Why is this medicine prescribed?
Abaloparatide injection is used to treat osteoporosis (condition in which the bones become thin and weak and break easily) in women who have undergone menopause ('change in life,' end of menstrual periods), who are at high risk of fractures (broken bones) (history of fracture from osteoporosis or multiple risk factors for fracture) or who have failed or not tolerated other medications. Abaloparatide injection is also used to treat osteoporosis in men who are at high risk of fracture or who have failed or not tolerated other medications. Abaloparatide injection contains a synthetic form of a natural human hormone called parathyroid hormone (PTH). It works by causing the body to build new bone and by increasing bone strength and density (thickness).
Are there other uses for this medicine?
This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
How should this medicine be used?
Abaloparatide injection comes as a solution (liquid) to inject subcutaneously (under the skin). It is usually given once a day. Use abaloparatide injection at around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Use abaloparatide injection exactly as directed. Do not use more or less of it or use it more often than prescribed by your doctor.
You can inject abaloparatide injection yourself or have a friend or relative perform the injections. Before you use abaloparatide injection yourself the first time, carefully read the manufacturer's instructions. Ask your doctor or pharmacist to show you or the person who will be injecting the medication how to inject it. Be sure to ask your pharmacist or doctor if you have any questions about how to inject this medication.
Abaloparatide injection comes in a pen that contains enough medication for 30 doses. Do not transfer the medication to another syringe. Dispose of your pen 30 days after first opening even if it still contains unused medication.
You should inject abaloparatide injection into the lower stomach area. Avoid giving your injection within the 2-inch area around your belly button. Talk to your doctor about how to change your injection site for each injection. Do not give abaloparatide injection into your veins or muscles. Do not inject into areas where the skin is tender, bruised, red, scaly, hard, or where you have scars or stretch marks.
Always look at your abaloparatide injection before you inject it. It should be clear and colorless. Do not use abaloparatide injection if it has particles in it, or if it is cloudy or colored.
Be sure you know what other supplies, such as needles, you will need to inject your medication. Ask your doctor or pharmacist what type of needles you will need to inject your medication. Never reuse needles and never share needles or pens. Always remove the needle right after you inject your dose. Throw away needles in a puncture-resistant container. Ask your doctor or pharmacist how to dispose of the puncture-resistant container.
You should know that abaloparatide injection may cause dizziness, lightheadedness, and fainting when you get up too quickly from a lying position as well as a fast or pounding heartbeat and nausea. This usually occurs within 4 hours after receiving your dose and generally goes away within a few hours. You should receive your first several doses of abaloparatide injection where you can sit or lie down right away if necessary.
Your doctor may recommend calcium and vitamin D supplements to take during your treatment.
Abaloparatide injection controls osteoporosis but does not cure it. Continue to use abaloparatide injection even if you feel well. Do not stop using abaloparatide injection without talking to your doctor.

What should I know about storage and disposal of this medication?
Keep this medication in the container it came in, tightly closed, and out of reach of children. Before the first use, store abaloparatide pens in the refrigerator, but do not freeze them. After the first use, store your abaloparatide pen for up to 30 days at room temperature. Discard the pen after 30 days at room temperature.
It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org
Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website ( http://goo.gl/c4Rm4p ) for more information if you do not have access to a take-back program.
What other information should I know?
Keep all appointments with your doctor and the laboratory. Your doctor will order certain lab tests to check your body's response to abaloparatide injection.
