A syringe is provided for limiting the dosage of medication delivered to a patient to a pre-determined amount. The syringe assembly includes an injector assembly and vial of medication. The injector assembly has an adjustable dosage control which rides in a track on the injector assembly for limiting vial movement. Once an appropriate dosage is selected using the dosage control, the vial is engaged with the injector assembly. As the vial is pressured into the injector assembly medication is forced through the needle. Once the vial reaches the dosage control, vial movement is obstructed and dosage effectively limited.
