1. What INFEUR is and what it is used for
INFEUR contains the active substance fosfomycin (as fosfomycin trometamol). It is an antibiotic that
works by killing bacteria that can cause infections.

section 6).
Warnings and precautions
Talk to your doctor, pharmacist or nurse before using INFEUR if you have any of the following
conditions:
- persistent bladder infections

Conditions you should be aware of

Children and adolescents

Other medicines and INFEUR
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 particularly important if you are taking:
- metoclopramide or other medicines that increase the movement of food through the stomach and intestine, as they may reduce the absorption of fosfomycin by your body;
- anticoagulants, since their ability to prevent blood clotting may be altered by fosfomycin and other antibiotics.
INFEUR with food
Food may delay the absorption of trometamol fosfomycin.
Therefore, this medicine should be taken on an empty stomach (2–3 hours before or 2–3 hours after a meal).
