Serotonin syndrome
Extremely high levels of serotonin or activation of certain serotonin receptors can cause a condition known as serotonin syndrome, with toxic and potentially fatal effects. In practice, such toxic levels are essentially impossible to reach through an overdose of a single antidepressant drug, but require a combination of serotonergic agents, such as an SSRI with a MAOI, which may occur in therapeutic doses. However, serotonin syndrome can occur with overdose of certain serotonin receptor agonists, like the NBOMe series of serotonergic psychedelics.
