Serotonin syndrome is a syndrome that develops with the excessive stimulation of the serotonergic system. It may occur with the overdose usage of serotonergic drugs or of these drugs alongside with similar drugs. While only tremor and diarrhea are observed in its minor forms, in severe cases, this syndrome may lead to multiple organ failure and may be fatal. Generally it is a disorder practitioners may not consider and miss out especially when the case is a minor one. It has a wide symptom spectrum. As for its treatment, while minor cases may improve with backup treatment if diagnosed early and serotonergic drugs are discontinued, severe cases may require treatment under intensive care unit conditions. With this case report, I aim to present a case of serotonin syndrome occuring after a dose change of fluoxetine from 20 mg/day to 40 mg/day.
Key words: Serotonin Syndrome; Fluoxetine; Toxicity.
