Denosumab
About Denosumab
Denosumab is an injection used to treat osteoporosis and strengthen thinning bones. It is prescribed to help reduce the risk of fractures in people who have a high chance of breaking bones. This medicine helps maintain bone density, especially in postmenopausal women and men undergoing certain cancer treatments.
This medicine is typically injected at regular intervals as decided by your healthcare provider. Because it is given as an injection, it does not need to be taken with meals, meaning food does not affect how it works in your body. To support your bones while using this treatment, your doctor may suggest adding calcium and vitamin D supplements to your daily routine, alongside light weight-bearing exercises.
While using Denosumab, some people may experience mild side effects like back pain, muscle stiffness, or joint discomfort. However, you must contact your doctor immediately if you notice serious symptoms, such as severe jaw pain, unusual pain in your thigh or groin, or signs of low blood calcium levels like muscle twitching or numbness.
Do not take this if you have untreated low levels of calcium in your blood. Before starting treatment, tell your doctor if you have severe kidney disease, a weak immune system, or are scheduled for any dental procedures. This medicine is not suitable for individuals who have unresolved dental or jawbone issues.
This injection may interact with other bone therapies or medicines that suppress your immune system, which can increase your risk of infections. If you are pregnant, planning to become pregnant, or breastfeeding, you should not use this medicine as it can harm the developing baby. Elderly individuals should consult their doctor to ensure their kidney function is monitored during treatment.

Patients Concern
Disease/Condition Glossary
Osteoporosis: It is a bone disease that weakens and thins the bones by decreasing bone density. As the density of bones decreases, they weaken and are more likely to break. Postmenopausal women are more likely to develop osteoporosis than men because, at menopause, women’s ovaries stop producing oestrogen (a female hormone) that is essential to keep bones healthy. Following menopause, bone loss occurs, making bones weak and more likely to break. Osteoporosis can also occur in men due to ageing and/or low levels of testosterone hormone. Signs and symptoms include back pain caused by a fractured or collapsed vertebra, loss of height over time, a stooped posture, bones that break much more easily than expected.
FAQs
Denosumab is used to treat osteoporosis in postmenopausal women and men who have an increased risk of fracture. It is also used to treat bone loss and reduce the risk of fractures.
Denosumab binds to a protein on RANK ligand on osteoclast (cells that cause bone breakdown) and inhibits their formation, functioning and survival. Thereby decreases bone breakdown, increases bone density, and strengthens the bone. Denosumab makes the bones stronger and less likely to break.
Osteonecrosis of the jaw (bone damage in the jaw) might be a side-effect of Denosumab. The risk increases in people taking Denosumab for longer durations. It might also occur upon discontinuation of the treatment. Maintain good dental hygiene and receive regular dental check-ups whilst on treatment with Denosumab. Inform your doctor if you have dental problems, gum disease, planned tooth extractions, cancer, if you smoke, or are taking bisphosphonates or corticosteroids.
Breakdown of bones releases calcium and causes hypercalcemia (high calcium levels in the blood). Denosumab helps treat high calcium levels by decreasing bone breakdown.
Unusual thigh bone fractures might occur whilst on treatment with Denosumab. Consult your doctor if you experience new or unusual pain in the thigh, hip, or groin.
Denosumab treats giant cell tumour of bone (GCTB) by blocking certain receptors in the tumour cells, thereby slows the tumour growth. Giant cell tumour of the bone is a non-cancerous tumour that typically grows at the ends of long bones.
Denosumab might cause skin infections. Consult your doctor immediately if you notice symptoms such as swollen skin, redness, cellulitis (hot and tender skin), commonly in the lower leg with feverish symptoms.
Denosumab has been used safely for up to 8 years, showing substantial increases in bone density during that time. However, the optimal duration of therapy varies depending on individual health conditions and needs. Long-term use should be closely monitored by your healthcare provider to assess benefits, risks, and the need for continued therapy. Always consult the doctor for personalized guidance.
Some people may experience hair loss while using Denosumab. However, individual reactions to medications can vary. If you experience hair loss or any unusual symptoms while taking Denosumab, consult the doctor to determine the cause and discuss appropriate management options.
No, Denosumab is not a chemotherapy medication. It is a monoclonal antibody which is used to treat conditions like osteoporosis, and bone loss associated with certain cancers, and to prevent bone fractures in patients with metastatic bone disease. It targets a protein called RANKL to inhibit bone breakdown, thereby increasing bone strength and density.
Denosumab is administered subcutaneously (under the skin) in your upper arm, upper thigh, or stomach area by the doctor or nurse, usually given once every 6 months for osteoporosis. Your doctor will determine the exact schedule based on your condition. Always follow the doctor's instructions regarding dosage and scheduling, as it may vary based on your specific medical condition.
You should inform your doctor before receiving Denosumab, as it is not recommended during pregnancy due to the potential risk of harm to the foetus.
Denosumab should be stored in a refrigerator at a temperature between 2°C and 8°C. Do not freeze it. Keep the vial in its outer carton to protect it from light.
The side effects of Denosumab include abdominal discomfort, bone/joint/muscle pain, arm/leg pain, constipation, and painful/frequent urination. Consult the doctor if any of these side effects persist or worsen.
Yes, most patients are advised to take calcium and vitamin D daily to prevent low blood calcium levels during treatment. Your doctor will recommend the right daily amount for you. Talk to your doctor before starting any new supplements.
Yes, it is highly recommended to have a dental exam and complete any major dental work before starting this medicine. This helps reduce the rare risk of developing serious jawbone problems. Talk to your doctor and dentist for personalised advice.
If you stop this treatment, your bone density can decrease rapidly, and your risk of bone fractures may return to what it was before starting. Never stop your treatment without a detailed discussion with your healthcare provider. Talk to your doctor about alternative options.
Yes, this medicine does not generally affect your ability to drive or operate machinery. However, if you feel dizzy or unwell after your injection, avoid driving until you feel better. Talk to your doctor if you experience unusual symptoms.
