Denosumab is used to treat bone problems that may occur with cancer that has spread to the bones or to treat high blood calcium levels (hypercalcemia) that may occur with cancer. It may also be used by adults (and teenagers who have reached their final adult height) to treat a certain disease called giant cell tumor of the bone, if they cannot use surgery to treat the disease. This medication should not be used in people with multiple myeloma.
This medication is given by injection under your skin in the upper arm, upper thigh, or abdomen by a healthcare professional as directed by your doctor, usually every 4 weeks. If you are using this medication to treat giant cell tumor of the bone or high blood calcium levels, your doctor may also direct you to receive additional doses once a week during weeks 2 and 3 of the first month of treatment.
Use this medication regularly in order to get the most benefit from it. Remember to receive it every 4 weeks. It may help to mark your calendar with a reminder.
Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
Denosumab may cause very serious (rarely fatal) low levels of calcium in the blood, especially if you have kidney problems. Take calcium and vitamin D as directed by your doctor. (See also How to Use section.) Get medical help right away if you have any symptoms of low calcium such as: severe muscle spasms/cramps, mental/mood changes (such as irritability or confusion), numbness/tingling (especially around lips/mouth or in fingers/toes), seizures, severe dizziness/fainting, fast/irregular heartbeat.
Denosumab can affect your immune system. You may be more likely to get a serious infection, such as a skin, ear, stomach/gut, or bladder infection.

Denosumab can cause skin problems such as dryness, peeling, redness, itching, small bumps/patches, or blisters. However, you may not be able to tell it apart from a rare rash that could be a sign of a severe allergic reaction. Therefore, get medical help right away if you develop any rash or if any of these symptoms persist or worsen.
Denosumab may cause high levels of calcium in the blood weeks to months after treatment has stopped, especially if you have not reached your final adult height. Tell your doctor right away if you have any symptoms of high calcium after you have stopped using denosumab such as: nausea, vomiting, headache, unusual tiredness.
A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.
