Why is medication not allowed to be infused into the blood transfusion set while a blood transfusion is going on?

Every blood transfusion carries the risk of allergic reaction, to anaphylactic shock, even if blood type is perfectly matched. If medication was also infused along with the blood, and the patient had an allergic reaction, it would be impossible to tell which sustance was causing the reaction: the blood? or the medication? Remember that every transfusion reaction can be deadly. As well, some meds may break down blood components. Therefore, never inject IV meds into a transfusion tubing or combine medications into a blood transfusion set.
