Indications and Usage

Important Safety Information
wilate is contraindicated for patients who have known anaphylactic or severe systemic reaction to plasma-derived products, any ingredient in the formulation, or components of the container.
Hypersensitivity or allergic reactions have been observed upon use of wilate and may in some cases progress to severe anaphylaxis (including shock) with or without fever.
When using a factor VIII (FVIII)-containing von Willebrand Factor (VWF) product, the treating physician should be aware that continued treatment may cause excessive rise in FVIII activity. Monitor plasma levels of VWF:RCo and FVIII activities in patients receiving wilate to avoid sustained excessive VWF and FVIII activity levels, which may increase the risk of thrombotic events.
Patients with VWD, especially type 3 patients, may potentially develop neutralizing antibodies (inhibitors) to VWF, manifesting as an inadequate clinical response. Since inhibitor antibodies may occur concomitantly with anaphylactic reactions, patients experiencing an anaphylactic reaction should also be evaluated for the presence of inhibitors.
wilate is made from human plasma. As with all plasma-derived products, the risk of transmission of infectious agents, eg, viruses and, theoretically, the variant Creutzfeldt-Jakob disease (vCJD) agent or other unknown infectious agents, cannot be completely eliminated. Despite measures to reduce this risk, such products may still potentially transmit disease.
The most common adverse reactions to treatment with wilate in patients with VWD have been urticaria and dizziness. The most serious adverse reactions to treatment with wilate in patients with VWD have been hypersensitivity reactions.
