Ruconest is indicated for the treatment of acute angioedema attacks in patients with hereditary angioedema (HAE) due to C1 inhibitor deficiency. It is approved for use in adults and adolescents.

Ruconest contains conestat alfa, a recombinant form of human C1 esterase inhibitor. It works by inhibiting the activity of C1 esterase and kallikrein, which are involved in the inflammatory cascade that causes angioedema symptoms. This helps to control swelling and other symptoms during an acute attack.

Ruconest is administered by intravenous injection and should be used under medical supervision. It is not indicated for other forms of angioedema. Patients should discuss their complete medical history with their healthcare provider, including any history of thrombosis or hypersensitivity reactions, before starting treatment. As with all medications, use only as prescribed by a qualified healthcare professional.
