Serum concentrations during and after 6-day administration of 5.6 mg/kg fluoxetine HCl s.c. or p.o. Concentrations steadily rise during administration and decline following cessation of treatment. Subcutaneous administration results in significantly higher serum concentrations. Both methods result in steady-state concentrations in the clinical range for humans. Dashed lines indicate the human clinical range.
