Teriparatide is used to strengthen thin and weak bones in people who have or are at risk of osteoporosis. It helps stop bone loss, increase bone mass and reduce the risk of getting a fracture.
Teriparatide is to be injected subcutaneously into the fatty layer under the skin, usually in the thigh or abdomen area.
Teriparatide injection comes in a device called an injection pen.
If your doctor has asked you to inject Teriparatide on your own at home, follow his instructions carefully. Your doctor or nurse will teach you exactly how to prepare the injection and how to inject it. Remember to rotate the injection sites. Do not inject into the same area all the time. New injection sites should be at least 1.5 inches away from the previous injection site. Do not inject within a 1 inch radius of the navel (belly button).
If you need help with understanding the instructions, ask your doctor or pharmacist.
After each injection, throw away the used needle. Needles must not be re-used.
Use a brand new injection needle for each injection.
DO NOT SHAKE the injection pen. Shaking may make the medicine ineffective.
It may be necessary for you to use Teriparatide injection for a long time or even for a few years. Your doctor will advise how long you need to use this medicine.
If you miss a dose, use it as soon as you remember. If it is almost time for your next dose, skip the missed dose and return to your normal dosing schedule.
DO NOT double a dose under any circumstances.
If you often miss your scheduled injection, let your doctor and pharmacist know.

- overactive parathyroid gland
- a condition called “Paget's disease”(a painful bone condition which can cause abnormal bone growth and deformity)

Teriparatide may cause any of the following side effects: difficulty sleeping, rash, nausea, stomach pain, indigestion and joint pain.
You may feel dizzy when getting up from a sitting or lying down position, especially if you are using Teriparatide for the first time. This is common and should disappear gradually as you get used to the medicine. It will help if you get up slowly from a sitting or lying down position.
