RT Journal Article SR Electronic T1 What Is Allopurinol Failure and What Should We Do About It? JF The Journal of Rheumatology JO J Rheumatol FD The Journal of Rheumatology SP 556 OP 562 DO 10.3899/jrheum.2024-0144 VO 51 IS 6 A1 Stamp, Lisa K. A1 Dalbeth, Nicola YR 2024 UL http://www.jrheum.org/content/51/6/556.abstract AB Allopurinol is the most widely used urate-lowering medication worldwide. However, allopurinol failure is frequently observed in clinical practice. In this review, we provide a framework for assessing allopurinol failure, which includes failure of allopurinol to control serum urate concentrations, failure of allopurinol to control clinical symptoms, and failure of allopurinol due to an adverse drug reaction. Understanding the causes of allopurinol failure underpins the approach required to turn failure into success in gout management.
