IMPORTANT SAFETY INFORMATION

RUCONEST is contraindicated in patients with a history of allergy to rabbits or rabbit-derived products and for patients with a history of life-threatening immediate hypersensitivity reactions, including anaphylaxis, to C1 esterase inhibitor (C1-INH) preparations.

Monitor patients for early signs of allergic or hypersensitivity reactions (including hives, generalized urticaria, tightness of the chest, wheezing, hypotension, and/or anaphylaxis). If symptoms occur, discontinue RUCONEST and administer appropriate treatment.

Serious arterial and venous thromboembolic (TE) events have been reported with plasma-derived C1-INH products. Risk factors may include the presence of an indwelling venous catheter/access device, prior history of thrombosis, underlying atherosclerosis, use of oral contraceptives or certain androgens, morbid obesity, and immobility. Monitor patients with known risk factors for TE events during and after RUCONEST administration.

Appropriately trained patients may self-administer RUCONEST upon recognition of an HAE attack. Advise patients to seek medical attention if progress of any attack makes them unable to properly prepare or administer a dose of RUCONEST. No more than 2 doses should be administered within a 24-hour period.

The serious adverse reaction reported in clinical trials was anaphylaxis. The most common adverse reactions (incidence ≥2%) were headache, nausea, and diarrhea.

Before prescribing RUCONEST, please read the full Prescribing Information including the Patient Product Information.
