SC: Reconstitute each 120 mg vial with 3 mL and each 80 mg vial with 4.2 mL sterile water using 21 gauge, 2 inch reconstitution needle. Keep vial upright and swirl very gently until liquid is clear, without undissolved powder or particles. If pewder adheres to vial over the liquid surface, vial can be tilted slightly to dissolve powder. Avoid shaking to prevent foam; ring of small air bubbles on surface of liquid is acceptable. Tilt vial slightly, keeping needle in lowest part of vial and withdraw 3 mL for 120 mg dose or 4 mL for 80 mg dose. Exchange reconstitution needle for 27 gauge, 1 1/4 inch administration needle. Remove air bubbles. Grasp abdominal skin and insert needle deeply at angle not < 45°. Inject in an area free of pressure from belts, waistbands, or other types of clothing. Administer immediately after reconstitution. If administering 240 mg loading dose, repeat 120 mg injection for the second dose.
