What side effects does Xgeva (denosumab) cause?
Xgeva (denosumab) is associated with several well-known adverse effects, with some risks that can be serious in certain patients. The most prominent include:
- Low calcium levels (hypocalcemia), which can cause numbness/tingling, muscle cramps or spasms, and in severe cases more serious symptoms [1]
- Bone problems in the jaw (osteonecrosis of the jaw, ONJ), especially in people with cancer who receive bone-directed therapies [1]
- Bone healing delays and fractures can occur, and atypical femur fractures have been reported [1]
- Severe infections can occur in some patients, and Xgeva can also lower immunity-related measures in certain contexts [1]
What are the most common side effects?
Commonly reported side effects include fatigue and pain, along with laboratory changes such as low calcium levels [1]. The exact rate of each side effect can vary by the underlying condition being treated and patient factors.
What are the serious risks patients ask about most?
Patients and clinicians often focus on three high-stakes complications:
Osteonecrosis of the jaw (ONJ)
ONJ is a serious condition affecting the jawbone. Risk is higher with invasive dental procedures (such as tooth extractions) and in people with cancer receiving bone-targeted treatment [1].
Hypocalcemia (low blood calcium)
Xgeva can lower blood calcium, especially in patients with low vitamin D, kidney impairment, or other risk factors. Clinicians often check calcium and vitamin D and may recommend supplementation to reduce risk [1].
Atypical femur fractures
Long-term suppression of bone remodeling has been linked to atypical fractures of the femur in some patients. Warning symptoms can include new thigh or groin pain [1].
What happens if you stop Xgeva?
Stopping can cause rebound effects in bone turnover. This can increase the risk of fractures in some settings, so discontinuation should be discussed with the treating oncologist or clinician rather than done abruptly [1].
What should patients do to reduce risk?
Clinicians commonly manage side effects by:
- Checking calcium (and often vitamin D) and correcting deficiencies before and during treatment [1]
- Encouraging good oral hygiene and coordinating dental work ahead of time to reduce ONJ risk [1]
