Bactrim DS contains a combination of sulfamethoxazole and trimethoprim, two antimicrobial agents that work together to inhibit bacterial growth through complementary mechanisms. This synergistic action enhances effectiveness against a broad range of susceptible bacteria.

Bactrim DS is widely used for the treatment of urinary tract infections (UTIs), respiratory tract infections, certain gastrointestinal infections, skin and soft tissue infections, and other bacterial conditions as determined by a healthcare professional.

The double-strength formulation provides a higher concentration of active ingredients per tablet, allowing convenient dosing in many treatment protocols.

Treatment decisions, dosage schedules, and duration of therapy should always be determined by a qualified healthcare professional.
