Prolia (generic name Denosumab) is an injectable medication primarily used to treat osteoporosis in postmenopausal women and men at risk for fractures. It is also used to treat bone loss in patients receiving certain cancer treatments, such as hormone therapy for prostate or breast cancer.
Prolia belongs to a class of drugs called RANK ligand inhibitors and works by targeting and inhibiting the action of a protein called RANK ligand. This protein plays a crucial role in the process of bone resorption, where bone cells break down bone tissue.

How Prolia Works
Prolia works by targeting the RANK ligand, a protein that binds to RANK receptors on osteoclasts, the cells responsible for the breakdown of bone. When RANK ligand binds to its receptor on osteoclasts, it stimulates the osteoclasts to become active and begin resorbing bone.
Prolia works by binding to RANK ligand, preventing it from binding to the RANK receptor, which reduces the activity of osteoclasts and the overall process of bone resorption.
This action helps to increase bone mineral density (BMD) and reduce the risk of fractures, which is particularly important in patients with osteoporosis or bone loss due to cancer treatments.
Prolia is administered as an injection every six months under the skin (subcutaneously), typically by a healthcare provider in a clinical setting.
Uses of Prolia
Prolia is primarily used to manage and treat osteoporosis and other bone-related conditions. Some of the main uses of Prolia include:
1. Osteoporosis in Postmenopausal Women and Men
Prolia is commonly used in postmenopausal women and men who are at high risk for fractures due to osteoporosis. Osteoporosis weakens the bones, making them fragile and more prone to breaks. By inhibiting bone resorption, Prolia helps increase bone strength and density.
2. Bone Loss Due to Cancer Treatment
Prolia is used in patients with cancer who are receiving treatments that affect bone health. For example, hormone therapy for breast cancer or prostate cancer can cause bone loss. Prolia can help reduce the risk of fractures in these patients by strengthening their bones.
3. Prevention of Bone Fractures in High-Risk Patients
For patients with conditions that affect bone density, such as those undergoing certain cancer treatments or individuals with bone metastases, Prolia can help prevent fractures, which are a common complication of these conditions.
How is Prolia Administered?
Prolia is administered as an injection given subcutaneously (under the skin), typically every six months. The injection is usually performed by a healthcare professional at a medical facility.
The usual dose of Prolia is 60 mg, which is given once every six months. The medication should be administered under the skin of the thigh, abdomen, or upper arm.
It is important for patients receiving Prolia to have regular calcium and vitamin D levels monitored, as Prolia can cause low calcium levels (hypocalcemia). In some cases, patients may need to take calcium and vitamin D supplements to help maintain healthy levels.
Potential Side Effects of Prolia
As with any medication, Prolia can cause side effects. Some of the more common and serious side effects include:
Common Side Effects:
- Back pain
- Joint pain or muscle pain
- Headache
- Bladder infections
- High cholesterol levels
Serious Side Effects:
- Osteonecrosis of the jaw (ONJ): This is a rare but serious condition in which the jawbone begins to die. It is more common in patients who have undergone dental procedures, such as tooth extractions, while receiving Prolia. Patients should inform their dentist and doctor about their Prolia treatment before any dental work.
- Fractures: In some cases, Prolia may cause atypical fractures, which are unusual fractures that occur with minimal trauma, particularly in the thigh bone.
- Low blood calcium: Prolia can lower blood calcium levels (hypocalcemia), leading to symptoms like muscle spasms, cramps, or numbness. Calcium and vitamin D supplements are often recommended to prevent this.
- Infections: Prolia can weaken the immune system, making patients more susceptible to infections, particularly in the urinary tract or respiratory system.
Contraindications and Cautions
Prolia should not be used in certain populations or with caution in others:
- Hypocalcemia (Low calcium levels): Prolia should not be used in patients with low blood calcium levels. It is important to correct low calcium levels before starting treatment.
- Pregnancy and Breastfeeding: Prolia is not recommended for use during pregnancy or breastfeeding, as it may harm the baby. Women should use effective contraception during treatment and for at least five months after stopping the drug.
- Infections: Prolia may increase the risk of infections, so patients with a history of frequent infections should use the drug cautiously and discuss potential risks with their healthcare provider.
- Dental Health: Patients receiving Prolia should maintain good oral hygiene and have regular dental check-ups. Osteonecrosis of the jaw (ONJ) is a potential risk, especially after dental surgery or extractions.
Monitoring and Follow-up
Patients receiving Prolia require regular monitoring to ensure safety and effectiveness. Key considerations include:
- Calcium and Vitamin D levels: Regular monitoring of calcium and vitamin D levels is essential to avoid hypocalcemia. If blood calcium levels are low, supplementation may be required.
- Dental exams: Given the risk of osteonecrosis of the jaw, patients should have routine dental check-ups and inform their dentist that they are receiving Prolia before undergoing any dental procedures.
- Fracture risk: Patients should report any unusual pain or fractures to their healthcare provider immediately.
Conclusion
Prolia (Denosumab) is an effective medication for treating osteoporosis and preventing bone fractures in high-risk individuals. By inhibiting bone resorption, Prolia strengthens bones, helping to reduce the risk of fractures in postmenopausal women, men, and cancer patients undergoing certain treatments. While the drug is generally well-tolerated, it can cause side effects such as low calcium levels, jawbone problems, and infections. Regular monitoring and preventive measures, such as calcium and vitamin D supplementation, are important for ensuring the safe and effective use of Prolia. Patients should always consult their healthcare provider to determine if Prolia is the right treatment option for their condition.
