{"This patient is predicted to be a CYP2D6 intermediate metabolizer and may be at an increased risk of a atomoxetine-related adverse events. Initiate with a dose of 0.5 mg/kg/day and if no clinical response and in the absence of adverse events after 2 weeks, consider obtaining a plasma concentration 2-4 h after dosing. If response is inadequate and concentration is <200 ng/ml, consider a proportional dose increase to achieve a concentration to approach 400 ng/ml. If unacceptable side effects are present at any time, consider a reduction in dose. Please consult a clinical pharmacist for more information."}
