Fosfomycin 3gm sachet is widely known for its quick and reliable action against urinary tract infections (UTIs), especially uncomplicated cases in women. It works by stopping the growth of harmful bacteria in the urinary system, helping relieve symptoms like burning, frequent urination, and lower abdominal discomfort. One of its biggest advantages is its convenience—most people only need a single 3-gram dose, making it far easier to take compared to longer antibiotic courses. The medication comes as a powder that you dissolve in water and drink on an empty stomach. Within a few hours, Fosfomycin begins fighting the infection, and many patients start feeling better within a day. Because it targets common UTI-causing bacteria like E. coli, it remains a trusted choice among doctors, especially when other antibiotics are ineffective.
