The invention refers to a handheld injection device comprising a housing (10; 410) and a dose indicator (90; 480) positioned within and axially constrained to the housing (10; 410) and rotatable with respect to the housing (10; 410) during dose setting and during dose dispensing. The dose indicator (90; 480) may comprise a flexible clicker arm (95; 482) which, only during dispense, is displaced in a first radial direction and, when the device reaches its minimum dose (zero) position, in a second, opposite radial direction. |
