Brand Name(s): Zantac 300

This medication description is not meant for treatment prescription without the intervention of a specialist

Common Uses:

Zantac is used to treat and prevent ulcers in the stomach and intestines. It also treats conditions in which the stomach produces too much acid, such as Zollinger-Ellison syndrome. Zantac also treats gastroesophageal reflux disease (GERD) and other conditions in which acid backs up from the stomach into the esophagus, causing heartburn.

How to use:

The usual starting dose is 150 milligrams 2 times a day or 10 milliliters (2 teaspoonfuls) 2 times a day. Your doctor also might prescribe 300 milligrams or 20 milliliters (4 teaspoonfuls) once a day, after the evening meal or at bedtime, if necessary for your convenience. The dose should be the lowest effective dose. Long-term use should be reduced to a daily total of 150 milligrams or 10 milliliters (2 teaspoonfuls), taken at bedtime.

For children 1 month to 16 years of age, the recommended dosage for initial treatment is 2 to 4 milligrams per 2.2 pounds of body weight per day twice daily up to a maximum of 300 milligrams per day. For long-term maintenance of healing, the recommendation is 2 to 4 milligrams per 2.2 pounds of body weight once daily up to a maximum of 150 milligrams per day.

People with kidney problems, such as some older adults, typically are given a lower dose. During the therapy with Zantac, the doctor is also more likely to monitor your kidney function if you're over 65.

Warning and Precautions:

A stomach malignancy could be present, even if your symptoms have been relieved by Zantac. If you have kidney or liver disease, Zantac should be used with caution. If you have phenylketonuria, you should be aware that the effervescent tablets and granules contain phenylalanine. Remember that certain medicines, such as aspirin, and certain foods and drinks (e.g., citrus products, carbonated drinks, etc.) irritate the stomach and may make your problem worse.
Cigarette smoking tends to decrease the effect of H 2 -blockers by increasing the amount of acid produced by the stomach. This is more likely to affect the stomach's nighttime production of acid. While taking H 2 -blockers, stop smoking completely, or at least do not smoke after taking the last dose of the day.
Drinking alcoholic beverages while taking an H 2 -receptor antagonist has been reported to increase the blood levels of alcohol. You should consult your health care professional for guidance. Check with your doctor if your ulcer pain continues or gets worse.
