An improved syringe (10) that allows one-handed operation, without requiring the user to reposition her hands during any portion of the injection process. The syringe (10) comprises a housing (20) having a plunger (30) disposed therein that expels medication through a needle (50) when the plunger (30) is pressed toward the opposing end wall (22). Instead of having the needle (50) in the same axis as the plunger (30) the needle port (26) is carried by the wall of the syringe housing (20) at an acute angle with respect to the longitudinal axis of the housing (20). With this configuration, the housing (20) can be gripped between a finger and thumb, with one of the fingers on the handle (40) and the other finger on the end wall (22) of the housing (20). A pair of rings (42) positioned at opposing ends of the housing (20) receive the user's fingers which create both suction as well as pressure for injection of medication from the housing's chamber (21).
