CPIC rec 8093961 [Optional]: Avoid tricyclic use due to potential lack of efficacy. Consider alternative drug not metabolized by CYP2D6. If a TCA is warranted, consider titrating to a higher target dose (compared to normal metabolizers). Titrate dose to observed clinical response with symptom improvement and minimal (if any) side effects. Utilize therapeutic drug monitoring to guide dose adjustments.

CPIC rec 8093977 [Optional]: Avoid tricyclic use due to potential for side effects. Consider alternative drug not metabolized by CYP2D6. If a TCA is warranted, consider a 50% reduction of recommended starting dose. Titrate dose to observed clinical response with symptom improvement and minimal (if any) side effects. Utilize therapeutic drug monitoring to guide dose adjustments. CPIC pair-level B (CYP2D6, CYP2C19 and Tricyclic Antidepressants) [PMID 23486447, 27997040] FDA labeling (Precautions)
