How it works (mechanism)

Paroxetine is a potent CYP2D6 inhibitor + dual serotonergic effect.

Practical advice

Paroxetine affects how your body processes Tramadol, which may change its effectiveness. Your doctor may need to adjust dosages or consider an alternative. Do not change doses on your own.

Timing

Some opioids (tramadol, fentanyl, meperidine) have serotonergic activity and can cause serotonin syndrome with SSRIs. Take each at their prescribed times. Watch for agitation, rapid heartbeat, muscle rigidity, or confusion. Codeine and morphine are generally lower risk.

Risk factors

Higher risk with: liver impairment, genetic CYP enzyme variations (poor or ultra-rapid metabolizers), older age, polypharmacy (many medications).

Symptoms to watch for

Monitor for any unusual symptoms and report them to your healthcare provider promptly.
