How does this medication work? What will it do for me?
Denosumab belongs to a family of medications known as monoclonal antibodies. Specifically, it inhibits a protein that your body uses to signal for removing old bone tissue. Denosumab works by reducing the amount of bone your body breaks down, making your bones less likely to break.
Denosumab is used to treat osteoporosis for postmenopausal people who have a high risk of fracture or who have not tolerated or responded to other osteoporosis medications. It is also used to increase bone mass in people who have osteoporosis and are at high risk of having a fracture, have a history of osteoporotic fracture, or have not tolerated or responded to other osteoporosis medications.
This medication is also used to increase bone mass for people who are being treated with an aromatase inhibitor for breast cancer that has not spread to other parts of the body. It is also used to increase bone mass and reduce fractures for people who have prostate cancer that has not spread to other parts of the body and who are receiving medication to reduce testosterone levels.
Denosumab may also be used to increase bone mass for people who are taking or have just started to take glucocorticoids (e.g., prednisone, dexamethasone) for a long period of time.

Are there any other precautions or warnings for this medication?
Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Allergic reactions: In rare cases, a severe allergic reaction called Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS syndrome) may occur. This reaction may include fever, swollen glands, yellowing of the skin or eyes, flu-like symptoms with skin rash or blistering, or effects on other organs. These reactions are medical emergencies. Get immediate medical attention if you have symptoms of a severe allergic reaction.
Calcium and vitamin D: While using this medication, you need to receive enough calcium and vitamin D to maintain blood calcium levels. Your doctor will recommend a dose of calcium and vitamin D based on your needs. Contact your doctor immediately or get immediate medical attention if you develop symptoms of low blood calcium levels while using this medication (muscle spasms, twitches, or cramps; numbness or tingling in the fingers, toes, or around the mouth).
Fractures: As with other medications in this class, denosumab may contribute to a type of rare fracture of the long bone in the thigh (femur) without any form of trauma. If you experience new or unusual pain in the groin, hip, or thigh area, contact your doctor as soon as possible. Fractures of the bones in the spine (vertebra) have been reported after stopping this medication. Do not stop treatment with this medication without checking with your doctor first.
Infections: This medication may cause infections that in some cases are serious and require hospitalization. Contact your doctor at once if you develop signs of an infection such as fever, abdominal pain, earache, painful urination, or blood in urine, or if you notice a red, swollen, or tender area on the skin. People who are taking medications that suppress the immune system (e.g., tacrolimus, prednisone, azathioprine, anticancer medications) or who have a suppressed immune system may be more at risk of developing infections.
Severe jawbone problems: Denosumab may cause problems with your upper and or lower jaw. You may be at a higher risk of these problems if you have cancer that has spread to the bones, are taking certain medications (e.g., prednisone, anticancer medications), are having radiation treatments, have poor oral hygiene, or are having a tooth extracted. Your doctor may recommend that you see a dentist before starting this medication. It is important to practice good oral hygiene while taking this medication.
Pregnancy: Denosumab is only recommended for postmenopausal people and has not been studied for use during pregnancy. Anyone who could become pregnant must use highly effective birth control measures while taking this medication and for at least 5 months after the last dose of denosumab, to avoid becoming pregnant while using this medication. If you become pregnant while using this medication, contact your doctor immediately.
Breast-feeding: Denosumab has not been studied for use by people who are breast-feeding. It is not known if denosumab passes into breast milk. If you are breast-feeding and are taking this medication, it may affect your baby. Denosumab is not recommended for use by people who are breast-feeding.
Children and adolescents: The safety and effectiveness of using this medication have not been established for children.
