  • What is Omnitrope?

    Omnitrope is used to treat children who are not growing because they are not producing enough growth hormone, have Prader-Willi Syndrome (PWS), were born small for gestational age (SGA), or have idiopathic short stature (ISS). This drug is also used in adults to treat growth hormone deficiency (GHD).

  • What is the most important information I should know about Omnitrope?

    Whether your doctor prescribes Omnitrope for injection or Omnitrope cartridge for use in a pen delivery system, you must read the instructions on the leaflet provided with your prescription. If you have additional questions or concerns, contact your doctor.

    Your blood sugar levels will be monitored regularly, especially if you are at risk for diabetes such as having obesity, Turner Syndrome, or a family history of diabetes. The doses of your diabetes medications may have to be adjusted.

    You may experience an increase in the pressure within the skull. Symptoms include papilledema (swelling of the optic nerve), changes in your vision, headache, nausea, and vomiting. Your doctor will regularly check your eyes for papilledema. If it is present, Omnitrope should be stopped.

    Fluid accumulation may occur with Omnitrope treatment in adults.

    If you have low thyroid hormone levels or an underactive thyroid gland that is not treated, you may not respond to Omnitrope as well. Your doctor will check your thyroid function and, if necessary, start or change your thyroid hormone replacement therapy.

    If children develop a limp or hip or knee pain, immediately tell the doctor.

    If you were previously treated with somatropin (the active ingredient in Omnitrope) replacement therapy as a child, your doctor will reevaluate you before continuing therapy at the reduced dose level recommended for GHD in adults.
