MONUROL is only used to treat uncomplicated infections of the bladder in females. It works by killing bacteria which can cause infections. Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed it for another reason.

The active ingredient in MONUROL passes into breast milk and there is a possibility that your baby may be affected.

Taking other medicines

Tell your doctor or pharmacist if you are taking any other medicines, including any that you get without a prescription from your pharmacy, supermarket or health food shop.

Some medicines and MONUROL may interfere with each other. These include:

  • metoclopramide or other drugs that increase the movement of food through the stomach and intestines, because they may reduce the uptake of fosfomycin trometamol by your body
  • anticoagulants, as their ability to prevent your blood from clotting might be altered by fosfomycin trometamol and other antibiotics.
  • Urinary alkalinisers can alter the acidity of the urine and may interfere with how MONUROL works.

These medicines may be affected by MONUROL or may affect how well it works. You may need different amounts of your medicines, or you may need to take different medicines.

Your doctor and pharmacist have more information on medicines to be careful with or avoid while taking this medicine.
