A syringe injection aid apparatus comprises a body having a lower opening defined by an actuation collar, a syringe-interfacing plunger substantially slidably contained within the body, and a locking mechanism pivotally secured to the body. The locking mechanism is configured to prevent forward movement of the syringe-interfacing plunger when in a locked position and to enable forward movement of the syringe-interfacing plunger when in an unlocked position. The unlocked position is activated by external contact with the actuation collar.
