The correct dosage and schedule for maintaining the serum uric acid within the normal range is best determined by using the serum uric acid as an index. Although a causal mechanism and a cause-and-effect relationship have not been established, current evidence suggests that renal function should be monitored in patients on thiazide diuretics and Allopurinol even in the absence of renal failure, and dosage levels should be even more conservatively adjusted in those patients on such combined therapy if diminished renal function is detected. If anorexia, weight loss, or pruritus develop in patients on Allopurinol, evaluation of liver function should be part of their diagnostic workup.

If progressive deposition of urates is to be arrested or reversed, it is necessary to reduce the serum uric acid level below the saturation point to suppress urate precipitation. Concurrent conditions such as multiple myeloma and congestive myocardial disease were present among those patients whose renal dysfunction increased after Allopurinol was begun. As a result of xanthine oxidase inhibition, the serum concentration of hypoxanthine plus xanthine in patients receiving Allopurinol for treatment of hyperuricemia is usually in the range of 0.3 mg/dL to 0.4 mg/dL compared to a normal level of approximately 0.15 mg/dL. It has been reported that symptoms may develop in approximately 1 week from initiating Allopurinol therapy, but longer latency periods have also been reported.

In transferring a patient from a uricosuric agent to Allopurinol, the dose of the uricosuric agent should be gradually reduced over a period of several weeks and the dose of Allopurinol gradually increased to the required dose needed to maintain a normal serum uric acid level. In those patients in whom renal insufficiency was documented, however, the recommendation to lower the dose of Allopurinol was not followed. Allopurinol oral tablet (Zyloprim) is an oral drug used to decrease uric acid levels. The incidence of skin rash may be increased in the presence of renal insufficiency.
