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.

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

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.

Postmarketing life-threatening cases of cardiac toxicity (including complete AV block, bradycardia, and cardiomyopathy), lactic acidosis, acute renal failure, CNS depression and respiratory complications leading to death have been reported, predominantly in preterm neonates receiving KALETRA oral solution.

Sedative/Hypnotics: triazolam, orally administered midazolam ↑ triazolam ↑ midazolam Contraindicated due to potential for prolonged or increased sedation or respiratory depression [see Contraindications ( 4 )] .

…potential risks, infants should be monitored closely for increases in serum osmolality and serum creatinine, and for toxicity related to KALETRA oral solution including: hyperosmolality, with or without lactic acidosis, renal toxicity, CNS depression (including stupor, coma, and apnea), seizures, hypotonia, cardiac arrhythmias and ECG changes, and hemolysis.

Analgesics Opioid: methadone* fentanyl Non-opioid analgesic (selective blocker of Na v 1.8 sodium channels): suzetrigine ↓ methadone ↑ fentanyl ↑ suzetrigine and active metabolite M6-SUZ Dosage of methadone may need to be increased when co-administered with KALETRA.
