Blood Transfusions

Learning about blood transfusion reactions

Transfusion reactions are rare. If they do happen, they most often happen during your blood or blood product transfusion or within 6 hours of your transfusion. In some rare cases, a transfusion reaction can happen 2 to 3 weeks after a transfusion.

Watch for symptoms that might be showing a transfusion reaction. If you begin to feel unwell, like having a fever, chills, muscle pain, or trouble breathing, you may be having a transfusion reaction.

You can have a transfusion reaction even if you have had transfusions in the past without a reaction.

If you had any of these symptoms after your transfusion, tell your healthcare provider about it the next time you have a transfusion.

Follow your doctor’s instructions for any more blood tests or transfusions you may need. Be sure to make and go to all appointments, and call your doctor or Health Link at 811 if you are having problems. If your doctor did not give you any follow-up instructions, call them 1 to 3 days after your transfusion to see if you need more tests.
