A locking assembly for a medication dispensing device including a housing, a drive member, a medication cartridge having a barrel holding medication between a movable plunger and a septum, and a dose delivery mechanism for controlling the advancement of the drive member. The locking assembly, in one form, includes a lock member, biased to move from a first position to a second position, with a first actuating element. The locking assembly also includes a second actuating element disposed on the drive member and cooperatively configured with the first actuating element. If the drive member of the device moves rearward from the shipped position due to a freezing of the medication, the second actuating element engages the first actuating element such that the lock member moves from the first position to the second position to lock the medication dispensing device from further dose dispensing.
