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

Monitor patients receiving DEMEROL Injection and any CYP3A4 inhibitor or inducer [see Warnings and Precautions (5.5) , Drug Interactions (7) ] .

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

Risks of Concomitant Use or Discontinuation of Cytochrome P450 3A4 Inhibitors and Inducers Concomitant use of DEMEROL Injection 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 meperidine and prolong opioid…

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

…Lipid-modifying Agents: lomitapide, lovastatin, simvastatin Phosphodiesterase-5 (PDE-5) Inhibitor: sildenafil when administered as REVATIO ® for the treatment of pulmonary arterial hypertension Sedative/hypnotics: triazolam, orally administered midazolam Coadministration of GENVOYA is contraindicated with drugs that: Are highly dependent on CYP3A for clearance and for which…

Sedative/hypnotic: midazolam (oral) triazolam ↑ midazolam ↑ triazolam Coadministration with triazolam or orally administered midazolam is contraindicated due to potential for serious and/or life-threatening reactions such as prolonged or increased sedation or respiratory depression.

Dosage reduction for midazolam should be considered, especially if more than a single dose of midazolam is administered. buspirone zolpidem With other sedative/hypnotics, dose reduction may be necessary and clinical monitoring is recommended.

Other benzodiazepines: e.g., parenterally administered midazolam clorazepate diazepam estazolam flurazepam ↑ sedatives/hypnotics Triazolam and orally administered midazolam are extensively metabolized by CYP3A.

Narcotic Analgesics: buprenorphine/ naloxone ↑ buprenorphine ↑ norbuprenorphine ↓ naloxone No dosage adjustment of buprenorphine/naloxone is required upon coadministration with GENVOYA.
