Special Instructions: The therapeutic range of Tacrolimus is not clearly defined but target 12-hour trough; whole blood concentrations are 5 - 20 ng/mL early post-transplant. Higher concentrations are associated with an increased incidence of adverse effects. 24-hour trough concentrations are 33 - 50% less than the corresponding 12 hour trough levels. These target levels are for liver transplant only.
