Fosirol® contains fosfomycin trometamol 3 g, an antibiotic that works by blocking an early stage of bacterial cell wall formation. This mechanism differs from many other antibiotics, helping maintain activity against a wide range of susceptible urinary pathogens.

Fosfomycin is widely used as a single-dose treatment for uncomplicated urinary tract infections, particularly acute cystitis caused by susceptible bacteria. Due to its high urinary concentrations and convenient administration, it is frequently selected for patients requiring a simplified treatment regimen.

In integrative clinical practice, fosfomycin may also be considered by healthcare professionals as part of broader antimicrobial strategies when appropriate clinical indications exist.

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