1. An auto-injector comprising:
a cylindrical housing configured to receive a syringe containing a medicament;
a cylindrical sleeve movably coupled to the cylindrical housing, an outer surface of the cylindrical sleeve comprising an axially-extending indicia that is viewable from an exterior of the auto-injector and comprises a green color;
a second indicia viewable from the exterior of the auto-injector, the second indicia comprising a symbol or a graphic of a second color different than the green color; and
a trigger button disposed at a proximal end of the cylindrical housing, the auto-injector being configured such that a movement of the trigger button relative to the cylindrical housing allows (i) the syringe to move distally within the cylindrical housing to insert a needle of the syringe into an injection site and (ii) a plunger to move into the syringe to drive a stopper to dispense the medicament from the syringe,
wherein the auto-injector is configured such that the axially-extending indicia and the second indicia are indicative of a first status of the auto-injector when the cylindrical sleeve and the cylindrical housing are in a first position relative to one another, and the axially-extending indicia and the second indicia are indicative of a second status of the auto-injector when the cylindrical sleeve and the cylindrical housing are in a second position relative to one another.
