Teriparatide injection causes osteosarcoma (cancer of the bones) in laboratory rats. It is possible that teriparatide injection may also increase the chances that humans will develop this rare but serious cancer. Because of this risk, teriparatide injection should not be used to prevent osteoporosis, to treat mild osteoporosis, or by people who can take other medications for osteoporosis. You should not use teriparatide injection unless you have osteoporosis and at least one of the following conditions is met: you have already had at least one bone fracture; your doctor has determined that you are at high risk of fractures; or you cannot take or do not respond to other medications for osteoporosis. Tell your doctor if you have or have ever had a bone disease such as Paget's disease, bone cancer or a cancer that has spread to the bone, or radiation therapy of the bones. Your doctor will order certain tests to see if teriparatide injection is right for you.
Your doctor or pharmacist will give you the manufacturer's patient information sheet (Medication Guide) when you begin treatment with teriparatide injection and each time you refill your prescription. Read the information carefully and ask your doctor or pharmacist if you have any questions. You can also visit the Food and Drug Administration (FDA) website ( Web Site) or the manufacturer's website to obtain the Medication Guide.
Talk to your doctor about the risks of using teriparatide injection.
Teriparatide injection is used to treat osteoporosis (a condition in which the bones become thin and weak and break easily) in men and in women who have undergone menopause ('change in life,' end of menstrual periods), who are at high risk of fractures (broken bones). This medication is also used to treat osteoporosis in men and women who are taking corticosteroids (a type of medication that may cause osteoporosis in some patients). Teriparatide injection contains a synthetic form of 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).
Teriparatide injection comes as a solution (liquid) to inject subcutaneously (under the skin) in your thigh or lower stomach area. This medication comes in prefilled dosing pens. It is usually injected once a day for up to 2 years. To help you remember to use teriparatide injection, use it 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 teriparatide 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 teriparatide injection yourself or have a friend or relative perform the injections. Before you use teriparatide injection yourself the first time, read the User Manual that comes with it. Ask your doctor or pharmacist to show you or the person who will be injecting the medication how to inject it. The User Manual includes solutions to problems you may have when you try to use teriparatide injection. Be sure to ask your pharmacist or doctor if you have any questions about how to inject this medication.
Teriparatide injection comes in a pen that contains enough medication for 28 doses. Do not transfer the medication to a syringe. Use a new needle for each injection. Needles are sold separately. Ask your doctor or pharmacist if you have questions about the type of needles to use. Dispose of used needles in a puncture-resistant container. Talk to your doctor or pharmacist about how to dispose of the puncture-resistant container.
Teriparatide injection controls osteoporosis but does not cure it. Continue to use teriparatide injection even if you feel well. Do not stop using teriparatide injection without talking to your doctor.
This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
Before using teriparatide injection,
You should eat and drink plenty of foods and drinks that are rich in calcium and vitamin D while you are using teriparatide injection. Your doctor will tell you which foods and drinks are good sources of these nutrients and how many servings you need each day. If you find it difficult to eat enough of these foods, tell your doctor. In that case, your doctor may prescribe or recommend a supplement.
Use the missed dose as soon as you remember it that day. However, if the day has already passed, skip the missed dose and continue your regular dosing schedule. Never inject more than one dose per day.
Teriparatide injection may cause side effects. Tell your doctor if any of these symptoms or those listed in the SPECIAL PRECAUTIONS section are severe or do not go away:
Some side effects can be serious. If you experience any of the following symptoms, call your doctor immediately:
Teriparatide injection may cause other side effects. Call your doctor if you have any unusual problems while using this medication.
If you experience a serious side effect, you or your doctor may send a report to the Food and Drug Administration's (FDA) MedWatch Adverse Event Reporting program online ( Web Site ) or by phone (1-800-332-1088).
Keep this medication in the pen it came in with the cap on and without a needle attached, tightly closed, and out of reach of children. Store it in the refrigerator but do not freeze it. Protect it from light. Dispose of the pen after 28 days of use, even if it is not empty.
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 ( Web Site) for more information if you do not have access to a take-back program.
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. Web Site
In case of overdose, call the poison control helpline at 1-800-222-1222. Information is also available online at Web Site. If the victim has collapsed, had a seizure, has trouble breathing, or can't be awakened, immediately call emergency services at 911.
Symptoms of overdose may include:
Keep all appointments with your doctor and the laboratory. Your doctor will order certain lab tests to check your body's response to teriparatide injection.
Before having any laboratory test, tell your doctor and the laboratory personnel that you are using teriparatide injection.
Do not let anyone else use your medication. Never share a teriparatide injection pen. Ask your pharmacist any questions you have about refilling your prescription.
It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
