Immediately before the injection, the syringe must be shaken, the protective cap removed from the needle and the air removed from the syringe by holding it upright with the needle and slowly pressing the piston.When a dose of 0.25 ml is introduced, the movement of the syringe piston is stopped at a time when its inner surface reaches the lower edge of the needle retainer.
