The physician information should contain the following key elements: • Clear demarcation of the new formulation of NovoSeven from original NovoSeven, with clear descriptions of any differences in the vial sizes, colour codes and dosing and reconstitution instructions • Clear information about their difference in concentration. • Information about the potential safety risks of errors in dosing calculation resulting from the confusion between the two formulations and its possible clinical consequences (e. g. potential for thrombotic risk if overdose). • Encouragement to report medications errors and their causes and consequences.
