1. A drug delivery apparatus, comprising:

  • a drug reservoir that stores a drug therein;

    a temperature sensitive component that is at least one of the drug, the drug reservoir, or a power source that powers the drug delivery apparatus;

    a temperature sensor in thermal communication with the temperature sensitive component to sense a temperature of the temperature sensitive component;

    a transcutaneous device;

    a pump coupled to the transcutaneous device to deliver the drug via the transcutaneous device; and

    processor that;

    (i) receives from the temperature sensor an initial sensed temperature of the temperature sensitive component prior to initial delivery of the drug,(ii) calculates a time delay for the temperature sensitive component to reach, starting from the initial sensed temperature, a predetermined working temperature that is between 100 C and 37°

    C., and(iii) initiates initial delivery of the drug by the drug delivery apparatus following expiration of the calculated time delay, regardless of the temperature of the temperature sensitive component following expiration of the calculated time delay.
