How Tymlos Works and How It’s Taken

Tymlos is a bone-building medicine. It works by turning on a receptor in the body called the PTH1 receptor. This increases the activity of cells that build new bone.

Doctors prescribe Tymlos:

  • To treat osteoporosis in postmenopausal women who are at high risk of breaking a bone, or who cannot use or did not do well with other available osteoporosis treatments. In these women, Tymlos can lower the risk of fractures in the spine and other bones.
  • To increase bone density in men with osteoporosis who are at high risk of breaking a bone, or who cannot use or did not do well with other available osteoporosis treatments.

Tymlos is injected under the skin once each day. It is given in the abdomen. Avoid injecting within 2 inches of the belly button, and use a different injection spot each day.

Take Tymlos at about the same time every day. Do not inject it into a vein or muscle. With proper training, it can be given at home.

Typical Dosing for Osteoporosis

The recommended dose of Tymlos is 80 micrograms injected under the skin once daily.

If you do not get enough calcium and vitamin D from your diet, your healthcare provider may recommend supplements.

Tymlos is not recommended for use for more than two years total during your lifetime.

This information is based on prescribing information, but your healthcare provider may tailor your treatment plan. Always follow their guidance.

Top Advice From Members on Tymlos

MHT logoThese insights are based on 970 comments about Tymlos from MyOsteoTeam members. These are the experiences of a small number of people and are not meant to be medical advice.
 

Members who use Tymlos often say the day-to-day routine gets easier with time, especially when they find a dosing schedule and injection setup that works for them. They also frequently mention keeping a close eye on side effects, staying in touch with their doctor about labs and follow-up scans, and planning ahead for cost and what comes after Tymlos.

  1. 1
    Try taking injections at night if side effects bother you.
    “If you decide to go on Tymlos, please give your body time to adjust to it. Many women give up with any side effect so I began taking it at night before bed and virtually no problems.”
  2. 2
    Keep track of side effects and tell your doctor.
    “My heart rate went up within 10 minutes of injection, and I buzzed for about half an hour or so. If I was really active, it might stay up a little longer. It really helps to know it might happen and be ready for it.”
  3. 3
    Get the training and support you need for self-injections.
    “A Tymlos educator came to my house and showed me how to inject. It was much easier than I had thought.”

Serious Side Effects and Warnings

  • Severe allergic reactions — These hypersensitivity reactions can include anaphylaxis, angioedema, or hives, which can cause trouble breathing, swelling of the face, lips, tongue, or throat, or rash.
  • Osteosarcoma risk — Osteosarcoma is a rare bone cancer seen in animal studies; it is unknown if this happens in people, and persistent bone pain or a new tender lump should be checked.
  • Orthostatic hypotension — A drop in blood pressure when you stand up can cause lightheadedness, dizziness, nausea, fast heartbeat, or palpitations.
  • Hypercalcemia — High blood calcium levels may need medical care.
  • Hypercalciuria and urolithiasis — High urine calcium and kidney stones can occur.

Get medical help right away if you think you are having a serious reaction.

Community FAQs

These answers are fact-checked by our editorial staff.

How effective is Tymlos for osteoporosis?

In an 18-month study of postmenopausal women with osteoporosis, 0.6 percent of women taking Tymlos had a new spine fracture compared with 4.2 percent of women taking a placebo.

After 18 months, women taking Tymlos had average increases in bone mineral density of 9.2 percent in the lower spine, 3.4 percent in the total hip, and 2.9 percent in the femoral neck, which is the upper part of the thigh bone near the hip.

In a 12-month study of men with osteoporosis, average bone mineral density increased by 8.5 percent in the lower spine, 2.1 percent in the total hip, and 3 percent in the femoral neck.

How long does Tymlos take to work for osteoporosis?

Studies measured changes in markers related to bone formation during treatment. In postmenopausal women, one bone-formation marker reached its highest average increase at month 1.

Bone mineral density improvements were measured after 12 months in men and 18 months in postmenopausal women. The study does not say exactly how soon an individual person will benefit from Tymlos.

What tests or monitoring are needed with Tymlos for osteoporosis?

If your healthcare provider thinks you may have kidney stones or high calcium in your urine, they may check your urine calcium level.

Tymlos can also raise calcium levels in the blood. The prescribing information does not give a routine blood calcium testing schedule for everyone, but your healthcare provider may decide what monitoring is needed based on your health.

Before each injection, check the Tymlos solution. Do not use it if it looks cloudy, colored, or has particles in it.
