Important safety information:

  • Do NOT use more than the recommended dose or change your dose without checking with your doctor.
  • Severe and sometimes fatal lung and breathing problems have occurred with the use of somatropin in certain children with Prader-Willi syndrome. These children were usually either very overweight or had severe breathing problems (eg, airway blockage, sleep apnea, lung or airway infection). The risk may be greater in boys. Children with Prader-Willi syndrome should have certain breathing tests before they start Saizen. 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, increased pressure in the head has been reported in patients using somatropin. The risk may be greater in patients with chronic kidney problems, Turner syndrome, or Prader-Willi syndrome. Symptoms usually occurred within the first 8 weeks after the start of treatment. The symptoms have gone away after the dose was lowered or treatment was stopped. Discuss any questions or concerns with your doctor. Contact your doctor right away if you develop symptoms such as vision changes or severe headache, nausea, or vomiting.
  • Pancreas inflammation (pancreatitis) has been reported rarely in patients who use Saizen. The risk may be greater in children, especially in girls who have Turner syndrome. Contact your doctor right away if you develop severe stomach or back pain.
  • Rarely, children using Saizen 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.
  • Saizen may raise your blood sugar. High blood sugar may make you feel confused, drowsy, or thirsty. It can also make you flush, breathe faster, urinate more often, or have a fruit-like breath odor. If these symptoms occur, tell your doctor right away.
