Typical 5 mg PO daily; 2.5 mg in elderly, low body weight, malnutrition, hepatic dysfunction. Genotype-guided initial dosing per CPIC/IWPC algorithms (CYP2C9, VKORC1, CYP4F2) is one of the most-established PGx applications in current practice (1)

routes: (Click arrow to add another value)
onset:

duration:
2-5 days after stopping (factor II resynthesis-limited) (1) ·
Analgesic effect 4-8 hours (much shorter than half-life would suggest, due to receptor kinetics); MOUD effect (opioid withdrawal suppression) 24-36 hours per single daily dose (1) ·
Depot IM 13 weeks (designed); often persists longer (1) ·
N/A (replacement) (2)
halflife:
