🌿 What is Fosfomycin 3 g (Fosirol Powder)?

Fosirol Powder contains Fosfomycin Tromethamine, a broad-spectrum bactericidal antibiotic that inhibits bacterial cell wall synthesis by blocking the MurA enzyme. It is indicated for the treatment of uncomplicated UTIs, including cystitis in women.

A single 3 g oral dose achieves high urinary concentrations, maintaining bactericidal levels for 48–72 hours. This single-dose regimen enhances patient compliance and reduces resistance risk.

For full prescribing information and safety data, refer to the FDA label for Monurol and the Drugs.com monograph. Additional guidance is available via the NHS Medicines A–Z entry and the WHO Essential Medicines List.
