التداخل بين هيدروكودون ونيفيرابين

In addition, discontinuation of a concomitantly used cytochrome P450 3A4 inducer may result in an increase in hydrocodone plasma concentration.

Concomitant use with CYP3A4 inhibitors (or discontinuation of CYP3A4 inducers) can result in a fatal overdose of hydrocodone.

Similarly, discontinuation of a CYP3A4 inducer, such as rifampin, carbamazepine, and phenytoin, in HYSINGLA ER treated patients may increase hydrocodone plasma concentrations and prolong opioid adverse reactions.

When using HYSINGLA ER with CYP3A4 inhibitors or discontinuing CYP3A4 inducers in HYSINGLA ER-treated patients, evaluate patients at frequent intervals and consider dosage reduction of HYSINGLA ER until stable drug effects are achieved [see Drug Interactions (7) ].

Concomitant use of HYSINGLA ER with CYP3A4 inducers or discontinuation of an CYP3A4 inhibitor could decrease hydrocodone plasma concentrations, decrease opioid efficacy or, possibly, lead to a withdrawal syndrome in a patient who had developed physical dependence to hydrocodone.

Other Agents Analgesics: Methadone ↓ Methadone Methadone levels were decreased; increased dosages may be required to prevent symptoms of opiate withdrawal.

Opiate Agonists: Fentanyl Plasma concentrations may be decreased.
