> Serotonin syndrome is a serious and potentially fatal reaction that sometimes occurs when combining drugs that potentiate serotonin neurotransmission. It can even happen with one drug. The greatest risk is probably when combinating a MAOI with a SRI. One must be careful whenever two serotonergic drugs are given simultaneously. Even adding lithium to a SSRI can precipitate an episode.

Other signs and symptoms include confusion, delerium, agitation, elevated heart-rate and blood pressure, nausea, muscle rigidity and involuntary movements, exaggerated reflexes, extreme restlessness, tremors, incoordination, sweating, and hyperventillation.

> - ScottThanks for your response, Scott. My psychiatrist thinks this is what occured with me when the Risperidone was added to the Parnate. I had confusion, slurred speech (not realizing this), would forget what I was saying in the middle of a sentence (not realizing this), mild incoordination, and I suffered from nausea, fluctuating blood pressure, chills and mild fever, involutary movements, stiff muscles and soreness in muscles. I was away from home where no phone service was available including cell phones. I did not know what to do when the confusion got really bad. But since the Risperidone was added to help with sleep at night, I had been taking it only two weeks with increasing symptoms after increasing the dose from .25 to .5 mg in the p.m. I decided to stop the Risperidone, and this brought on almost immediate improvement with the exception of some residual restlessness and involuntary movements that I am told should resolve in another week.
My psychiatrist said he researched this (is at a top University and said he has never heard of this before-- with an MAOI and an antipsychotic but said it is possible since both deal with serotonin levels. Thanks for your input.
