Important Safety Information

Alpha1-Proteinase Inhibitor (Human), Zemaira® is indicated for chronic augmentation and maintenance therapy for adults with alpha1-proteinase inhibitor (A1-PI) deficiency and emphysema. Clinical data demonstrating the long-term effects of chronic augmentation therapy with Zemaira are not available.

Zemaira may not be appropriate for the following adult individuals as they may experience severe reactions, including anaphylaxis: individuals with a known hypersensitivity and/or history of anaphylaxis or severe systemic reaction to A1-PI products or their components, and individuals with selective IgA deficiencies who have known antibodies against IgA.

In clinical studies, the following treatment-related adverse reactions were reported in 1% of subjects: asthenia (fatigue), injection-site pain, dizziness, headache, paresthesia (tingling), and pruritus (itching).

Zemaira is derived from human plasma. The risk of transmission of infectious agents, including viruses and, theoretically, the Creutzfeldt-Jakob disease (CJD) agent, cannot be completely eliminated.
