Fosfomycin
About Fosfomycin
Fosfomycin is an oral antibiotic primarily prescribed to treat acute, uncomplicated urinary tract infections, such as bladder infections, in women. It works by targeting and killing the specific bacteria responsible for the infection, helping to clear the bladder and restore comfort. Because it concentrates quickly in the urine, it is highly effective at treating localised bladder issues.
This medication is unique because it is typically prescribed as a single, one-time dose. To ensure it works effectively, you should take it on an empty stomach, either 1 hour before or 2 hours after a meal, and preferably before bedtime after emptying your bladder. Drinking plenty of water during your recovery helps support your urinary system and naturally flushes out bacteria.
Most people tolerate this medication well, though some may experience mild, temporary digestive issues. If you notice severe, watery, or bloody diarrhoea or signs of an allergic reaction, you should stop taking it and contact your doctor immediately. Always consult your healthcare provider if your symptoms worsen or do not improve after a few days.
Do not take this if you have severe kidney damage or a known allergy to any of its ingredients. Before starting this medication, it is important to discuss your medical history with your doctor, especially if you have a history of digestive problems or food allergies.
Some medications, such as those that speed up digestion, can reduce the effectiveness of Fosfomycin by lowering its absorption in your body. If you are pregnant, planning a pregnancy, breastfeeding, or are an older adult, talk to your doctor or pharmacist to ensure this medication is safe and appropriate for your specific situation.

Patients Concern
Disease/Condition Glossary
Bladder infection: The most common type of urinary tract infection is a bladder infection. Bacteria enter the urethra, migrate to the bladder, and cause infections. Cloudy or bloody urine, urinating more frequently than usual, pain or burning when urinating, cramping or pressure in the lower back or lower abdomen, foul-smelling urine, or a frequent sensation of urge to urinate are all symptoms. Bladder infections can also result in mild back pain, which is linked to a kidney infection.
