Omnitrope is a form of human growth hormone important for the growth of bones and muscles.

Omnitrope is used to treat growth failure in children and adults who lack natural growth hormone. This includes people with with Turner syndrome, Prader-Willi syndrome, short stature at birth with no catch-up growth, and other causes.

Omnitrope may also be used for purposes not listed in this medication guide.

You should not use Omnitrope if you have cancer, eye problems caused by diabetes, or if you are being treated for Prader-Willi syndrome and you are overweight or have severe breathing problems. You should not use Omnitrope if you have a serious illness due to lung failure or complications from recent surgery, injury, or medical trauma.

Before you receive Omnitrope, tell your doctor about all your past and present medical conditions, especially allergies, trauma, surgery, diabetes, cancer, breathing problems, liver or kidney disease, scoliosis, high blood pressure, pancreas disorder, underactive thyroid, or a brain tumor.

Also tell your doctor about all other medications you use, especially steroids or diabetes medications. Your dosages of these medicines may need to be changed when you start using Omnitrope. Do not stop using a steroid suddenly or change any of your medication doses without your doctor's advice.

Call your doctor at once if you have sudden and severe pain in your upper stomach with nausea and vomiting, fast heartbeat, increased thirst or urination, weight loss, or vision changes and sudden, severe pain behind your eyes.

Use Omnitrope exactly as prescribed by your doctor. Your dose will depend on what you are being treated for. Follow all directions on your prescription label. Do not use this medicine in larger or smaller amounts or for longer than recommended.

Omnitrope is injected into a muscle or under the skin. You may be shown how to use injections at home. Do not self-inject this medicine if you do not understand how to give the injection and properly dispose of used needles and syringes.

Your care provider will show you the best places on your body to inject Omnitrope. Use a different place each time you give an injection. Do not inject Omnitrope into the same place two times in a row.

Prepare your injection only when you are ready to give it. Do not shake the medicine. Do not use if the medicine has changed colors or has particles in it. Call your pharmacist for new medicine.

Use a disposable needle and syringe only once. Follow any state or local laws about throwing away used needles and syringes. Use a puncture-proof "sharps" disposal container (ask your pharmacist where to get one and how to throw it away). Keep this container out of the reach of children and pets.

While using Omnitrope, you may need frequent blood tests. Your growth progress will need to be tested often. Your eyes may also need to be checked.

If you have Prader-Willi syndrome, your treatment program may also include weight control. Follow your doctor's instructions very closely.

Throw away any Omnitrope left over after the expiration date on the label has passed.

You should not use Omnitrope if you are allergic to somatropin or benzyl alcohol, or if you have:

• a serious illness due to lung failure or complications from recent surgery, injury, or medical trauma;

• closed epiphyses;

• active cancer;

• eye problems caused by diabetes (diabetic retinopathy); or

• if you are being treated for Prader-Willi syndrome and you are overweight or have severe breathing problems (including sleep apnea).
