Bactrim DS, a combination of sulfamethoxazole and trimethoprim, is a prescription antibiotic used to treat various bacterial infections. It is particularly effective for conditions such as urinary tract infections (UTIs), bronchitis, and certain types of pneumonia. Bactrim DS is available in a double-strength formulation, typically containing 800 mg of sulfamethoxazole and 160 mg of trimethoprim, which allows for convenient dosing. Bactrim DS is prescribed for both adults and children aged two months and older. It is effective against a range of infections, including middle ear infections and traveler’s diarrhea. The medication works by inhibiting bacterial folic acid synthesis, which is essential for bacterial growth and reproduction. The typical dosage for adults is one Bactrim DS tablet taken every 12 hours for 10 to 14 days, depending on the type of infection being treated. It is crucial to complete the full course of the antibiotic to prevent the development of antibiotic-resistant bacteria. In summary, Bactrim DS is a versatile antibiotic that plays a significant role in treating various bacterial infections, but it is essential to be aware of its potential side effects and adhere to prescribed dosages.
