Humatrope® (somatropin for injection) is used to treat:
Children who do not make enough growth hormone on their own, have short stature associated with Turner syndrome, or have SHOX deficiency; have idiopathic short stature, which means they are shorter than 98.8% of other children of the same age and sex, are growing at a rate not likely to allow them to reach normal adult height, and for whom no other cause of short stature can be found; were born smaller than normal for the number of weeks of pregnancy and who do not catch up in height by 2 to 4 years of age.
Adults who have growth hormone deficiency that began either in adulthood (as a result of pituitary disease, hypothalamic disease, surgery, radiation therapy, or trauma) or in childhood. Patients treated for growth hormone deficiency in childhood whose bones have stopped growing should be reevaluated to determine if they should continue growth hormone.
IMPORTANT SAFETY INFORMATION FOR HUMATROPE
What is the most important information I should know about Humatrope?
Do not take Humatrope if you are having serious complications after having open heart surgery, abdominal surgery, or serious injuries involving many body systems, or are having life-threatening breathing problems. Deaths have been reported in such cases.
Do not use Humatrope in children with Prader-Willi syndrome who are severely obese or have a history of blocked upper airways or other severe breathing problems, or sleep apnea. Deaths have been reported in such cases. Humatrope is not approved for the treatment of patients with Prader-Willi syndrome.
Do not use Humatrope if you have active cancer. Growth hormone deficiency can be an early sign of some tumors in the brain or pituitary gland. The presence of these types of tumors should be ruled out by your doctor before you start Humatrope.
Serious allergic reactions have been reported with Humatrope. Humatrope is contraindicated if you know you have allergies to growth hormone or any of its ingredients. Tell your doctor if you have an allergic reaction. Do not mix Humatrope with the supplied diluent if you are allergic to metacresol or glycerin.
Your doctor should check your blood sugar regularly while you are taking Humatrope, especially if you have diabetes, pre-diabetes, or risk factors for diabetes. New cases of type 2 diabetes have been reported in patients taking Humatrope.
Tell your doctor if you have any visual changes accompanied by headache, nausea, and/or vomiting while taking Humatrope. This may be a sign of increased pressure in the brain.
Adults may retain water during Humatrope treatment. This may be brief and may increase with higher doses of Humatrope.
If you have hypoadrenalism and are on glucocorticoid replacement therapy, your doctor may increase your dosage when you initiate growth hormone treatment.
Your doctor should test your thyroid function periodically during Humatrope therapy. Thyroid hormone treatment may need to be started or adjusted.
Fracture in the ball of the hip joint can occur in children who have endocrine problems and in children who have rapid growth. Any child taking Humatrope who develops a limp or complains of hip or knee pain should be seen by a doctor to check for this.
Progression of curvature of the spine (scoliosis) can occur in children who have rapid growth. Humatrope has not been shown to increase the occurrence of this condition. If the child has scoliosis, the doctor should carefully monitor the progression of the scoliosis during Humatrope treatment.
Cases of pancreatitis (inflammation of the pancreas) have been reported rarely in children and adults receiving growth hormone. Consult a doctor if you develop abdominal pain while taking Humatrope.
You should rotate your injection sites to avoid breakdown of skin and fat. Seek prompt medical attention for any allergic reaction you experience to the injection of Humatrope.
