Accretropin™ (somatropin) is indicated for:

• treatment of pediatric patients who have growth failure due to an inadequate secretion of normal endogenous growth hormone.
• treatment of short stature associated with Turner Syndrome in pediatric patients whose epiphyses are not closed.

The dose regimen for Accretropin™ [(somatropin) for injection] should be individualized for each patient. Therapy should not be continued if epiphyseal fusion has occurred. Response to growth hormone therapy tends to decrease with time. However, failure to increase growth rate, particularly during the first year of therapy, should prompt close assessment of compliance and evaluation of other causes of growth failure such as hypothyroidism, under-nutrition and advanced bone age.

Growth hormone deficiency – The recommended weekly dose is 0.18 mg/kg body weight to 0.3 mg/kg (0.90 IU/kg) body weight. The dose should be divided into equal daily doses given 6 or 7 times per week subcutaneously.

Turner Syndrome – The recommended weekly dose is 0.36 mg/kg of body weight. The dose should be divided into equal daily doses given 6 or 7 times per week subcutaneously.

Accretropin™ should not be injected intravenously.

Administration – the vial should be swirled with a GENTLE rotary motion. DO NOT SHAKE. The solution should be inspected for clarity. It should be clear. If the solution is cloudy or contains particles, the contents MUST NOT be injected.

Storage

Vials of Accretropin™ Injection should be stored in the refrigerator [2° to 8°C (36° to 46°F)]. Avoid freezing and shaking. Expiration dates are stated on the vial and carton labels.
