Keep track of Closely (1)lenacapavir will increase the level or effect of fentanyl by affecting hepatic/intestinal enzyme CYP3A4 metabolism.
Keep an eye on Closely (2)efavirenz will lower the level or effect of fentanyl by affecting hepatic/intestinal enzyme CYP3A4 metabolism. Modify Therapy/Observe Intently. Coadministration of fentanyl with CYP3A4 inducers could lead into a lower in fentanyl plasma concentrations, deficiency of efficacy or, probably, improvement of a withdrawal syndrome in a affected person who's got designed physical dependence to fentanyl.
After halting a CYP3A4 inducer, given that the effects of your inducer drop, the fentanyl plasma concentration will raise which could raise or prolong both of those the therapeutic and adverse effects.
olanzapine/samidorphan decreases effects of fentanyl by pharmacodynamic antagonism. Contraindicated. Samidorphan elicits opioid antagonistic effects and raises risk of precipitating acute opioid withdrawal in patients depending on opioids.
Keep an eye on Intently (1)telotristat ethyl will reduce the level or effect of fentanyl by affecting hepatic/intestinal enzyme CYP3A4 metabolism.
Repotrectinib is actually a CYP3A4 inducer. Steer clear of coadministration with CYP3A substrates where nominal concentration changes can cause minimized efficacy, Except otherwise recommended their prescribing information.
Keep away from use when taking any oral drug that is certainly dependent on threshold concentrations for efficacy. Interactions listed are representative illustrations and don't consist of all attainable clinical illustrations.

fentanyl will minimize the level or effect of prasugrel by inhibition of GI absorption. Applies only to oral type of equally agents. Modify Therapy/Monitor Carefully. Coadministration of opioid agonists hold off and lessen the absorption of prasugrel?
somapacitan will lessen the level or effect of fentanyl by affecting hepatic/intestinal enzyme CYP3A4 metabolism.
pentobarbital will decrease the level or effect of fentanyl by affecting hepatic/intestinal enzyme CYP3A4 metabolism. Modify Therapy/Keep an eye on Intently. Coadministration of fentanyl with CYP3A4 inducers could lead on to your fentanyl qu'est ce que c'est reduce in fentanyl plasma concentrations, deficiency of efficacy or, potentially, advancement of a withdrawal syndrome in the individual that has formulated Actual physical dependence to fentanyl.
If coadministration of CYP3A4 inhibitors with fentanyl is critical, keep track of patients for respiratory depression and sedation at frequent intervals and consider fentanyl dose changes until stable drug effects are obtained.
fentanyl will raise the level or effect of lemborexant by affecting hepatic/intestinal enzyme CYP3A4 metabolism. Modify Therapy/Keep track of Closely. Decreased nightly dose of lemborexant advised if coadministered with weak CYP3A4 inhibitors. See drug monograph for particular dosage modification.
Check Carefully (one)St John's Wort will decrease the level or effect of fentanyl by affecting hepatic/intestinal enzyme CYP3A4 metabolism. Modify Therapy/Monitor Carefully. Coadministration of fentanyl with CYP3A4 inducers could lead on to the decrease in fentanyl plasma concentrations, insufficient efficacy or, potentially, enhancement of the withdrawal syndrome in the affected individual who may have created Bodily dependence to fentanyl.
