About Us

On behalf of Novo Nordisk’s BioPharm Medical, we would like to welcome you to our Hemophilia & Rare Bleeding Disorders website. We invite you to explore the website and encourage you to visit the site for updates and news items. The main goal for the Medical Affairs team at Novo Nordisk, Inc. is to improve patients' lives by being medical leaders through developing and communicating medical knowledge and providing expertise regarding our products and disease states. 

Beyond developing innovative products, Novo Nordisk, Inc. aspires to meet the broad goal of Changing Possibilities in Hemophilia. For the medical team, this means engaging with the community to better understand the challenges of living with or caring for somebody with a bleeding disorder, where current approaches have been successful in driving better outcomes, and where unmet needs remain.

We started RareBleedingDisorders.com to connect patients, caregivers, families, and others in their community with reliable, easy-to-understand, and practical information that can help you better understand your disease. In this effort, we were fortunate to have patients, caregivers, and healthcare professionals contribute to development of this content and commit to keeping the content fresh.

Feel free to contact us any time.

If you have questions we haven’t answered here, please feel free to reach out—we’d love to hear from you!
