This information is intended solely for healthcare professionals:

The reconstitution of the solution must be performed at the time of intravenous administration.

Dissolve the content of the 1 g vial with the 10 ml of the solvent ampoule. Take the corresponding volume for the adequate dose. Dilute in water for injection preparations or glucose solution at a ratio of 4 ml per ml of the previously prepared solution. Place in a 1-hour infusion.

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