## How should I use Omnitrope?

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.
