It is important that your doctor check your progress at regular visits to make sure denosumab is working properly. Blood tests may be needed to check for unwanted effects.
Prolia® contains denosumab which can also be found in Xgeva®. Patients using Prolia® should not receive Xgeva®.
Your unborn baby could be harmed if you use denosumab while you are pregnant. Women receiving Xgeva® should use an effective form of birth control to keep from getting pregnant during treatment and for at least 5 months after the last dose. There is also a potential for denosumab to cause birth defects if the father is using it when his sexual partner becomes pregnant. If a pregnancy occurs while you are receiving denosumab, tell your doctor right away.
denosumab may cause serious allergic reactions, including anaphylaxis. Anaphylaxis can be life-threatening and requires immediate medical attention. Tell your doctor or nurse right away if you have a rash, lightheadedness, dizziness, or fainting, itching, swelling of the face, tongue, and throat, trouble breathing, or chest pain after you get the injection.
denosumab may cause hypocalcemia (low calcium in the blood). A low blood calcium must be treated before you receive denosumab. Call your doctor right away if you have muscle spasms or twitching, or numbness or tingling in your fingers, toes, or around your mouth.
Prolia® may increase your risk of developing infections. Avoid being near people who are sick or have infections while you are using denosumab. Check with your doctor right away if you have a fever or chills, red, swollen skin, severe abdominal or stomach pain, or burning or painful urination.
Skin problems may occur after receiving Prolia®. Check with your doctor right away if you have any of the following symptoms that do not go away or get worse: blistering, crusting, irritation, itching, or reddening of the skin, cracked, dry, or scaly skin, rash, or swollen skin.
It is important that you tell all of your doctors that you are receiving denosumab injection, including your dentist. If you are having dental procedures while receiving denosumab, you may have an increased chance of having a severe problem with your jaw. Make sure you tell your doctor or dentist about any new problems, such as pain or swelling, with your teeth or jaw.
The needle cover of the prefilled Prolia® syringe contains dry natural rubber (a derivative of latex), which may cause allergic reactions in people who are sensitive to latex. Tell your doctor if you have a latex allergy before you start using denosumab.
