What is the Most Important Information I Should Know About Forteo
In rats that were treated with Forteo for more than a quarter of their lifetime, teriparatide caused some rats to develop osteosarcoma, a bone cancer. The potential to cause osteosarcoma in rats was increased with higher doses and longer periods of treatment.
Osteosarcoma in humans is a serious but very rare cancer. Osteosarcoma occurs in about 4 out of every million people each year.
There is one report of osteosarcoma in a patient administered Forteo for 14 months. Due to the complex medical history, cause and effect between Forteo and osteosarcoma could not be established. At present, it is not known whether humans treated with Forteo would have an increased chance of getting osteosarcoma.
You should discuss any safety concerns you have about the use of Forteo with your doctor.
What Forteo is Used For
Forteo is used to treat osteoporosis in women after menopause and in men.
Osteoporosis is a disease which causes bones to become less dense, gradually making them weaker, more brittle and likely to break. This disease is especially common in women after the menopause. Osteoporosis is also common in patients receiving corticosteroids such as prednisone, cortisone.
Although it may have no symptoms at first, osteoporosis makes you more likely to break bones, especially in your spine, hips and wrists and may cause back pain, loss of height and a curved back.
This medicine is a recombinant parathyroid hormone.
It works by activating cells in the bone to form new bone. Using this medicine each day will protect your bones by making them stronger and your risk of fracture will be reduced.
Ask your doctor if you have any questions about why this medicine has been prescribed for you.
Your doctor may have prescribed it for another reason.
This medicine is available only with a doctor's prescription.
This medicine is not expected to affect your ability to drive a car or use machinery.

After Using Forteo
Keep your Forteo pen in the refrigerator where the temperature stays between 2° to 8°C. Do not allow Forteo to freeze. Do not use Forteo if it has been frozen.
Keep it where children cannot reach it.
You should have your Forteo injection shortly after you take the pen out of the refrigerator as described in the user manual. Put the pen back into the refrigerator immediately after you have used it.
You should use a new needle for each injection. Do not store your pen with the needle attached. If you do this, it may allow solution to leak from the pen and air bubbles to form in the cartridge.
Each Forteo pen can be used for up to 28 days after the first injection. After the 28-day use period, discard the pen even if it contains some unused solution.
Forteo is a clear and colourless liquid. Do not use if solid particles appear or if the solution is cloudy or coloured.
