How long does Fexofenadine Hydrochloride stay in your body?

The elimination half-life of fexofenadine hydrochloride is about 14 hours (label: mean elimination half-life 14.4 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 elimination half-life measured in healthy adults on 60 mg twice daily. Fexofenadine is barely metabolized — the label says only about 5% of the dose is cleared by hepatic metabolism — and the label describes no active metabolite that outlasts the parent, so the parent's half-life is the whole story. (Fexofenadine is not a prodrug; it is itself the active moiety.) It takes longer to clear with impaired kidneys: the label reports mean elimination half-life 59% longer in mild-to-moderate renal impairment (creatinine clearance 41-80 mL/min), 72% longer in severe impairment (11-40 mL/min), and 31% longer in people on dialysis (CrCl 10 mL/min or less). Liver impairment does not change it — the label says pharmacokinetics in hepatically impaired subjects "did not differ substantially" from healthy subjects. In adults 65 and older, the half-life is similar to younger adults, though peak plasma levels are about 99% higher. This is a plasma-clearance figure, not a drug-test detection window and not dosing guidance.

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.
