The anticoagulant effects of warfarin are not affected by chlo-rdiazepoxide, diazepam, flurazepam, or nitrazepam, or the related hypnotics, eszopiclone, zaleplon, or zolpidem. The effects of phenprocoumon are not affected by nitrazepam or oxazepam, and those of ethyl biscoumacetate are not affected by chlo-rdiazepoxide. An interaction between any oral anticoagulant and a benzodiazepine is unlikely, but there are three unexplained and unconfirmed cases of increased or decreased anticoagulant responses, which were attributed to an interaction. 

In a study in healthy subjects, zaleplon 20 mg daily for 12 days had no effect on the AUC of 5- orR-warfarin after a single 25-mg dose of warfarin. There was a minor 17% increase in the maximum serum levels of5-war-farin. However, zaleplon did not alter the prothrombin time response to warfarin." "...
