Cytochrome P450 3A4 Interaction The concomitant use of hydrocodone bitartrate and homatropine methylbromide with all cytochrome P450 3A4 inhibitors may result in an increase in hydrocodone plasma concentrations, which could increase or prolong adverse drug effects and may cause potentially fatal respiratory depression.

Avoid the use of hydrocodone bitartrate and homatropine methylbromide in patients taking a CYP3A4 inhibitor or inducer [see Warnings and Precautions (5.7) , Drug Interactions (7.2 , 7.3) ] .

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

Avoid the use of hydrocodone bitartrate and homatropine methylbromide in patients taking CYP3A4 inhibitors or inducers.

Avoid the use of hydrocodone bitartrate and homatropine methylbromide in patients who are taking a CYP3A4 inhibitor or inducer.

…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.
