Fluconazole and Oxycodone and acetaminophen interaction

Cytochrome P450 3A4 Interaction The concomitant use of oxycodone hydrochloride tablets with all cytochrome P450 3A4 inhibitors may result in an increase in oxycodone plasma concentrations, which could increase or prolong adverse reactions and may cause potentially fatal respiratory depression.

Monitor patients receiving Oxycodone Hydrochloride Tablets and any CYP3A4 inhibitor or inducer [see Warnings and Precautions ( 5.4), Drug Interactions ( 7), Clinical Pharmacology ( 12.3)] .

Risks of Concomitant Use or Discontinuation of Cytochrome P450 3A4 Inhibitors and Inducers Concomitant use of oxycodone hydrochloride tablets with a CYP3A4 inhibitor, such as macrolide antibiotics (e.g., erythromycin), azole-antifungal agents (e.g., ketoconazole), and protease inhibitors (e.g., ritonavir), may increase plasma concentrations of oxycodone and prolong…

When using Oxycodone Hydrochloride Tablets with CYP3A4 inhibitors or discontinuing CYP3A4 inducers in oxycodone hydrochloride tablets-treated patients, monitor patients closely at frequent intervals and consider dosage reduction of oxycodone hydrochloride tablets until stable drugs effects are achieved [see Drug Interactions ( 7)].

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