Circular of Information
The Circular of Information for the Use of Human Blood and Blood Components (“the Circular”) serves as an extension of the product label, providing indications for the use of blood and blood components, precautions, instructions for administration, and adverse effects of transfusion. It is recognized by the Food and Drug Administration as an acceptable extension of container labels. Like a package insert for prescription drugs, it is an important part of the labeling of a blood component. The Code of Federal Regulations, Title 21, requires it to be available for distribution with blood and blood components intended for transfusion.
