A drug temperature control device (1), used for controlling the temperature of a drug (3) stored in an injection pen (2), comprises a housing (10), a temperature sensor (11), a temperature control element (12), a heat dissipation element (13), a cold conduction element (14), and a control circuit board (15). The housing (10) is provided with an accommodation chamber (10a) capable of accommodating part of the injection pen (2), and is provided with at least one air hole (10b). The temperature sensor (11) is disposed in the accommodation chamber (10a) and is adjacent to the injection pen (2), and is used for measuring the temperature of the drug (3). The temperature control element (12) is disposed in the accommodation chamber (10a), and is provided with a refrigeration end (12a) and a heat dissipation end (12b). The heat dissipation element (13) is disposed at the heat dissipation end (12b) of the temperature control element (12), and is close to the air hole (10b). The cold conduction element (14) is disposed at the refrigeration end (12a) of the temperature control element (12), and is used for surrounding part of the injection pen (2). The control circuit board (15) is electrically connected to the temperature sensor (11) and the temperature control element (12), and is used for driving the temperature control element (12) according to a temperature value measured by the temperature sensor (11).Linvention concerne un dispositif de régulation de température de médicament (1), utilisé pour réguler la température dun médicament (3) stocké dans un stylo dinjection (2), lequel dispositif de régulation de température de médicament comprend un boîtier (10), un capteur de température (11), un élément de régulation de température (12), un élément de dissipation de chaleur (13), un élément de conduction de froid (14), et une carte de circuits imprimés de commande (15).
