Abstract

A drug delivery device for selecting and dispensing a number of user variable doses of a medicament includes a dose limiter for preventing the setting of a dose, which exceeds the amount of liquid left in a cartridge of the drug delivery device. The device includes a cartridge containing liquid, a dosing element, which rotates during dose selecting, a last dose nut coupled to the dosing element during dose selecting such that rotation of the dosing element causes an axial movement of the last dose nut, and a stop element, which is provided on the dosing element and which blocks further movement of the last dose nut, if a dose is selected corresponding to the amount of liquid left in the cartridge. The device further includes a last dose sleeve rotationally coupled to the dosing element during dose selecting and rotationally decoupled from the dosing element during dose dispensing.
