In autopsy cases in which citalopram together with other substances was considered to be the cause of death, the concentrations of citalopram ranged from 0.6 to 5.2 mg/kg whole blood. In autopsy cases toxic concentrations ranged from 0.4 to 0.9 mg/kg whole blood and therapeutic concentrations from 0.03 to 0.6 mg/kg whole blood.
