What is somatropin?
Somatropin is a form of human growth hormone. Human growth hormone is important in the
body for the growth of bones and muscles.
Somatropin is used to treat growth failure in children and adults who lack natural growth
hormone, and in those with chronic kidney failure, Noonan syndrome, Turner syndrome, short stature
at birth with no catch-up growth, and other causes. Somatropin is also used to prevent severe weight
loss in people with AIDS, or to treat short bowel syndrome.
Somatropin may also be used for other purposes not listed in this medication guide.

How should I take somatropin?
Use this medication exactly as it was prescribed for you. Do not use the medication in larger
amounts, or use it for longer than recommended by your doctor.
Your dose and brand of somatropin, and how often you give it will depend on what you are
being treated for. Follow the directions on your prescription label.
Somatropin is given as an injection under the skin or into a muscle. Your doctor, nurse, or other
healthcare provider will give you this injection. You may be given instructions on how to inject your
medicine at home. Do not use this medicine at home if you do not fully understand how to give the
injection and properly dispose of needles and syringes used in giving the medicine.
Your doctor or nurse will show you several areas on your body where you can inject
somatropin. Use a different injection place each time you give yourself the shot. Do not inject this
medicine into skin or muscle that is red, sore, infected, or injured.
Do not shake the medication vial (bottle). Vigorous shaking can ruin the medicine. When
mixing somatropin with a diluent (liquid), use a gentle swirling motion. Do not use the medication if it has
changed colors or is cloudy. Call your doctor for a new prescription.
Use each disposable needle only one time. Throw away used needles in a puncture-proof
container (ask your pharmacist where you can get one and how to dispose of it). Keep this container
out of the reach of children and pets.
To be sure this medication is helping your condition and not causing harm, your blood and
growth progress will need to be tested on a regular basis. Your eyes may also need to be checked.
Do not miss any scheduled visits to your doctor.
If you are being treated for short bowel syndrome, follow the diet plan created for you by your
doctor or nutrition counselor to help control your condition. Somatropin is not a cure for short bowel
syndrome.
If you use a form of somatropin that comes in a cartridge for use with an injection pen, use only
the pen injection system provided with the somatropin brand you use.
How you store this medicine will depend on what brand you are using and what diluent you are
mixing somatropin with. After mixing somatropin, you may need to use it right away or you may be
able to store it for later use. Read and carefully follow the instructions provided with your medicine
about proper storage of somatropin before and after it has been mixed. Ask your pharmacist if you
have any questions about proper storage of your medication.
Throw away any somatropin left over after the expiration date on the label has passed.
