Quizplus · Accepted Answer

Allopurinol can inhibit hepatic drug-metabolizing enzymes and thus delay the inactivation of other drugs. This is a particular concern in patients taking warfarin; therefore, the warfarin dose should be reduced when allopurinol is also used. It is not correct to increase the allopurinol dose, increase the warfarin dose, or reduce the allopurinol dose.
