• Children with closed epiphyses

• Neonates (Zorbtive)

• hypothyroidism

• diabetes mellitus.


• Reconstitute by injecting supplied diluent through rubber top of vial and aiming liquid stream at side of vial. Swirl vial gently to mix; don't shake.

• Inspect reconstituted solution. Don't use if it has visible particles or is cloudy.

Patient monitoring

• Monitor patient's height, X-rays, blood chemistry results, blood glucose level, and thyroid function studies.

Watch for signs and symptoms of leukemia.

Patient teaching

• Advise patient and parents that regular check-ups and blood tests are needed to detect adverse reactions.

• Teach parents how to reconstitute and administer drug. Stress importance of following manufacturer's instructions carefully when using prefilled cartridges.

• Teach parents about proper handling and disposal of syringes, needles, and cartridges.

• As appropriate, review all significant and life-threatening adverse reactions and interactions, especially those related to the drugs and tests mentioned above.
