Summary

Duloxetine inhibits CYP2D6, which contributes to oliceridine metabolism, so oliceridine exposure may increase and cause greater sedation and respiratory depression. Both drugs also have serotonergic activity, adding a possible risk of serotonin syndrome.

What this interaction means in plain words

Duloxetine and Oliceridine can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.

Duloxetine belongs to Central Nervous System; Oliceridine belongs to Musculoskeletal.

Evidence level: Moderate

Why it happens

CYP2D6 inhibition by duloxetine plus additive serotonergic and CNS depressant effects.

What to do

Monitor closely for respiratory depression, sedation and serotonin syndrome, and titrate oliceridine to effect with lower or less frequent doses. Reassess the oliceridine dose if duloxetine is stopped.
