Drugs that have restrictions other than prior authorization, quantity boundaries, and phase therapy affiliated with Each and every prescription.
pentazocine decreases effects of fentanyl by pharmacodynamic antagonism. Stay clear of or Use Alternate Drug. Coadministration of mixed agonist/antagonist and partial agonist opioid analgesics may well cut down fentanyl's analgesic effect And maybe precipitate withdrawal symptoms.
Monitor Closely (one)ferric maltol, fentanyl. Either increases levels from the other by unspecified interaction mechanism. Modify Therapy/Monitor Intently. Coadministration of ferric maltol with certain oral medications may possibly minimize the bioavailability of both ferric maltol and a few oral drugs.
isocarboxazid raises toxicity of fentanyl by Other (see comment). Contraindicated. Remark: Prevent fentanyl in patients who demand concomitant administration MAOIs, or within 14 times of stopping an MAOI. Severe and unpredictable potentiation by MAO inhibitors has been reported with opioid analgesics.
Voxelotor improves systemic exposure of sensitive CYP3A4 substrates. Prevent coadministration with sensitive CYP3A4 substrates with a slim therapeutic index. Consider dose reduction of the delicate CYP3A4 substrate(s) if struggling to keep away from.
The effectiveness of buprenorphine or methadone in reducing abuse of fentanyl by humans is likewise mostly unknown. Experiments performed in rats have demonstrated that upkeep on buprenorphine was considerably less effective in reducing the analgesic effects of opioid agonists with decrease efficacy (morphine) in comparison with higher efficacy (etonitazene; Walker and Young, 2001). A analyze also was conducted in rhesus monkeys comparing the reinforcing effects of various opioid agonists from the presence and absence of morphine Actual physical dependence (e.g., Winger and Woods, 2001). Through the mechanism of cross-tolerance, 1 would anticipate a rightward shift inside the dose-effect curves for opioids when animals are physically depending on morphine in comparison to no dependence. Although this outcome was demonstrated for most of the agonists tested, the rightward shift during the dose-effect curve for that higher efficacy agonist alfentanil was smaller than to the intermediate efficacy agonists, morphine and heroin. Along with the dose-effect curves with the lessen efficacy agonists had been shifted both downward (buprenorphine) or rightward to the much larger extent (nalbuphine) than the higher efficacy agonists (Winger and Woods, 2001).
fentanyl, dexchlorpheniramine. Both improves toxicity of the other by pharmacodynamic synergism. Modify Therapy/Observe Carefully. Coadministration of fentanyl with anticholinergics could enhance risk for urinary retention and/or extreme constipation, which may result in paralytic ileus.
Significant - Use Choice (one)etravirine will lessen the level or effect of fentanyl by affecting hepatic/intestinal enzyme CYP3A4 metabolism. Stay clear of or Use Alternate Drug. Coadministration of fentanyl with CYP3A4 inducers could lead on to some lower in fentanyl plasma concentrations, not enough efficacy or, possibly, growth of a withdrawal syndrome inside of a client that has produced physical dependence to fentanyl.
If not able to stay away from coadministration of belzutifan with delicate CYP3A4 substrates, consider increasing the delicate CYP3A4 substrate dose in accordance with its prescribing information.
isavuconazonium sulfate will boost the level or effect of fentanyl by affecting hepatic/intestinal enzyme CYP3A4 metabolism. Use Caution/Monitor.
If coadministration of CYP3A4 inhibitors with fentanyl is essential, fentanyl trafficking data observe patients for respiratory depression and sedation at frequent intervals and consider fentanyl dose changes until eventually stable drug effects are realized.
fentanyl, brompheniramine. Both boosts toxicity with the other by pharmacodynamic synergism. Modify Therapy/Monitor Intently. Coadministration of fentanyl with anticholinergics may perhaps maximize risk for urinary retention and/or critical constipation, which may lead to paralytic ileus.
oxcarbazepine will minimize the level or effect of fentanyl by affecting hepatic/intestinal enzyme CYP3A4 metabolism. Modify Therapy/Monitor Intently. Coadministration of fentanyl with CYP3A4 inducers could lead on to the lessen in fentanyl plasma concentrations, not enough efficacy or, probably, improvement of a withdrawal syndrome in a individual who may have developed Actual physical dependence to fentanyl.
fentanyl and fentanyl intranasal both equally maximize sedation. Steer clear of or Use Alternate Drug. Restrict use to patients for whom alternative treatment options are insufficient
