What is Bactrim primarily used to treat?

Bactrim, which is a combination of sulfamethoxazole and trimethoprim, is primarily used to treat urinary tract infections (UTIs). This antibiotic is particularly effective against a variety of bacterial pathogens that commonly cause UTIs, such as Escherichia coli.

While it may have some efficacy against certain strains of MRSA (Methicillin-resistant Staphylococcus aureus), this is not its primary or most common use. Bactrim is also not effective against viral infections, as it targets bacterial processes. Streptococcus infections may be treated with other classes of antibiotics rather than Bactrim specifically, as the efficacy can vary based on the specific strain and site of infection.

In summary, Bactrim is most recognized for its role in treating urinary tract infections due to its effectiveness in targeting the pathogens responsible for these infections.
