Prolia shot side effects?

What are the common side effects of Prolia shots?

Prolia, also known as denosumab, is a biologic medication injected every six months to treat osteoporosis, as well as to prevent fractures in patients with hormone receptor-positive breast cancer and bone metastases [1]. Like any medication, Prolia can cause side effects in some patients. According to Amgen, the manufacturer [2], the most common side effects of Prolia include:

* Joint pain or swelling (arthralgia/arthritis)
* Muscle pain or weakness
* Back pain
* Pain, swelling, or irritation at the injection site
* Fatigue

How quickly do Prolia side effects appear?

Most side effects occur within the first few months after starting Prolia treatment [3]. Joint pain and muscle pain are the most common side effects, and they can occur within a few weeks to a few months after the first injection.

Rare but serious side effects of Prolia

While rare, Prolia is associated with serious side effects, including:

* Increased risk of infection (e.g., osteonecrosis of the jaw, skin infections)
* Skin problems (e.g., dermatitis, eczema)
* Hypocalcemia (low calcium levels)
* Atypical femoral fractures (spontaneous fractures of the thigh bone)

Pre-existing conditions and increased risk of side effects

Patients with a history of kidney disease or renal impairment may be at an increased risk of experiencing side effects, particularly hypocalcemia. Additionally, Prolia may exacerbate pre-existing conditions such as osteopenia or osteoporosis in patients with hypocalcemia [4].

Managing and reducing side effects

To minimize the risk of side effects, patients should inform their healthcare provider about any previous medical conditions or concerns. Amgen recommends taking calcium and vitamin D supplements to help prevent hypocalcemia and other side effects.
