Interação entre Hidrocodona + paracetamol e Rifapentina

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

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

When adding CYP3A4 inhibitors or discontinuing CYP3A4 inducers in hydrocodone bitartrate and acetaminophen tablets-treated patients, evaluate patients at frequent intervals and consider dosage reduction of hydrocodone bitartrate and acetaminophen tablets until stable drug effects are achieved [see PRECAUTIONS, Drug Interactions ].

Concomitant use of hydrocodone bitartrate and acetaminophen tablets with CYP3A4 inducers or discontinuation of a 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.

When using hydrocodone bitartrate and acetaminophen tablets with CYP3A4 inducers or discontinuing CYP3A4 inhibitors, follow patients at frequent intervals and consider increasing the opioid dosage, if needed, to maintain adequate analgesia or if symptoms of opioid withdrawal occur [see PRECAUTIONS, Drug Interactions ].
