Denosumab

Introduction

Denosumab is a prescription medication used to treat osteoporosis and prevent bone loss. It is commonly prescribed for postmenopausal women at risk of fractures and patients with bone-related conditions caused by cancer. Denosumab works by inhibiting the activity of osteoclasts, the cells responsible for bone breakdown, thereby increasing bone strength and reducing fracture risk.

Uses of Denosumab

• Treatment of osteoporosis in postmenopausal women
• Prevention of fractures in men and women with weak bones
• Treatment of bone loss due to hormone therapy in cancer patients
• Prevention of skeletal-related events in patients with bone metastases
• Management of giant cell tumors of bone

How Denosumab Works

Denosumab is a monoclonal antibody that targets and inhibits RANKL, a protein involved in bone resorption. By blocking RANKL, Denosumab reduces the activity of osteoclasts, preventing bone loss and increasing bone density, ultimately reducing the risk of fractures.

Benefits of Denosumab

• Increases bone strength and density
• Reduces the risk of fractures
• Prevents bone loss in cancer patients undergoing therapy
• Effective for osteoporosis management
• Convenient dosage schedule with long-lasting effects

How to Take Denosumab

Denosumab is administered as an injection under the skin (subcutaneously) by a healthcare professional. The usual dose is 60 mg every six months for osteoporosis and 120 mg every four weeks for cancer-related bone conditions. Patients should take calcium and vitamin D supplements as prescribed by their doctor.

Types of Dosage Available

• Pre-filled injection (60 mg for osteoporosis)
• Pre-filled injection (120 mg for bone metastases and tumors)

Side Effects of Denosumab

• Joint and muscle pain
• Low calcium levels (hypocalcemia)
• Skin infections (cellulitis)
• Back pain
• Increased risk of jawbone problems (osteonecrosis)
• Allergic reactions (swelling, rash, difficulty breathing)

Safety Advice

• Ensure adequate calcium and vitamin D intake during treatment
• Inform your doctor about any dental problems before use
• Do not take Denosumab if you have severe hypocalcemia
• Regularly monitor bone density and calcium levels
• Avoid use during pregnancy or breastfeeding unless prescribed
