About

What is Fosfomycin 3g?

Active ingredient: Fosfomycin · Dosages: 3 g sachet

Oral fosfomycin is an antibiotic used for selected acute, uncomplicated lower urinary tract infections. Fever, flank pain, pregnancy and recurrent infections can require a different assessment.

The indication, regimen and follow-up depend on your history and country guidance. A licensed doctor decides whether it is appropriate; prescribing is never automatic.

How it works in the body

It blocks an early step in bacterial cell-wall production and reaches high concentrations in urine.

How it helps

What it can offer when appropriate.

Short regimen when suitable

Uncomplicated cystitis in an eligible woman may be treated with one prescribed sachet.

Diagnosis checked first

The review looks for warning signs of kidney infection or a complicated UTI.

Antibiotic stewardship

It is prescribed only when symptoms, history and local guidance support it.

What to expect

A doctor-defined regimen.

A common regimen for eligible uncomplicated cystitis is one 3 g sachet dissolved in water and taken on an empty stomach.

Before treatment · Review symptoms and red flags
Dose · Dissolve the prescribed sachet and take it promptly
Follow-up · Seek review if symptoms persist or worsen

Typical regimen
