Needle Selection - Overview

Consistent with the INVEGA TRINZA® Prescribing Information:

• Deltoid Injection - The recommended needle size for administration of INVEGA TRINZA® into the deltoid muscle is determined by the patient’s weight:
  • For patients weighing less than 90 kg, the 1-inch, 22 gauge thin wall needle is recommended.
  • For patients weighing 90 kg or more, the 1½-inch, 22 gauge thin wall needle is recommended.

• Administer into the center of the deltoid muscle. Deltoid injections should be alternated between the two deltoid muscles.
• Gluteal Injection - Regardless of patient weight, the recommended needle size for administration of INVEGA TRINZA® into the gluteal muscle is the 1½-inch, 22 gauge thin wall needle. Administer into the upper-outer quadrant of the gluteal muscle. Gluteal injections should be alternated between the two gluteal muscles.
