概要
Dicloxacillin has been reported to reduce the anticoagulant effect of vitamin K antagonists such as warfarin, and a similar effect is expected with phenindione. Loss of anticoagulation raises the risk of thromboembolism, and the INR may fall during treatment and rise again after the antibiotic is stopped.

Dicloxacillin and Phenindione can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.
なぜ起こるのか
Probable induction of hepatic enzymes by dicloxacillin increasing metabolism of the anticoagulant.
