It is being marketed by CSL Behring in Germany since more than 30 years and has also been approved and marketed in 20 European countries, United States, Argentina, Australia, Canada, Israel, Japan and South Korea.

This FDA approval made the Berinert available for HAE patients of all age groups and it became the first and the only approved therapy for HAE which is available for the patients below 12 years of age.
