Discard the syringe in a biohazard sharps container.C.Retractable needle (Vanish Point Syringe)1.Administer the injection following the proper technique.2.After administering the medication, continue depressing the plunger with the thumb. Use firm pressure past the point of initial resistance. This action delivers the full dose of medication to the patient and activates the needle retraction device, causing the needle to retract automatically from the patient’s skin and into the barrel of the syringe.3.Discard the syringe in a biohazard sharps container.
