1. What Monuril is and what it is used for

Monuril contains the active substance fosfomycin trometamol. Fosfomycin trometamol is an antibiotic that works by killing bacteria which can cause infections.

Monuril is used to treat or prevent uncomplicated infections of the bladder.

Monuril is not suitable for the treatment of children below 12 years of age.

2. What you need to know before you take Monuril

Do not take Monuril if you:

  • are allergic to fosfomycin trometamol or any of the other ingredients of this medicine (listed in section 6)
  • have severe kidney problems (creatinine clearance below 10 ml/min)
  • are undergoing haemodialysis.

Warnings and precautions

Talk to your doctor or pharmacist before taking Monuril if you have:

  • an allergic reaction during treatment (see section 4)
  • an intolerance to some sugars (see end of section 2)
  • previously had diarrhoea after taking any other antibiotics
  • kidney problems, but your creatinine clearance is above 10 ml/min.

Children and adolescents

Do not give this medicine to children less than 12 years of age, as its safety and efficacy have not been established in this age group.

Other medicines and Monuril

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines, including medicines obtained without a prescription.

This is especially important if you are taking:

  • 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.

Pregnancy, breast-feeding and fertility

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.

Pregnant women may be able to use fosfomycin trometamol if it is considered necessary.

Breast-feeding mothers can take a single oral dose of this medicine.

There are no known effects of fosfomycin trometamol on fertility.
