Bactrim, an antibiotic containing sulfamethoxazole and trimethoprim, typically remains detectable in the bloodstream for about 24 to 48 hours after the last dose. However, the exact duration can vary based on individual metabolism, kidney function, and dosage. It's important to note that standard blood tests may not specifically test for Bactrim unless there is a reason to do so.
