Skønt mulige in vivo- interaktioner mellem docetaxel og anden samtidig administreret medicin ikke er undersøgt formelt, har in vitro- interaktions - studier med kraftigt proteinbundne stoffer såsom erythromycin, difenhydramin, propranolol, propafenon, fenytoin, salicylat, sulfamethoxazol og natriumvalproat, ikke påvirket docetaxels proteinbinding.
Although the possible in vivo interaction of docetaxel with concomitantly administered medication has not been investigated formally, in vitro interactions with tightly protein-bound agents such as erythromycin, diphenhydramine, propranolol, propafenone, phenytoin, salicylate, sulfamethoxazole and sodium valproate did not affect protein binding of docetaxel.
