Living with AT III Deficiency - Section 1
hATd has 3 distinct features that set it apart from other thrombophilias
hATd presents the highest risk of thrombosis among inherited thrombophilias18

Can be prevented and treated by replacing the missing AT1
Can be the reason why surgical patients do not have the expected response to their anticoagulation23†

IMPORTANT SAFETY INFORMATION
THROMBATE III® (antithrombin III [human]) is indicated in patients with hereditary antithrombin deficiency for treatment and prevention of thromboembolism and for prevention of perioperative and peripartum thromboembolism.
Hypersensitivity reactions may occur. Should evidence of an acute hypersensitivity reaction be observed, promptly interrupt the infusion and begin appropriate treatment.
Because THROMBATE III is made from human blood, it may carry a risk of transmitting infectious agents, eg, viruses, the variant Creutzfeldt-Jakob disease (vCJD) agent, and, theoretically, the Creutzfeldt-Jakob disease (CJD) agent. There is also the possibility that unknown infectious agents may be present in the product.
Perform coagulation tests to avoid excessive or insufficient anticoagulation and monitor for bleeding or thrombosis. Measure functional plasma AT levels with amidolytic or clotting assays; do not use immunoassays.
In clinical studies, the most common adverse reactions (≥ 5% of subjects) were dizziness, chest discomfort, nausea, dysgeusia, and pain (cramps).
The anticoagulant effect of heparin is enhanced by concurrent treatment with THROMBATE III in patients with hereditary AT deficiency. Thus, in order to avoid bleeding, the dosage of heparin (or low molecular weight heparin) may need to be reduced during treatment with THROMBATE III.
Please see full Prescribing Information for THROMBATE III.
You are encouraged to report negative side effects of prescription drugs to the FDA. Visit http://www.fda.gov/medwatch, or call 1-800-FDA-1088.
