**It depends: amoxapine has an approximate 8 hour half-life while its main active metabolite has about a 30 hour half-life.**
Most of the parent drug declines quickly and is largely gone within about 1 to 2 days, but the 8-hydroxy metabolite can take several days to clear, often up to about 6 days based on five half-lives. Clearance varies with age, liver or kidney function, dose, and interacting medicines, which can lengthen how long drug effects or side effects last. Talk with your clinician before stopping or changing your dose. citeturn0search14turn0search0
Taking amoxapine consistently
Common questions
How long does Amoxapine stay in your system?
Amoxapine is eliminated based on its half-life and the half-life of its active metabolite. The parent drug has an average half-life near 8 hours, so most of it is reduced substantially within 1 to 2 days, while the 8-hydroxy metabolite has a longer half-life near 30 hours and may take up to about 6 days to clear from the body using the five half-life rule. Individual factors like liver or kidney impairment, older age, higher dose, and interactions with other drugs can extend this timeframe. If you have persistent side effects or plan to stop treatment, contact your clinician for guidance. citeturn0search14turn0search0
