How should I use Genotropin (somatropin)?
Your dose and brand of somatropin, and how often you give it 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.
Somatropin 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 somatropin. Use a different place each time you give an injection. Do not inject into the same place two times in a row.
Do not shake the medication bottle or you may ruin the medicine. Prepare your dose only when you are ready to give an injection. 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 somatropin, 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 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 have Prader-Willi syndrome, your treatment program may also include weight control. Follow your doctor's instructions very closely.
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.
What happens if I miss a dose?
Use the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not use extra medicine to make up the missed dose.
Call your doctor if you miss more than 3 doses in a row.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.
Overdose can cause tremors or shaking, cold sweats, increased hunger, headache, drowsiness, weakness, dizziness, fast heartbeat, and nausea. Long-term overdose may cause excessive growth.
What should I avoid while using Genotropin (somatropin)?
If you use Zorbtive to treat short bowel syndrome, avoid drinking fruit juices or soda beverages. Follow the instructions of your doctor or nutrition counselor about what types of liquids you should drink while using Zorbtive.
Avoid drinking alcohol if you have short bowel syndrome. Alcohol can irritate your stomach and could make your condition worse.
