Anticoagulants for Antithrombin Deficiency: What You Need to Know
Published: May 06, 2024
Anticoagulants are a lifeline for those with antithrombin deficiency. Learn about the options and how they work to keep you safe.
Warfarin: The Traditional Choice
Warfarin has long been used to treat individuals with antithrombin deficiency. It works by inhibiting vitamin K, which is crucial for making clotting factors in the liver. Regular blood tests, known as INR tests, are needed to ensure the dose is correct, making sure the blood is not too thin or too thick.
Direct Oral Anticoagulants (DOACs)
DOACs are a newer option with the advantage of not requiring regular blood tests like warfarin. These medications, such as apixaban and rivaroxaban, directly inhibit specific clotting factors, reducing the risk of clots. They are often preferred for their ease of use but may not be suitable for everyone.
When to Use Antithrombin Concentrates
In certain situations, such as surgery or when anticoagulants can't be used, antithrombin concentrates may be administered. These products, derived from human plasma or produced recombinantly, help replenish low antithrombin levels quickly. Consultation with a healthcare provider is necessary to determine if this treatment is appropriate.
