Denosumab is a targeted therapy that interferes with bone‑resorbing pathways, providing benefit in several bone‑related conditions.

- Osteoporosis (post‑menopausal): reduces vertebral, hip and non‑vertebral fracture risk. - Osteoporosis (male, high risk): lowers incidence of fractures in men with established bone loss. - Bone loss associated with glucocorticoid therapy: prevents loss of bone mineral density in patients receiving long‑term steroids. - Giant cell tumor of bone (recurrent or unresectable): delays disease progression and reduces need for surgery. - Hypercalcemia of malignancy (refractory): lowers serum calcium levels when other treatments have failed.

Adverse reactions to denosumab vary in frequency and severity.

Common Side Effects: - Injection site reactions: redness, pain or swelling at the injection site. - Musculoskeletal pain: aches in joints, muscles or bones. - Upper respiratory tract infection: mild cold‑like symptoms. - Dermatologic reactions: rash or eczema‑like eruptions. - Hypocalcemia: low blood calcium levels, often asymptomatic.

Serious or Rare Side Effects: - Osteonecrosis of the jaw (ONJ): exposed bone in the jaw that fails to heal. - Atypical femoral fractures: unusual breaks in the thigh bone. - Severe hypocalcemia: symptomatic low calcium requiring urgent treatment. - Severe hypersensitivity reactions: anaphylaxis or angioedema. - Infections requiring hospitalization: serious bacterial or fungal infections.

Denosumab should be used with careful clinical assessment and monitoring.

- Calcium and vitamin D supplementation: ensure adequate intake to reduce hypocalcemia risk. - Renal impairment: assess kidney function before initiating therapy. - Prior radiation therapy to the jaw: evaluate risk of osteonecrosis of the jaw. - Concomitant anti‑resorptive therapy: avoid overlapping use with bisphosphonates. - Pregnancy and lactation: contraindicated; discuss alternatives with a specialist. - Store at 2-8°C: keep refrigerated, protect from light, do not freeze or shake.

Denosumab may interact with several medicines, affecting safety or efficacy.

Major Interactions (Avoid): - Calcium‑containing antacids within 4 h of injection: may reduce absorption. - High‑dose vitamin D supplementation: can exacerbate hypercalcemia after discontinuation.

Moderate Interactions (Monitor Closely): - Bisphosphonates: overlapping anti‑resorptive effects increase risk of ONJ. - Immunosuppressants: may heighten infection risk. - Hormone replacement therapy: may alter calcium metabolism. - Anticoagulants: monitor for bleeding if severe hypocalcemia occurs. - Concomitant chemotherapy: assess infection risk regularly.
