High Risk: Serotonin syndrome risk from combined serotonergic action
Tramadol has serotonergic activity in addition to its opioid effects, and SSRIs increase serotonin availability by blocking its reuptake. Used together they can raise synaptic serotonin to levels associated with serotonin syndrome, which can present with agitation, muscle twitching, tremor, high body temperature and autonomic instability.
