Fosfomycin 3gm sachet is an antibiotic commonly used to treat uncomplicated urinary tract infections (UTIs), particularly caused by susceptible strains of bacteria like Escherichia coli. When administered as a single 3-gram dose, fosfomycin is generally well-tolerated and rapidly absorbed into the bloodstream and urinary tract.

In terms of efficacy, fosfomycin typically starts working within a short period, with noticeable improvement in UTI symptoms often observed within the first 24 to 48 hours after administration. However, complete resolution of symptoms may take several days, depending on the severity of the infection and individual patient factors.

Patients need to complete the full course of fosfomycin as prescribed by their healthcare provider, even if symptoms improve or resolve before completing the treatment. This helps ensure the eradication of the infection and reduces the risk of recurrence or development of antibiotic resistance.

Overall, fosfomycin 3g provides a convenient and effective option for the treatment of uncomplicated UTIs, with a rapid onset of action and a favorable tolerability profile. However, patients should always consult their healthcare provider for personalized advice and guidance regarding antibiotic treatment.
