What happens if I take too much phenelzine?

An overdose of phenelzine is an emergency. A major issue is the potential for a life-threatening condition called serotonin syndrome. In serotonin syndrome, too much of the brain chemical (neurotransmitter) called serotonin is being released. Symptoms include sweating, rapid heart rate, vomiting and diarrhea. Other indications of an overdose include agitation, anxiety or even hallucinations.

If you think you took too much phenelzine, call 911 or get to an emergency room as quickly as possible.
