1. What is Fosfocina and what is it used for
Fosfocina contains the active substance fosfomycin. It belongs to a group of medicines called antibiotics. It works by killing certain types of germs (bacteria) that can cause serious infectious diseases. Your doctor has decided to treat you with Fosfocina to help your body fight an infection. It is essential that you receive effective treatment for this condition.
Antibiotics are used to treat bacterial infections and are not effective against viral infections such as the flu or the common cold. It is essential that you follow the instructions regarding the dose, administration interval, and treatment duration indicated by your doctor. Do not store or reuse this medicine. If you have any leftover antibiotic after finishing the treatment, return it to the pharmacy for proper disposal. Do not throw away medicines via wastewater or household waste. |
Fosfocina is used in adults, adolescents, and children to treat infections caused by bacteria in:
- the urinary tract
- the heart, sometimes referred to as "endocarditis"
- the bones and joints
- the lungs, referred to as "pneumonia"
- the skin and tissues under the skin
- the central nervous system
- the abdomen
- the blood, when originating from any of the aforementioned conditions.

Other medicines and Fosfocina
Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines, including those bought without a prescription.
This is especially important if you are taking:
- anticoagulants, as fosfomycin and other antibiotics may alter your ability to prevent blood clotting.

Fosfomycin may pass to the baby in the womb or through breast milk. If you are pregnant or breastfeeding, your doctor will only prescribe this medicine when strictly necessary.

This information is intended only for healthcare professionals:
The reconstitution of the solution should be performed at the time of intravenous administration under aseptic conditions, using the following compatible solvents: saline solution for infusion (NaCl 0.9%), glucose solution 5% or 10% for infusion, or Ringer's lactate solution for infusion.
Dissolve the contents of the 8 g vial with 40 ml of solvent. Transfer to a container with 210 ml of solvent to obtain a total volume of 250 ml and administer by drip over 60 minutes.
When dissolving fosfomycin, an exothermic reaction occurs with the consequent release of heat, causing the vial to warm up slightly.
The reconstituted solution is clear and has a slightly yellowish color.
The physical-chemical stability of the reconstituted solution in the infusion bottle (low-density polyethylene with a polypropylene cap and an elastomer membrane) has been demonstrated for 24 hours at 25°C/60% RH with light and for 7 days at a temperature of 2°C - 8°C.
From a microbiological point of view, the solution should be used immediately after reconstitution/dilution. If not used immediately, the period and conditions of use before administration are the responsibility of the user and should not exceed 24 hours between 2 and 8°C, unless the method of dilution and reconstitution has been carried out under controlled and validated aseptic conditions.
In case of renal insufficiency, apply a dose reduction and an increase in administration time. For this, the following guideline can be applied:
ACrpatient | ACrpatient/ACrnormal | Recommended daily dosea |
40 ml/min | 0.333 | 70% (divided into 2-3 doses) |
30 ml/min | 0.250 | 60% (divided into 2-3 doses) |
20 ml/min | 0.167 | 40% (divided into 2-3 doses) |
10 ml/min | 0.083 | 20% (divided into 1-2 doses) |
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 Cockcroft-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 fosfomycin at the end of each dialysis session.
