Tapentadol inhibits noradrenaline reuptake and imipramine is a tricyclic that blocks serotonin and noradrenaline reuptake, so the combination raises the risk of serotonin syndrome and seizures. Additive sedation and CNS depression also occur.
What this interaction means in plain words
Imipramine and Tapentadol 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.

Why it happens
Additive serotonergic and noradrenergic reuptake effects with additive CNS depression; lowered seizure threshold from both drugs.
