sulfamethoxazole and trimethoprim double strength

How long does Sulfamethoxazole and Trimethoprim stay in your body?

The elimination half-life of sulfamethoxazole and trimethoprim is about 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. The FDA label states the mean serum half-life of sulfamethoxazole is 10 hours (co-formulated with trimethoprim, whose half-life is 8 to 10 hours). Half-life is prolonged in patients with severely impaired renal function, requiring dosage adjustment; the elderly, who often have reduced kidney function, may also clear it more slowly. Sulfamethoxazole is not a prodrug; it is partly metabolized to an inactive N-acetylated metabolite that does not outlast the parent. Half-life is not the same as a drug-test detection window — the drug can remain detectable longer than a single half-life implies.

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.
