Zantac Dosage – How Much Should I Take?

Zantac Dosage

Zantac is a medication that is available over the counter and by prescription in stronger formulations. It is primarily used to relieve the symptoms of heartburn as they relate to the production of stomach acid. Excessive stomach acid can lead to gastrointestinal symptoms such as stomach bloating, abdominal pain and a burning sensation in the abdomen. And, it is one of the main causes of indigestion symptoms. The medication is also used in the treatment of other digestive conditions, and Zantac dosage varies depending on what it is being used for. The active ingredient in Zantac is ranitidine.

Ranitidine is a histamine H-2 receptor antagonist that is used to reduce the production of stomach acid. While mostly used for the treatment of gastric disorders like GERD and ulcers, ranitidine is also used sometimes in conjunction with other histamine medications for hives. The medication can also be used as a preventative tool alongside NSAIDS to prevent ulcers.

Normal Zantac dosage for the use of everyday heartburn symptoms or acid reflux or GERD is between 75mg and 150mg at the onset of symptoms in adults over 16 years of age. Each regular strength pill contains 75mg, and one or two can be taken at a time. If within an hour of symptom onset discomfort is still present, a second identical dose can be taken. However, within a 24 hour period, the maximum safe Zantac dosage is 300mg, regardless of when taken or in what combination. It is important to note that for regular usage of symptoms associated with heartburn and indigestion resulting from stomach acid production that using the product for more than two weeks is not advisable. A health care provider should be consulted should the regular need for Zantac fro symptom relief persist beyond fourteen days.

Zantac may be recommended as a means for peptic ulcer treatment. And, when indicated for this purpose and recommended by a health care professional, it is possible that the recommended Zantac dosage may change to amounts different from those typically employed to relieve everyday stomach bloating caused by heartburn. However, Drugs.com explains that for the treatment of a peptic ulcer, the dosage remains the same in most cases, with 300mg daily being the average. But, it is also important to note that while treating ulcers with 300mg daily in one dose of Zantac is commonplace, studies have shown that two smaller 100mg doses have proven to be just as effective in many instances.

For the maintenance of peptic ulcers and use during the course of healing, the dosage of Zantac that is often employed is 150mg daily, usually taken at bedtime. This daily 150mg Zantac dosage is the standard also for the treatment of benign gastric ulcers, as well as serving as a maintenance regimen for same during the healing process. Interestingly enough, this 150mg dosage is multiplied times 4 each day for the treatment of erosive esophagitis, but longer term maintenance of the condition limits the maximum dose to 150mg twice daily.

Dosage for babies and children is different from that for adults and is often based on body weight. Therefore the dosage of Zantac for babies can vary depending on the age and size of the child, as well as what the medicine is being used for. For the treatment of duodenal and gastric ulcers in children, the average dosage is between 2 to 4 mg/kg, with the maximum intake being 300mg per day. This dose is administered twice daily. For the maintenance of these ulcers, the Zantac dosage remains the same at 2 to 4 mg/kg twice daily, however the maximum intake is halved, with 150mg/day being the upper limit. Babies and children being treated for GERD may be given doses as high as 5 to 10 mg/kg per day in two divided doses, although studies are still being conducted to determine the safety of this application.

Because of the differences in appropriate dosage of this popular over the counter remedy, it is best to follow the package directions exactly, unless specifically advised otherwise by a health care provider. WebMD accounts that side effects of ranitidine include constipation, headaches and dizziness and it is likely that these side effects are more pronounced in higher dosages. As with any over the counter remedy, taking the smallest dose possible to provide symptom relief is advisable to reduce the risk of adverse side effects. And, children and infants should never be given Zantac unless under the instruction and care of a medical professional.
