How long does Methoxsalen stay in your body?

The elimination half-life of methoxsalen is approximately 2 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. The oral methoxsalen (PUVA) label reports a single "drug half-life is approximately 2 hours" without separating a distribution and a terminal phase, so 2 hours is the elimination half-life as stated. Detectable methoxsalen blood levels persist up to about 12 hours post-dose. The drug is rapidly metabolized, with roughly 95% excreted as metabolites in the urine within 24 hours; the label does not name any active metabolite that outlasts the parent, so photosensitivity is driven by the parent drug plus UVA exposure. The label does not state how the half-life changes with older age, kidney impairment, or liver impairment. This is a pharmacokinetic half-life, 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.
