RUCONEST addresses the root cause of HAE attacks

Most people with HAE don't have enough C1-INH

HAE is caused by not having enough of the blood protein called C1-INH, or by C1-INH that isn’t working properly.

RUCONEST works by increasing functional C1-INH levels in the blood into the normal range. RUCONEST also helps stop the production of kallikrein, an enzyme that activates bradykinin, which causes blood vessels to leak and certain parts of the body to swell.
