What is Hemlibra?
Hemlibra is a prescription medicine used for routine prophylaxis to prevent or reduce the frequency of bleeding episodes in adults and children with hemophilia A with factor VIII inhibitors.
- Hemophilia A is a bleeding condition people can be born with where a missing or faulty blood clotting factor (factor VIII) prevents blood from clotting normally.
- Hemlibra is a therapeutic antibody that bridges clotting factors to help your blood clot.
