Objective: 

Physicians frequently prescribe allopurinol for uric acid deposition disorders. However, reports have emerged of the inappropriate use and over prescription of allopurinol. We conducted this study to determine the rate of inappropriate prescription of allopurinol in a Saudi institution.

Material(s) and Method(s):

This cross-sectional descriptive study was conducted on all adult patients who had been prescribed allopurinol in Doctor Soliman Fakeeh Hospital, Jeddah, Saudi Arabia. Demographic data and laboratory results were retrieved from patients’ electronic health records (EHR). We considered valid indications of allopurinol as significant hyperuricemia (>13 mg/dL in men and >10 mg/dL in women), confirmed gout, hyperuricosuria of more than 1100 mg/day, uric acid stones or recurrent calcium oxalate kidney stones, malignancy, and haemolysis. The possible valid indications were unconfirmed gout and unconfirmed type of kidney stones, whereas no documented indication or insignificant hyperuricemia was considered as an invalid indication.

Result(s):

We included 1978 patients in this study. The cohort was composed of 76.4% men and 23.6% women. The mean±standard deviation of age of this patient cohort was 53 and 4 months ± 15 years. The mean±standard deviation of duration since the first prescription was 1.53±2.2 years. Physicians prescribed allopurinol without a valid indication in 1539 patients (77.8%). More than a third of the patients (39%) did not have a documented indication and 38.8% were prescribed allopurinol for insignificant.

Conclusion(s):

This study revealed a markedly high number of allopurinol prescriptions without a clear indication in our centre. This approach may potentially expose patients to serious side effects of allopurinol without added benefits.
