Contraindicated. Coadministration not recommended; powerful cytochrome P450 enzyme inducers lower systemic publicity to roflumilast and should lessen the therapeutic efficiency
Stay away from; coadministration with CYP3A inducers could lead to reduced plasma concentrations of elvitegravir and/or simply a concomitantly administered protease inhibitor and result in loss of therapeutic outcome also to achievable resistance

Watch Closely (one)phenobarbital will reduce the level or impact of fentanyl transdermal by affecting hepatic/intestinal enzyme CYP3A4 metabolism. Modify Therapy/Check Closely. Coadministration of fentanyl with CYP3A4 inducers may lead to your minimize in fentanyl plasma concentrations, deficiency of efficacy or, perhaps, development of a withdrawal syndrome in a very patient that has formulated Actual physical dependence to fentanyl.
Check Closely (one)phenobarbital will reduce the extent or result of exemestane by affecting hepatic/intestinal enzyme CYP3A4 metabolism. Use Warning/Keep track of. For patients obtaining exemestane by using a potent CYP3A4 inducer the proposed dose of exemestane is 50 mg daily after a food.
Exclusive Affected person Population – Dosage ought to be lowered during the aged or debilitated because these patients may very well be a lot more sensitive to barbiturates. Dosage needs to be decreased for people with impaired renal purpose or hepatic illness.
phenobarbital will lessen the extent or outcome of paclitaxel protein sure by Other (see remark). Use Warning/Watch. Paclitaxel concentrations/efficacy may lessen when coadministered with CYP2C8 inducers Insignificant (one)phenobarbital will lessen the level or impact of paclitaxel protein bound by affecting hepatic/intestinal enzyme CYP3A4 metabolism.
