When should I call my doctor after a blood transfusion?

Reactions to a blood transfusion can happen at unexpected times. You can have a reaction during the transfusion, a day afterward or up to several months later. Call your healthcare provider right away (or your nurse if you are still in the hospital) if you experience:

  • Bleeding, pain or new bruising at the IV site.
  • Cold and clammy skin, fever or chills.
  • Dark or reddish urine.
  • Fast heartbeat, chest pain, trouble breathing or wheezing.
  • Headache, dizziness, nausea or vomiting.
  • Rash, hives or itching.
  • Severe back pain.
