Ref: Therapeutic Range:
200 - 2600 ng/mL
Toxic Range:
Thioridazine, Toxic side effects can begin at levels of 1000 mcg/L
Mesoridazine, Not established.
The Thioridazine therapeutic range and toxic range overlap one another significantly. Accidental overdosage has resulted in death at levels greater than 1000 mcg/L whereas in chronic usage psychiatric patients tolerate levels as high as 2600 mcg/L.
