What is Voxzogo

Voxzogo contains the active ingredient vosoritida. It is similar to a protein present in the body called C-type natriuretic peptide (CNP). Vosoritida is produced through recombinant technology in which modified bacteria are used that include the gene that produces the protein.

How is Voxzogo used

This medication is used for the treatment of achondroplasia in patients 4 months of age and older whose bones are still growing. Achondroplasia is a genetic disease that affects the growth of almost all the bones in the body, including the bones of the skull, spine, arms, and legs, resulting in a significantly reduced stature with a characteristic appearance.

This product is only indicated for achondroplasia caused by the FGFR3 gene mutation, confirmed by genetic testing.

How Voxzogo works

The active ingredient of Voxzogo acts directly on the growth points of the bones to promote the growth of new bone.

Do not use Voxzogo

• if you or your child are allergic to vosoritida or any of the other components of this medication (listed in section 6).

Warnings and precautions

Consult your doctor before starting to use Voxzogo:

• if you or your child are taking or have recently taken medications to lower blood pressure.

If any of the above cases apply to you or your child or if you have doubts, consult your doctor before using Voxzogo.

Effects on blood pressure
