Uses

This medication is an antibiotic used to treat bladder infections (such as acute cystitis or lower urinary tract infections) in women. It works by stopping the growth of bacteria. This antibiotic treats only bacterial infections. It will not work for viral infections (such as common cold, flu). Using any antibiotic when it is not needed can cause it to not work for future infections.

Fosfomycin should not be used to treat infections outside the bladder (such as kidney infections).

How to Use This Medication

Read the Patient Information Leaflet if available from your pharmacist before you start taking fosfomycin. If you have any questions, ask your doctor or pharmacist.

Take this medication by mouth as directed by your doctor, usually 1 packet (sachet) as a single dose. Mix this drug with water before taking it. Pour the contents of 1 packet (sachet) into a half glass (4 ounces or 120 milliliters) of cold water and stir to dissolve. Do not use warm or hot water. Drink all of the mixture right away.

Your symptoms should get better within 2 to 3 days. Tell your doctor if you do not get better after 3 days or if you get worse.
