A dose tracking method is supported by a multi-flag label construction that label-links a primary container to at least one secondary container. The dose tracking methodology comprises a series of steps including: printing information associated with a source container upon a parent label and a series of child labels, the parent and child labels forming a portion of a multi-layered, multi-flag label; adhesively attaching a transparent end of the multi-flag label to the source container, the transparent end overlying the information associated with the source container; drawing a dose from the source container into a dose container; removing a select child label from the multi-flag label; adhesively attaching the removed select child label to the dose container; and inputting the printed information from the select child label into a dose tracking mechanism.
