Summary
Combining tapentadol with the tricyclic antidepressant lofepramine can add to drowsiness and psychomotor impairment. Both drugs also have serotonergic activity, so serotonin syndrome and a lowered seizure threshold are possible, although lofepramine is less serotonergic than many other tricyclics.
What this interaction means in plain words
Lofepramine and Tapentadol 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.
Why it happens
Additive CNS depression and additive serotonergic and noradrenergic effects, with possible seizure threshold lowering.
What to do
Start with the lowest effective tapentadol dose and monitor for sedation, agitation, tremor, hyperreflexia or other serotonin toxicity signs. Advise patients to avoid driving until the response is known.
