Abstract: A method for controlling inventory of a time sensitive medical product includes providing packaging for the medical product, setting an expiration date for the medical product; and displaying the expiration date with the medical product in a visible manner on or within the packaging or on or within the medical product. A warning period is set for warning of an upcoming expiration for the medical product in advance of the expiration date and elapsed time is monitored with the packaging or with the medical product after setting the expiration date for the medical product. A warning indicator is displayed on or within the packaging or on or within the medical product of the upcoming expiration for the medical product upon commencement of the warning period.

Abstract: A system for monitoring a time sensitive medical product includes a medical product; a packaging containing the medical product; and at least one label associated with the packaging or the medical product. The at least one label includes at least one permanent region having permanent indicia; at least one transformable region having time sensitive indicia wherein the time sensitive indicia is non-detectable in a first state and detectable in a second state; a micro-controller operatively connected to at least one of the at least one permanent region and the at least one transformable region, wherein the micro-controller monitors elapsed time and causes the at least one transformable region to change from the first state to the second state thereby revealing the time sensitive indicia in the second state; and a power source operatively connected to the micro-controller.
