An injector for delivering liquid can include a body having a proximal end, a distal end, a longitudinal axis, and a track follower adjacent to the proximal end. A plunger can be disposed at least partially within the body and movable with respect to the body along the longitudinal axis. An actuator can be positioned at the proximal end of the body and operably connected to the plunger. The actuator can include a track having a first portion and a second portion. The first portion can limit travel of the actuator along the longitudinal axis to deliver a first predetermined amount of the liquid. The second portion can limit travel of the actuator along the longitudinal axis to deliver a second predetermined amount of the liquid. The actuator can be positionable to selectively control displacement of the plunger pursuant to the first portion or the second portion of the track.

A medication injector that has an alert indicator that alerts the user when the medication injector is approaching near the end of its medication supply is disclosed. The alert indicator gives the user an opportunity to make preparations to obtain additional medication for the injector if there is an insufficient amount of medication in the injector to enable the user to dispense the required dosage amount with the next injection. Initially, the alert indicator is not visible to the user, but becomes visible to the user when the injector is near empty.
