Abstract

<abstract abstract-type="main" id="jcpt12144-abs-0001"> <title>Summary</title> <sec id="jcpt12144-sec-0001" sec-type="section"> <title>What is known and objective</title> <p>Febuxostat is now recommended as the first‐line pharmacological urate‐lowering therapy for gout in the American College of Rheumatology guidelines. There is no case of rhabdomyolysis associated with febuxostat among reported side effects of the drug. Our objective is to report on a case of rhabdomyolysis associated with initiation of febuxostat in a patient with chronic kidney disease (CKD).</p> </sec> <sec id="jcpt12144-sec-0002" sec-type="section"> <title>Case summary</title> <p>A 73‐year‐old male patient visited our emergency room due to progressive weakness in both lower extremities starting 3 days earlier. Ten days before presentation, his primary physician had changed his prescription from allopurinol to febuxostat (80 mg) because of poor control of uric acid levels. There was tenderness in both thighs. Initial creatinine kinase (CK) was 7652 U/L (0–170 U/L), and a bone scan using <sup>99m</sup>Tc‐HDP revealed strong uptake in soft tissues in both thighs and buttocks. Electromyography (EMG) and nerve conduction velocity (NCV) showed abnormal spontaneous activities (ASA), suggesting myopathy, not nerve damage. On day 7 of admission, after conservative management and febuxostat withdrawal, he could walk on the ward. He is being followed in our clinic as an outpatient with no sequelae.</p> </sec> <sec id="jcpt12144-sec-0003" sec-type="section"> <title>What is new and conclusion</title> <p>This report is first case of rhabdomyolysis associated with initiation of febuxostat. Febuxostat should be withdrawn when rhabdomyolysis is confirmed.</p> </sec> </abstract>
