etravirine will decrease the level or effect of fentanyl by affecting hepatic/intestinal enzyme CYP3A4 metabolism. Keep away from or Use Alternate Drug. Coadministration of fentanyl with CYP3A4 inducers may lead to your lower in fentanyl plasma concentrations, insufficient efficacy or, probably, development of a withdrawal syndrome inside a patient that has designed Bodily dependence to fentanyl.
mitotane will minimize the level or effect of fentanyl by affecting hepatic/intestinal enzyme CYP3A4 metabolism. Modify Therapy/Check Closely. Coadministration of fentanyl with CYP3A4 inducers may lead into a minimize in fentanyl plasma concentrations, insufficient efficacy or, potentially, improvement of a withdrawal syndrome inside of a individual who may have made physical dependence to fentanyl.
isocarboxazid raises toxicity of fentanyl by Other (see remark). Contraindicated. Remark: Keep away from fentanyl in patients who need concomitant administration MAOIs, or within fourteen times of halting an MAOI.

benzhydrocodone/acetaminophen and fentanyl equally raise sedation. Stay clear of or Use Alternate Drug. Restrict use to patients for whom alternate treatment options are insufficient
nalbuphine decreases effects of fentanyl by pharmacodynamic antagonism. Avoid or Use Alternate Drug. Coadministration of mixed agonist/antagonist and partial agonist opioid analgesics may perhaps minimize fentanyl's analgesic effect And perhaps precipitate withdrawal symptoms.

If you might want to go to A&E, tend not to generate yourself. Get another person to generate you or call for an ambulance.
glycerol phenylbutyrate will reduce the level or effect of fentanyl by affecting hepatic/intestinal enzyme CYP3A4 metabolism. Use Caution/Keep an eye on. Glycerol phenylbutyrate is often a weak inducer of CYP3A4. Watch for diminished efficacy of CYP3A4 substrates which have a slender therapeutic index.
Use warning when picking dosage for an aged individual, generally setting up at lower finish of dosing vary, reflecting better frequency of diminished hepatic, renal, or cardiac functionality and of concomitant sickness or other drug therapy; because elderly patients tend to be more likely to obtain decreased renal function, care must be taken in dose range, and should be useful to watch renal function
