How should I use somatropin?
Use exactly as prescribed by your doctor. Do not use in larger or smaller amounts or for longer than recommended. Follow the directions on your prescription label.
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 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 fully understand how to give the injection and properly dispose of used needles and syringes.
Use a different place on your body each time you give the injection. Your care provider will show you the best places on your body to inject the medication. Do not inject into the same place two times in a row. Do not inject this medicine into skin or muscle that is red, sore, infected, or injured.
Do not shake the medication bottle or you may 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 has particles in it. Call your doctor for a new prescription.
Use a disposable needle only once. 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 often. Your eyes may also need to be checked. Visit your doctor regularly.
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.
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 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.
What other drugs will affect somatropin?
Before using somatropin, tell your doctor if you use insulin or take oral (by mouth) medicine to treat diabetes. Somatropin may affect blood sugar levels and you may need to adjust your dose of the diabetes medication. Do not change the dose of your diabetes medication without your doctor's advice.
Tell your doctor if you use any type of steroid medicine such as cortisone, dexamethasone, methylprednisolone, prednisone, and others. Steroids can make somatropin less effective and your doses may need to be adjusted. Do not stop using a steroid suddenly. Follow your doctor's instructions.
Tell your doctor about all other medications you use, especially cyclosporine (Gengraf, Neoral, Sandimmune), seizure medication, birth control pills, anabolic steroids, or hormone replacement medications for men or women.
This list is not complete and other drugs may interact with somatropin. Tell your doctor about all medications you use. This includes prescription, over-the-counter, vitamin, and herbal products. Do not start a new medication without telling your doctor.
