See "Severe side effects" in section 4.

Pregnancy and breastfeeding

Fosfomycin may pass into the body of the unborn child or into breast milk. The doctor will only prescribe this medicine to a pregnant or breastfeeding woman if it is clearly necessary.

One vial with 2 g of fosfomycin contains 28 mmol (640 mg) of sodium, one vial with 4 g of fosfomycin contains 56 mmol (1280 mg) of sodium, and one vial with 8 g of fosfomycin contains 111 mmol (2560 mg) of sodium.

3. How to take InfectoFos
InfectoFos is administered to the patient by a doctor or nurse intravenously (in the form of an intravenous infusion).
Dosage
The size and frequency of doses depend on:
- the type and severity of the infection,
- kidney function. In children, dosing also depends on:
- the child's body weight,
- the child's age. In cases of kidney problems or the need for dialysis, the doctor may need to reduce the dose of the medicine. Method and route of administration Intravenous administration. InfectoFos is administered to the patient by a doctor or nurse intravenously (in the form of an intravenous infusion). The infusion usually lasts 15-60 minutes, depending on the dose. The medicine is usually administered two, three, or four times a day.
Duration of treatment
The doctor will decide how long the treatment should last, depending on how quickly the patient's condition improves. During treatment of bacterial infections, it is important to complete the full treatment cycle. Even after the fever has subsided and the symptoms have improved, the treatment should be continued for several more days.
In the case of certain types of infections, such as bone infections, a longer treatment period may be required after the symptoms have subsided.
Taking a higher dose of InfectoFos than recommended
It is unlikely that the doctor or nurse will administer too high a dose of the medicine to the patient. If the patient thinks they have been given too high a dose of the medicine, they should ask them immediately.
If the patient has any further questions about the use of this medicine, they should ask their doctor, pharmacist, or nurse.
