Possible side effects

Like all medicines, Prolia® (denosumab) can cause side effects, although not everybody gets them.
Uncommonly, patients receiving Prolia® may develop skin infections (predominantly cellulitis). Please tell your doctor immediately if you develop any of these symptoms while being on treatment with Prolia®: swollen, red area of skin, most commonly in the lower leg, that feels hot and tender, and possibly with symptoms of fever.
Rarely, patients receiving Prolia ® may develop pain in the mouth and/or jaw, swelling or non-healing of sores in the mouth or jaw, discharge, numbness or a feeling of heaviness in the jaw, or loosening of a tooth. These could be signs of bone damage in the jaw(osteonecrosis). Tell your doctor and dentist immediately if you experience such symptoms while being treated with Prolia ® or after stopping treatment.
Rarely, patients receiving Prolia ® may have low calcium levels in the blood (hypocalcaemia). Symptoms include spasms, twitches, or cramps in your muscles, and/or numbness or tingling in your fingers, toes or around your mouth and/or seizures, confusion, or loss of consciousness. If any of these apply to you, tell your doctor immediately. Low calcium in the blood may also lead to a change in heart rhythm called QT prolongation which is seen by electrocardiogram (ECG).
Rarely unusual fractures of the thigh bone may occur in patients receiving Prolia ®. Contact your doctor if you experience new or unusual pain in your hip, groin or thigh as this may be an early indication of a possible fracture of the thigh bone.
Rarely, allergic reactions may occur in patients receiving Prolia ®. Symptoms include swelling of the face, lips, tongue, throat or other parts of the body; rash, itching or hives on the skin, wheezing or difficulty breathing. Please tell your doctor if you develop any of these symptoms while being treated with Prolia ®.
