Rifampicin (rifampin) and possibly phenytoin, known potent enzyme inducers, have been seen to lower tacrolimus levels (see Tacrolimus + Ri-famycins , p.l083, and Tacrolimus + Phenytoin, p.1081), and the manufacturers suggest that carbamazepine, isoniazid and phenobarbital will interact similarly. However, note that there is little to suggest that isoniazid has a clinically significant effect on this isoenzyme.
