General adverse events

The more commonly reported side effects have included arthralgia, pain, and nausea.

Hypersensitivity

• Rare (less than 0.1%): Anaphylaxis, possible allergic events soon after injection (e.g., acute dyspnea, oro/facial edema, generalized urticaria, chest pain, edema (mainly peripheral)
• Postmarketing reports: Drug hypersensitivity, angioedema, urticaria^[Ref]

Oncologic

• Frequency not reported: Osteosarcoma^[Ref]

Cases of bone tumor and osteosarcoma have been reported during the postmarketing period; however, an increased risk of osteosarcoma was not observed in observational studies. Two osteosarcoma surveillance safety studies (US claims-based database studies) designed to assess the incidence rate of osteosarcoma showed 3 osteosarcoma cases among 379,283 patients and zero cases among 153,316 patients receiving this drug. A similar risk for osteosarcoma has been observed with comparators. The interpretation of these results suggests caution as data sources do not allow for complete measurement and control for confounders.^[Ref]
