How long does Polymyxin B Sulfate and Trimethoprim Sulfate stay in your body?

The elimination half-life of polymyxin b sulfate and trimethoprim sulfate is about 8 to 10 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 in adults with normal kidney function, so trimethoprim is largely cleared in roughly 2 days (about 5 half-lives). Trimethoprim is not a prodrug and has no active metabolite that outlasts it — only 10-20% is metabolized (mostly in the liver to inactive oxide and hydroxy derivatives), and the free (unchanged) drug is the therapeutically active form, with the rest excreted unchanged in urine. Because clearance is mainly renal, the half-life lengthens in people with severely impaired kidney function, which calls for dose adjustment or avoiding the drug. Half-life is a clearance measure, not a drug-test detection window.

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.
