What is Allopurinol and What Does it Treat?
Allopurinol is a medication used to treat gout and kidney stones. It is also prescribed to people being treated with chemotherapy. Allopurinol belongs to the class of drugs known as xanthine oxidase inhibitors.

How Does Allopurinol Work?
Allopurinol works by reducing the concentration of uric acid in the body. This is accomplished by blocking xanthine oxidase enzymes, which the body uses to turn xanthine into uric acid.
Uric acid is a normal byproduct from the breakdown of purines. Typically, uric acid is dissolved in the blood and goes to the kidneys. From there it is expelled from the body with urine.
Allopurinol Dosage and Treatment
Allopurinol is usually taken as an oral tablet, once-a-day with food. It can also be injected (usually for chemotherapy patients).
Normal adults begin with one 100 mg tablet per day. This amount is increased until the desired uric acid level is attained. Typical doses for mild gout and kidney stones are 200 to 300 mg per day. For more severe cases of gout, 400 to 600 mg per day is more typical. The maximum dose is 800 mg.
Oral tablets that are taken for management of chemotherapy side effects usually contain higher doses of 600 to 800 mg per day.
Dosages might be adjusted for certain patients. Always follow the directions given by your doctor and the instructions on the prescription label.
