For diabetic patients:
The dose of anti-hyperglycemic medications may need to be adjusted regularly.
Patients with growth hormone deficiency secondary to an intracranial neoplasia or lesion:
should be examined frequently for progression or recurrence of the underlying lesion, so as to ensure inactive lesions before the initiation of therapy with (rhGH).
Dose selection for elderly patients, impaired hepatic and renal function patients.
Patients with premature epiphyseal closure. (Epiphysis disorders).
Patients with history of scoliosis and malignant diseases.
Patients with growth failure secondary to chronic renal insufficiency
Patients with Turners syndrome:
should be evaluated for Otitis media and other Relative deficiencies of other pituitary hormones.
Untreated hypothyroidism:
Hypothyroidism may interfere with the response to Somatropin 4.0 I.U injection a state of hypothyroidism may develop during treatment with Somatropin 4.0 I.U, so patients should have periodic thyroid gland tests and treated with thyroid hormone when indicated.
Patients with co-existing ACTH deficiency:
Adjustment of gluco-corticoid therapy to avoid the inhibitory effect on growth.

Dosage and administration:
The dose should be individualized, expressed in units 1 mg Somatropin= 3.0 I.U.

For subcutaneous injections:

  • 0.1- 0.2 I.U/kg body weight, 6-7 times a week, or 2-3 I.U/m2 body surface area 3 times a week.
  • 0.2- 0.24 I.U/kg body weight, 3 times a week
  • or 4-6 I.U/m2 body surface area 3 times a week.

For other applications please consult your medical expert.

Duration of administration:
Therapy should be initiated before the onset of puberty & children should be treated before epiphyseal closure or the patient has not reached the satisfactory adult height.

Adverse reactions:
Discomfort at the site of injection &/ or mild transient edema have been sometimes reported in early stages following administration, but occurrence rates decreases as the therapy continues. Musculoskeletal arthralgia.
Gynecomastia.

Drug interaction:
Patients with co-existing ACTH deficiency should have their glucocorticoid replacement dose carefully adjusted to avoid an inhibitory effect on growth.

Side effects:
