Starting and staying with REBLOZYL

How can I get the most from treatment with REBLOZYL?

Your doctor prescribed REBLOZYL to treat the anemia associated with your transfusion-dependent beta (β) thalassemia (BT). This is an important part of managing your anemia associated with BT.

REBLOZYL can help manage anemia and may help reduce the number of red blood cell (RBC) transfusions you may need over time.

Before you start REBLOZYL treatment, it’s important to set treatment goals, including potential RBC transfusion reduction, with your healthcare team. Treatment goals can help you stay focused on what you want to achieve with REBLOZYL treatment. Be sure to keep talking with your healthcare team about what you want from treatment. Together, you can make sure you get the most out of REBLOZYL.

Getting the most from your treatment means working closely with your healthcare team to monitor:

  • New or changing symptoms
  • Your blood test results
  • The frequency of transfusions
  • The number of RBC units in each transfusion
  • Your REBLOZYL dose over time

It’s important that you keep track of all your transfusions and the number of RBC units in each transfusion while receiving REBLOZYL. This will help you talk with your healthcare team to get the most from REBLOZYL and meet your treatment goals. The BT Patient Brochure is a useful resource that can help you know what to expect throughout your REBLOZYL journey.
