Sulfamethoxazole-trimethoprim (SMX-TMP), commonly sold as Bactrim or Septra, effectively treats various bacterial infections. It’s a first-line treatment for uncomplicated urinary tract infections (UTIs), including cystitis and pyelonephritis. This combination targets a broad range of gram-positive and gram-negative bacteria, making it useful in treating acute exacerbations of chronic bronchitis.
Other Infections Treated by SMX-TMP
Beyond UTIs and bronchitis, SMX-TMP effectively combats traveler’s diarrhea caused by Escherichia coli and other susceptible pathogens. It is also frequently prescribed for skin infections like cellulitis and abscesses, though appropriate drainage might be necessary in the case of abscesses. Pneumocystis pneumonia (PCP), a serious opportunistic infection affecting individuals with weakened immune systems, particularly those with HIV/AIDS, responds well to SMX-TMP prophylaxis and treatment. However, clinicians should always consider resistance patterns and patient-specific factors when selecting this antibiotic.
