Opioid Antagonist naloxegol ↑ naloxegol Co-administration of PREZISTA/ritonavir and naloxegol is contraindicated due to potential for precipitating opioid withdrawal symptoms.

Sedatives/hypnotics: orally administered midazolam, triazolam ↑ midazolam ↑ triazolam Co-administration is contraindicated due to potential for serious and/or life-threatening reactions such as prolonged or increased sedation or respiratory depression.

Narcotic analgesics metabolized by CYP3A: e.g. fentanyl, oxycodone ↑ fentanyl ↑ oxycodone Careful monitoring of therapeutic effects and adverse reactions associated with CYP3A-metabolized narcotic analgesics (including potentially fatal respiratory depression) is recommended with co-administration. tramadol ↑ tramadol A dose decrease may be needed for tramadol…

Cytochrome P450 3A4 Interaction The concomitant use of Hydrocodone Polistirex and Chlorpheniramine Polistirex 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 Polistirex and Chlorpheniramine Polistirex 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 Polistirex and Chlorpheniramine Polistirex in patients taking CYP3A4 inhibitors or inducers.

Avoid the use of Hydrocodone Polistirex and Chlorpheniramine Polistirex in patients who are taking a CYP3A4 inhibitor or inducer.
