Having hemophilia and other bleeding disorders can mean coping with various complications that can arise throughout the patient’s lifetime. For some patients, the immune system produces antibodies that “inhibit” clot formation. The presence of an inhibitor makes treating bleeds more difficult.

The National Bleeding Disorders Foundation offers several resources for families affected by inhibitors. These resources include educational events that provide meaningful community support; downloadable/printable publications and brochures; informative webinars to watch on-demand; live in-person workshops hosted by our chapter network; and referrals to websites that provide more detailed information for patients and families.


2024 Inhibitor Education

Living with an inhibitor presents unique questions and concerns for both individuals and their families. NBDF's Educational opportunities are designed to address these specific needs, offering quality education and valuable community support. Explore various avenues to enhance your understanding of inhibitors.

In-person opportunities provide an ideal setting for learning, and one such opportunity is the annual Bleeding Disorders Conference (BDC), hosted by NBDF. This year's BDC is scheduled from September 12th to 14th, 2024, in Atlanta, Georgia. Individuals with hemophilia A or B, actively dealing with an inhibitor or supporting someone who is, are encouraged to apply for the 2024 Connections for Learning Travel Grant.

Beyond inhibitor education, the conference provides multiple days of high-quality, engaging educational sessions applicable to everyone in the bleeding disorders community. Additionally, ample networking opportunities and an exhibit hall filled with resources await, helping you connect with others sharing a similar journey.

Please note, this program is offered in English and Spanish
