Use of allopurinol is the main method to reduce blood uric acid, the most important risk factor for gout (gout). Allpourinol is an anti-uric acid xanthine oxydase inhibitor used to reduce uric acid for most gout patients. Allopurinol is not an analgesic, so it is not recommended for patients with acute gout attacks. The drug is used regularly, long-term (lifelong) to keep blood uric acid level of the patient is normal, prevent the recurrence of acute phase gout, prevent kidney complications of gout.

Allergy to allergy is uncommon, accounting for only about 5% of people who use drugs and rare allergic reactions, but this is a very unfortunate thing of patients gout. When allergic, patients must stop allpourinol and need to take some alternative measures to reduce the progression of gout. If a mild allergy to allpourinol, the doctor may apply the method of desensitization (small, incremental) to the patient, if no allergy patients continue to take medication, if continued All patients will have to stop taking the drug. If severe allergy, patients will have to stop using allopurinol for life.
In addition, allopurinol should not be used concurrently with captopril, thiazide diuretics. These drugs increase the allergic potential of allopurinol. Concomitant use of allopurinol with beta-lactam antibiotics (including penicillins and cephalosporins) is recommended because allopurinol increases the allergic potential of these antibiotics.
