What is Forteo?
Forteo, a synthetic form of paraathyroid hormone, is found naturally in the human body. Teriparatide can increase bone mineral density and bone strength and prevent fractures. Forteo treats osteoporosis that is caused by menopause or gonadal failure. Forteo should be used when there is a high risk of fractures due to osteoporosis.
Warnings
Forteo causes bone cancer (osteosarcoma) in animals, but it is unknown if this will occur in humans who use this medicine. Speak to your physician about the risks you are exposed to. If you have a history of bone cancer, radiation therapy, or high levels of alkaline or calcium phosphatase in your blood, tell your doctor. Do not smoke or drink alcohol. Heavy drinking or smoking can cause your bone density to decrease, increasing the risk of fractures.

Give your injection at a place and time where you will be able to sit or lay down for a few minutes afterward. Each prefilled pen contains enough teriparatide to perform 28 injections. After 28 injections, throw away the pen, even if it still contains medicine. Forteo is only one part of an overall treatment plan that may include diet, exercise, and taking vitamin or mineral supplements. You should follow your doctor's advice.
When not in use, store the Forteo Injection Pen in the refrigerator. Only remove the pen from the fridge for the time it takes to use the product. Remove the needle and cap the pen after use. Then, return it to your refrigerator. Only use a needle or syringe once, and then store them in a "sharps container" that is puncture-proof. Be sure to follow local or state laws on how to properly dispose of the container. Keep the container out of the reach of pets and children. Forteo should not be frozen. If it is, throw the medicine away. The length of treatment with Forteo will be determined by your doctor. Forteo can be prescribed for as little as two years.
