Summary

Valerian has sedative properties that may add to the CNS depression produced by oxymorphone. This may increase drowsiness, impaired psychomotor performance and, rarely, respiratory depression.

What this interaction means in plain words

Oxymorphone and Valerian can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.

Evidence level: Low

Why it happens

Additive sedation, probably via GABAergic activity of valerian constituents; evidence is limited.

What to do

Advise patients to avoid valerian while taking oxymorphone or to use it only with careful monitoring for excess sedation. Counsel against driving and alcohol use.
