What is Forteo?
Forteo is for use when you have a high risk of bone fracture due to osteoporosis.
Forteo has caused bone cancer (osteosarcoma) in animals but it is not known whether this would occur in people using this medicine. Talk with your doctor about your own risk.
Tell your doctor if you have conditions such as Paget's disease, high blood levels of calcium or alkaline phosphatase, or a history of bone cancer or radiation treatment involving your bones.
Avoid smoking cigarettes or drinking alcohol. Smoking or heavy drinking can reduce your bone mineral density, making fractures more likely.

How should I use Forteo?
Use Forteo exactly as prescribed by your doctor. Follow all directions on your prescription label and read all medication guides or instruction sheets.
Forteo is injected under the skin. A healthcare provider may teach you how to properly use the medication by yourself.
Forteo is usually given once per day at the same time each day.
Read and carefully follow any Instructions for Use provided with your medicine. Ask your doctor or pharmacist if you don't understand all instructions.
Prepare the Forteo injection only when you are ready to give it. Do not use if the medicine looks cloudy, has changed colors, or has particles in it. Call your pharmacist for new medicine.
Your healthcare provider will show you where on your body to inject Forteo. Use a different place each time you give an injection. Do not inject into the same place two times in a row.
Use only the injection pen provided with Forteo. Do not transfer the medicine to a syringe or other injection device or you could get an overdose.
Teriparatide can cause you to feel dizzy or light-headed. Always give your injection at a time and place where you can sit or lie down for a short time afterward.
Each prefilled injection pen contains enough teriparatide for 28 separate injections. Throw the pen away after 28 injections, even if there is still medicine left inside.
Forteo may be only part of a complete treatment program that also includes diet, exercise, taking vitamin or mineral supplements, and changing certain behaviors. Follow your doctor's instructions very closely.
Store the Forteo injection pen in a refrigerator when not in use. Take the pen out of the refrigerator only long enough to use it. After use, remove the needle, recap the pen, and return it to the refrigerator.
Use a needle and syringe only once and then place them in a puncture-proof "sharps" container. Follow state or local laws about how to dispose of this container. Keep it out of the reach of children and pets.
Do not freeze Forteo, and throw away the medicine if it has become frozen.
Your doctor will determine how long to treat you with this medicine. Forteo is sometimes given for only 2 years.
