What is often the first-line treatment for uncomplicated urinary tract infections?

The first-line treatment for uncomplicated urinary tract infections (UTIs) is often trimethoprim-sulfamethoxazole. This antibiotic combination is effective against many of the typical pathogens responsible for UTIs, particularly Escherichia coli, which is the most common causative organism. Trimethoprim-sulfamethoxazole is favored for uncomplicated cases due to its efficacy, relatively low cost, and the fact that it is generally well-tolerated by many patients.

Ciprofloxacin, although effective for UTIs, is typically reserved for more complicated cases or when first-line agents cannot be used due to resistance or patient-specific factors, as fluoroquinolone use is associated with more significant side effects and concerns about increasing resistance.

Nitrofurantoin is another effective option for uncomplicated UTIs, especially when the causative organism is sensitive, but it is not always the first choice due to potential renal issues in patients with reduced kidney function, among other considerations.

Fosfomycin is effective as well, particularly in single-dose treatments, but it is used less frequently as a first-line agent in comparison to trimethoprim-sulfamethoxazole. Thus, trimethoprim-sulfameth
