A syringe for delivering medication through an intravenous port, or for providing a combination of medications includes a barrel with a plunger in slidable and sealing engagement therein, and a piercing member formed integrally with the barrel. The piercing member includes a bore in communication with the distal end of the barrel, and a piercing point and an aperture at a distal end of the piercing member. The distal end of the barrel sealingly connects to a transport cap, an intravenous port or an injection needle. The distal end of the piercing member is removable and includes an external recess and a corresponding internal step to define a separation plane for the distal end of the piercing member. The piercing member is used to draw up one or more medications into the barrel, and is then removed to enable the transport cap to be attached to seal the contents.
