We report a case of severe serotonin syndrome after self-poisoning wit
h two antidepressant drugs, paroxetine (a selective inhibitor of serot
onin reuptake) and moclobemide (a reversible inhibitor of MAO-A). The
serotonin syndrome is characterized by neuromuscular, behavioural, and
autonomic changes. It occurs with the use of drugs able to increase s
erotonergic transmission in brain by acting on biosynthesis, reuptake,
catabolism or release of serotonin. Treatment is symptomatic, The inc
idence of severe cases seems to have increased, probably due to the us
e of new antidepressant ''specific'' inhibitors of the serotonin reupt
ake.
