Long information

What is it and how is it used?

Ruconest contains conestat alfa as the active substance. Conestat alfa is a recombinant form of human C1inhibitor ( rhC1INH) and is produced using recombinant DNA technology from the milk of rabbits.

Ruconest is to be used by adults with a rare inherited blood disorder, called Hereditary Angioedema(HAE). These patients have a shortage of the C1 inhibitor protein in their blood. This can lead to repeated attacks of swelling, pain in the abdomen, difficulty breathing and other symptoms.

The administration of conestat alfa (Ruconest) is to resolve the shortage of C1 inhibitor and will lead to reduction of symptoms of an acute attack of HAE.
