How long does Ethinyl Estradiol and Norethindrone stay in your body?

The elimination half-life of ethinyl estradiol and norethindrone is about 8 hours — the time it takes the body to clear about half of it. As a rule of thumb, a medicine is mostly gone after roughly 4 to 5 half-lives, though this varies from person to person with age and kidney or liver function. This is the terminal (elimination) half-life, not a distribution phase: the label states "the mean terminal elimination half-life of norethindrone following single dose administration ... is approximately 8 hours," and its single-dose PK table gives t½ = 7.7 ± 0.5 hours (12 healthy women, 0.35 mg, fasting). Norethindrone itself is the active drug, and the label names no active metabolite that outlasts it — it is extensively reduced and then sulfate/glucuronide conjugated, with less than 5% excreted unchanged. Related point for anyone reading a different label: norethindrone ACETATE is a prodrug that is rapidly converted to norethindrone, so norethindrone is the active moiety in those products too. This label does not characterize how the half-life changes in older adults or in kidney or liver impairment — no such pharmacokinetic data is given, so no number can be quoted for those groups (the label does contraindicate use in women with significant liver disease, but that is a safety statement, not a half-life adjustment).

This is general information, not medical advice. It doesn’t tell you when a drug test would read negative (tests detect substances for different, often longer, windows) or when it’s safe to take another dose — ask your pharmacist or prescriber.
