Allopurinol is an FDA -Approved xanthine oxidase inhibitor, which is effective in the
treatment of gout, hyperuricemia and uremic kidney stones in patients with an increased level of
uric acid excretion. Xanthine oxidase acts by converting hypoxanthine and xanthine into uric acid,
and therefore its inhibition results in decreased production of uric acid. The most common side effects
of this medication are as follows: maculopapular rashes, hives, itching, headache, dizziness,
abnormal hair loss, fever and hypersensitivity reaction.
