skin or eyes
Side effects that usually do not require medical attention (report to your doctor or health care professional if they continue or are bothersome):
constipation or diarrhea
This does not apply.
This drug is given in a hospital or clinic and will not be stored at home.
They need to know if you have any of these conditions:
an unusual or allergic reaction to ranitidine, other medicines, foods, dyes, or preservatives
pregnant or trying to get pregnant
Tell your doctor or health care professional if your condition does not start to get better or gets worse. You may need to take this medicine for several days as prescribed before your symptoms get better.
Do not smoke cigarettes or drink alcohol. These increase irritation in your stomach and can lengthen the time it will take for ulcers to heal. Cigarettes and alcohol can also make acid reflux or heartburn worse.
If you need to take an antacid you should take it at least 1 hour before or 1 hour after this medicine. This medicine will not be as effective if taken at the same time as an antacid.
If you get black, tarry stools or vomit up what looks like coffee grounds, call your doctor or health care professional at once. You may have a bleeding ulcer.
