metformin hydrochloride

How long does Metformin Hydrochloride stay in your body?

The elimination half-life of metformin hydrochloride is about 6.2 hours (plasma elimination half-life in adults with normal kidney function) — 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. Metformin is not metabolized and has no active metabolites, so 6.2 hours reflects the parent drug. The often-cited ~17.6-hour "blood" half-life reflects the drug lingering in red blood cells (distribution), not parent-drug elimination. The half-life is prolonged when kidney function is reduced.

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.
