Making a plan

You can get a bleed while taking HEMLIBRA®. You and your healthcare provider will discuss a plan on when and how to treat and/or manage a bleed. It is important that you stick with the dosing and treatment plan you discussed with your healthcare provider.

Use of bypassing agents

HEMLIBRA increases the potential for your blood to clot. Discontinue prophylactic use of bypassing agents the day before starting HEMLIBRA prophylaxis. Carefully follow your healthcare provider’s instructions regarding when to use an on-demand bypassing agent, and the dose and schedule you should use. HEMLIBRA may cause serious side effects when used with aPCC (FEIBA®), including thrombotic microangiopathy (TMA) and blood clots (thrombotic events).
