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. A clock and a keypad for inputting data relating to an expiration date for the medical product are operatively connected to the micro-controller respectively.
