We report the case of a 22-year-old woman presenting major depressive episode with severe akathisia after an increase in fluoxetine. The patient developed severe restlessness and de novo suicidal ideation approximately 1 week after the dosage of fluoxetine was doubled, 1 year on from when the drug was first introduced. This case illustrates the importance of being alert to movement disorders in patients treated with selective serotonin reuptake inhibitors. The clinical implications are discussed. A management strategy based on the evidence in the existing literature is suggested.
