phenobarbital ↔ hydrocodone

Applies to:belladonna/ergotamine/phenobarbital and Norco (acetaminophen/hydrocodone)

Consumer information for this interaction is not currently available.

MONITOR: Coadministration with enzyme-inducing anticonvulsants may decrease the plasma concentrations of opioids that are primarily metabolized by CYP450 3A4 such as fentanyl, hydrocodone, oxycodone, and sufentanil. Reduced efficacy or withdrawal symptoms may occur in patients maintained on their narcotic pain regimen following the addition of an enzyme-inducing anticonvulsant. By contrast, discontinuation of the anticonvulsant may result in a fatal overdose.

MANAGEMENT: Pharmacologic response to the opioid should be monitored more closely whenever an enzyme-inducing anticonvulsant is added to or withdrawn from therapy, and the opioid dosage adjusted as necessary. Ambulatory patients should be counseled to avoid hazardous activities requiring mental alertness and motor coordination until they know how these agents affect them, and to notify their physician if they experience excessive or prolonged central nervous system effects that interfere with their normal activities.
