Generic Name: somatropin (rdna origin - refrigerated) (SOE-ma-TROE-pin)
Brand Name: Genotropin

Genotropin is used for:

Treating certain children or adults whose bodies do not produce enough growth hormone. It is also used to treat certain children who are not growing normally due to Turner syndrome or Prader-Willi syndrome, or who were born small for gestational age (SGA). It may also be used for other conditions as determined by your doctor.

  • you have active or recurring cancer, a brain tumor, or other unusual growths
  • you have severe breathing problems (eg, respiratory failure) or serious illness caused by complications from surgery or injury
  • you have a certain type of eye problem caused by diabetes (diabetic retinopathy)
  • the patient is a child who has Prader-Willi syndrome and is severely overweight or has severe breathing problems (eg, airway blockage, respiratory infection, sleep apnea)
  • the patient is a child who has epiphyseal closure (bone growth is complete)

Contact your doctor or health care provider right away if any of these apply to you.

Children with Prader-Willi syndrome should have certain breathing tests before they start Genotropin. They should be monitored for signs of lung or airway infection. They should also have effective weight control. Contact the doctor at once if the patient develops irregular breathing during sleep, new or increased snoring, or symptoms of lung or airway infection (eg, fever, coughing, sore throat, shortness of breath, chest pain or discomfort).
  • Rarely, children using Genotropin have experienced a slipped growth plate in the hip. Contact the doctor right away if the patient develops hip or knee pain or a limp.
  • Pancreas inflammation (pancreatitis) has been reported rarely in patients who take Genotropin. The risk may be greater in children, especially in girls who have Turner syndrome. Contact your doctor right away if you develop stomach or back pain.
  • Diabetes patients - Genotropin may affect your blood sugar. Check blood sugar levels closely. Ask your doctor before you change the dose of your diabetes medicine.
