This information is intended solely for healthcare professionals:

The reconstitution of the solution must be performed at the time of intravenous administration in aseptic conditions, using the following compatible solvents: saline solution for infusion (NaCl 0.9%), glucose solution for infusion at 5 or 10%, or Ringer Lactate solution for infusion.

Dissolve the contents of the 8 g vial with 40 ml of solvent. Pass to a container with 210 ml of solvent, to obtain a total volume of 250 ml, and put on a 60-minute infusion.

When dissolving fosfomicin, an exothermic reaction occurs with the consequent release of heat, causing the vial to warm slightly.

The reconstituted solution is clear and has a slightly yellowish color.

The physical-chemical stability of the reconstituted solution in the infusion bottle (of low-density polyethylene to which a polypropylene capsule with an elastomer membrane is added) has been demonstrated for 24 hours at 25°C/60% HR with light and for 7 days at a temperature of 2°C – 8°C.

From a microbiological point of view, the solution must be used immediately after reconstitution/dilution. If not used immediately, the storage and conservation period before use is the responsibility of the user and should not exceed 24 hours between 2 and 8°C, unless the dilution and reconstitution method has been carried out in controlled and validated aseptic conditions.

In the case of renal insufficiency, apply a dose reduction and an increase in administration time. To do this, the following dosage regimen can be applied:

aThe dose is expressed as a percentage of the dose that would have been considered adequate in the case of normal renal function of the patient, calculated according to the Cockgroft-Gault formula.

The first dose (loading dose) should be increased by 100%, but should not exceed 8 g.

Patients undergoing prolonged intermittent dialysis (every 48 hours) should receive 2 g of fosfomicin at the end of each dialysis session.
