Tymlos (abaloparatide) is a medication used for osteoporosis in men and postmenopausal women at high risk for breaking bones (fractures). It's given once per day as an injection under the skin. This medication can't be used for longer than 2 years because of a theoretical risk of causing bone cancer.
Osteoporosis in women who have gone through menopause (postmenopause)
Osteoporosis in men
Tymlos (abaloparatide) is a parathyroid hormone (PTH) analog. This means it acts just like the PTH your body normally makes. PTH is a hormone that's important in balancing bone breakdown and formation to keep your bones healthy. When Tymlos (abaloparatide) attaches to the PTH receptors in your body, it promotes bone formation and causes your bones to become stronger. This lowers your risk for bone fractures or breaks.

Side effects that you should report to your care team as soon as possible:
Side effects that usually do not require medical attention (report these to your care team if they continue or are bothersome):
Available as a pre-filled pen with 30 doses
Good choice for men and postmenopausal women with osteoporosis at high risk for fracture or who've previously tried other osteoporosis medications
Can keep at room temperature after its first use for up to 30 days, making it convenient to take it on the go
Needs to be injected under the skin once per day
Not approved for osteoporosis from long-term corticosteroid use
Can't use for longer than 2 years
Make sure your provider or pharmacist teaches you how to give yourself Tymlos (abaloparatide) so that you avoid accidentally hurting yourself or wasting the medication. Read the directions or watch the instructional video on how to give yourself Tymlos (abaloparatide) injections under the skin. Contact your provider or pharmacist if you have any questions on how to use this medication.
Store unused Tymlos (abaloparatide) pens in the refrigerator. After using the pen for the first time, you can keep it at room temperature for up to 30 days.
When you first start using Tymlos (abaloparatide), make sure to sit down when you're giving yourself the injection and get up slowly afterwards. The medication can make you feel dizzy when you stand up too fast after sitting or lying down. This usually happens within 4 hours of injecting Tymlos (abaloparatide) during the first few times, but it should get better as you continue treatment.
When you start a new pen, you'll need to prime it to remove air bubbles before using it for the first time. You only need to prime each pen once. Contact your provider or pharmacist if you have any questions on how to prime this medication.
Each Tymlos (abaloparatide) pen will last you about a month because it contains 30 doses. But you'll need to use a new pen needle for each injection. This helps prevent infection.
If you drop your Tymlos (abaloparatide) pen and it isn't damaged, wipe it with a clean, damp cloth and continue using it. If the pen looks like it's damaged, don't use it. Call your provider, pharmacist, or the manufacturer at 1-855-672-3487 to get a replacement.
Throw away your needles (after each use) and pens (30 days after you first use it) in a sharps container or something made of heavy-duty plastic, such as an empty milk carton or laundry detergent bottle. Don't throw away them away in your trash can. These steps help lower your risk of needle-stick injuries. For more information on how to throw away your sharps container safely and guidance for your specific state, visit the FDA's website.
Ask your provider or pharmacist to see if you qualify for a savings program that can lower your out-of-pocket costs for Tymlos (abaloparatide).
Tymlos (abaloparatide) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Risk factors: Certain bone diseases (e.g., rickets, Paget's disease) | History of bone cancer or cancer that has spread to the bones | History of radiation therapy to the bones | Inherited conditions with higher risk of bone cancer | Using Tymlos (abaloparatide) for longer than 2 years
Although rare, there have been reports of people taking a medication similar to Tymlos (abaloparatide) who developed bone cancer (osteosarcoma).
Additionally, Tymlos (abaloparatide) caused bone cancer in some animals that received much higher doses of the medication than what's typically used in humans. But it's not known if Tymlos (abaloparatide) can cause or raise the risk of bone cancer. The risk of bone cancer when the medication is used any longer than 2 years also hasn't been studied. Because of this risk, Tymlos (abaloparatide) can't be used for longer than 2 years and shouldn't be used in people who are at higher risk of bone cancer.
Tymlos (abaloparatide) can suddenly drop your blood pressure if you get up too fast after sitting or lying down (orthostatic hypotension). This usually happens within 4 hours of injecting the medication and is more common with the first few doses. It should get better as you continue using the medication. For the first few doses, sit down when you're giving yourself Tymlos (abaloparatide) to prevent accidental injuries in case this happens. Get up slowly and hold onto something for support. If you suddenly become dizzy, feel like your heart is pounding or racing, or become nauseous, sit or lie down so you don't fall.
Risk factors: Too much calcium or vitamin D intake | History of high blood calcium levels | Medical conditions that raise calcium levels (e.g., high blood PTH levels, certain cancers)
Tymlos (abaloparatide) can cause your blood calcium levels to become too high. You're at risk for high calcium levels if you take Tymlos (abaloparatide) and your intake of calcium and vitamin D is too high or if you have medical conditions that raise your calcium levels. Your provider might regularly check your calcium levels through blood tests during treatment with Tymlos (abaloparatide).
Only take calcium and vitamin D supplements with Tymlos (abaloparatide) if your prescriber told you to do so. Also, make sure your provider knows about all your medical conditions and the medications you take. If you experience symptoms of high calcium levels, such as muscle weakness, nausea, vomiting, loss of appetite, low energy, or confusion, while taking Tymlos (abaloparatide), contact your provider right away.
Risk factors: Current or history of kidney stones | History of high calcium levels in your urine
Along with high blood calcium levels, Tymlos (abaloparatide) can also raise the calcium levels in your urine. In general, having too much calcium in the urine can lead to kidney stones to form. It isn't clear if Tymlos (abaloparatide) raises your risk of getting kidney stones if you've had any before. If you experience symptoms of kidney stones (e.g., low back pain, nausea, vomiting, dark-colored urine), contact your provider. They might measure the amount of calcium in your urine.
The typical dose is 80 mcg injected under the skin once a day.
