Tymlos (abaloparatide) can cause several side effects, with the most common being nausea, dizziness, headache, and fatigue [1]. Other frequently reported side effects include abdominal pain, injection site reactions, and a decreased heart rate [2].
What are the serious risks associated with Tymlos?
A significant concern with Tymlos is the potential for osteosarcoma, a type of bone cancer. In studies, rats treated with abaloparatide had an increased incidence of osteosarcoma. While a definitive increase in osteosarcoma has not been established in humans, it is a risk that patients should be aware of [2]. Additionally, Tymlos can cause a significant decrease in blood pressure when a patient stands up after lying down, known as orthostatic hypotension. This can lead to dizziness or fainting and typically occurs shortly after the injection [1][2]. Patients are advised to sit or lie down for at least 30 minutes after taking Tymlos to mitigate this risk [2].
How does Tymlos affect heart rate?
Tymlos can cause a transient but significant decrease in blood pressure and heart rate, particularly within the first hour after injection. This effect is generally temporary and does not require discontinuation of the medication in most patients. However, close monitoring is recommended, especially for individuals with pre-existing cardiovascular conditions [1][2].
Who should not take Tymlos?
Tymlos is contraindicated in patients with hypersensitivity to abaloparatide or any of its excipients. It is also not recommended for individuals with Paget's disease of bone, unexplained elevations of alkaline phosphatase, or a history of bone radiation therapy. Patients with hypercalcemia or metastatic or bone cancer are also advised against using Tymlos [2].
How long is the treatment duration for Tymlos?
The recommended duration of treatment with Tymlos is generally limited to 18 months, with a maximum of 18 doses over a lifetime. Continuous use beyond 18 months has not been shown to provide additional bone mass benefits and may increase the risk of adverse effects, including osteosarcoma [2].
What are the alternatives to Tymlos for osteoporosis treatment?
Besides Tymlos, other medications are available for treating osteoporosis. These include bisphosphonates (such as alendronate, risedronate, and ibandronate), denosumab (Prolia), teriparatide (Forteo), and romosozumab (Evenity) [3]. Each of these treatments has its own mechanism of action, efficacy, and side effect profile.
