An apparatus includes a syringe body and a plunger. The syringe body defines a volume configured to contain a medicament. A proximal end portion of the syringe body includes an engagement portion, and a distal end portion of the syringe body includes a delivery tip. A side wall of the syringe body includes a transparent window. The plunger has a distal end portion configured to move within the volume of the syringe body to convey the medicament. An engagement portion of the plunger is configured to interface with the engagement portion of the syringe body to limit rotation of the plunger about a longitudinal axis of the plunger. An outer surface of the plunger includes a series of indicia, at least one which is visible through the transparent window.
