I will have a blood transfusion for anemia. How long do you stay in the hospital after a blood transfusion for anemia?
30 minutes.
Medical staff usually likes to monitor their patients for at least half an hour after a transfusion for reactions, typically longer. The duration of your hospital stay will likely more largely be determined by whether or not a cause to your anemia has been identified and appropriately addressed.
You may return home fifteen minutes after the transfusion.
