Contraindicated. Coadministration not advised; robust cytochrome P450 enzyme inducers reduce systemic exposure to roflumilast and may reduce the therapeutic effectiveness
Watch Closely (1)phenobarbital will minimize the level or impact of tofacitinib by affecting hepatic/intestinal enzyme CYP3A4 metabolism. Use Warning/Watch. Lack of, or lessened reaction to tofacitinib may perhaps take place when coadministered with powerful CYP3A4 inducers
Recurring doses of charcoal with time may perhaps hasten elimination of some medicines which were absorbed. Safeguard the affected individual's airway when employing gastric emptying or charcoal.
