Xgeva (denosumab) is a RANKL inhibitor that helps prevent the breakdown of bones. It's used to prevent bone problems in adults with certain types of cancer, like breast cancer and prostate cancer, that have spread to the bones. It's also used to lower calcium levels in people who have cancer (hypercalcemia of malignancy). Xgeva (denosumab) is given as an injection under the skin, typically once per month by a healthcare professional (HCP). Common side effects of this medication include fatigue and nausea.
Prevention of broken bones in adults with multiple myeloma (MM) or cancer that has spread to the bones
Giant cell tumor of bone in adults and children ages 12 years and older who can't receive surgery
High calcium levels caused by cancer (hypercalcemia of malignancy) in adults
Xgeva (denosumab) is a monoclonal antibody that's classified as a RANKL inhibitor. By blocking the protein RANKL, Xgeva (denosumab) stops bones from being broken down by preventing cells called osteoclasts from working.

Works well at preventing bone loss, which prevents serious bone problems
Only need to get once a month (after the first month)
Injected by healthcare professional at their office
Can't be used if you’re pregnant or planning to become pregnant
Xgeva (denosumab) is injected under your skin once a month by a healthcare professional (HCP) in either your upper arm, upper thigh, or stomach area.
Mark your appointments on your calendar to get your Xgeva (denosumab) injections from your HCP or to get any blood tests (e.g., calcium and phosphate levels) done. It's important to get your injections on time so you don't miss any doses. Be sure to follow up regularly with your care team to discuss how treatment is going for you.
Your prescriber might recommend incorporating bone-healthy foods into your diet, exercising, and taking calcium and vitamin D supplements to help prevent your bones from weakening. Work with your prescriber on a plan that works best for you.
If you're having any dental procedures done, make sure to let your dentist or oral surgeon know you're taking Xgeva (denosumab) because it can cause jaw bone problems (called osteonecrosis of the jaw).
Tell your prescriber if you're taking Prolia (denosumab) for osteoporosis before starting Xgeva (denosumab). Both Prolia and Xgeva have the same active ingredient, denosumab. So you shouldn't be on both medications.
If you're pregnant, let your prescriber know right away. Xgeva (denosumab) can cause serious harm to your unborn baby. If you're able to get pregnant, make sure to use a reliable form of birth control during treatment with Xgeva (denosumab) and for at least 5 months after you stop the medication.
Ask your healthcare team about possible risks and benefits of receiving Xgeva (denosumab) while breastfeeding. There isn't much information about how this medication might affect a nursing child, but research shows low amounts of it can pass into breastmilk.
Xgeva (denosumab) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Risk factors: Serious kidney problems | Not taking calcium supplements | Taking other medications that can lower calcium blood levels | Conditions that affect how well your body absorbs minerals | Surgery to remove your small intestine | History of hypoparathyroidism (low levels of parathyroid hormone) or thyroid surgery
Xgeva (denosumab) can case dangerously low blood calcium levels, especially in people who have kidney problems and are taking medications for high parathyroid levels, such as cinacalcet (Sensipar) and Parsabiv (etelcalcetide).
Signs of low calcium include memory loss, muscle spasms or cramps, numbness and tingling in the hands, feet, and face. Your prescriber will monitor your calcium, phosphorus, and magnesium levels regularly during treatment, especially during the first weeks after you start Xgeva (denosumab). If needed, your healthcare team will prescribe calcium and vitamin D supplements to keep your calcium level within a safe range.
Risk factors: History of giant cell tumor of bone | Being at an age where your bones are still growing
Xgeva (denosumab) can cause dangerously high calcium levels for people who stop taking Xgeva (denosumab) for giant cell tumor of bone and in people whose bones are still growing. The risk is highest during the first year after you stop the medication. Let your prescriber know right away if you experience loss of appetite, stomach upset or pain, nausea, vomiting, and constipation.
Risk factors: Having oral or dental procedures done while taking Xgeva (denosumab) | Using dental devices | Taking steroid medications, certain medications that stop tumors from growing, or chemotherapy | Poor mouth hygiene | History of gum infections | History of diabetes
Although rare, Xgeva (denosumab) can cause osteonecrosis of the jaw, a condition where the jaw bone breaks down. This can cause symptoms like jaw pain, infection or inflammation in your jawbone, tooth or gum infection, or slow healing after a dental procedure. The risk of ONJ might be higher the longer you take Xgeva (denosumab).
To lower your risk of this side effect, practice good mouth hygiene, such as brushing and flossing your teeth multiple times per day and rinsing with fluoride. You might need a dental exam before you start Xgeva (denosumab) and occasionally while you're taking the medication. If you notice pain or swelling in your jaw, talk to your prescriber right away. If you have a dental procedure planned while you're taking this medication, let your prescriber know so you can discuss the risks and benefits of continuing this medication or having the procedure done.
Risk factors: Taking steroid medications
People taking Xgeva (denosumab) have experienced unusual thigh fractures, even without any falls or injuries occurring to the area. If you experience any new or unusual hip, thigh, or groin pain, let your healthcare team know so they can check you for any fractures.
Risk factors: Stopping Xgeva (denosumab) treatment or skipping doses | History of fractures | History of osteoporosis
When you stop taking Xgeva (denosumab) or skip doses, your risk of broken bones rises, including the risk of spine fractures. Before you start taking Xgeva (denosumab), let your prescriber know if you've ever fractured your spine so you can discuss the risks and benefits of taking this medication. To lower your risk of spine fractures, your prescriber might suggest you start another medication for osteoporosis after you stop taking Xgeva (denosumab).
Risk factors: Currently pregnant
Xgeva (denosumab) can cause serious and life-threatening harm to an unborn baby. Don't use Xgeva (denosumab) if you're pregnant. Before you start treatment, your healthcare team might ask you to take a pregnancy test to make sure you're not pregnant. It's important to use a reliable form of birth control while you're taking Xgeva (denosumab) and for at least 5 months after you stop the medication.
Some people who received Xgeva (denosumab) have reported serious allergic reactions, including trouble breathing, swelling of the throat and lips, and hives. Get medical help right away if you experience these symptoms. Also, let your healthcare team know about the reaction after you receive treatment; they'll ask you to stop Xgeva (denosumab) and consider other options.
Xgeva (denosumab) is given as an injection under the skin in the upper arm, upper thigh, or stomach.
Prevention of broken bones in people with MM or cancer that has spread to the bones: The typical dose is 120 mg injected under the skin every 4 weeks.
Giant cell tumor of bone and high calcium levels caused by cancer: The typical dose is 120 mg injected under the skin every 4 weeks. In the first month of treatment, you'll receive an additional 120 mg on Day 8 and 15.
Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. When you are receiving this medicine, it is especially important that your healthcare professional know if you are taking any of the medicines listed below. The following interactions have been selected on the basis of their potential significance and are not necessarily all-inclusive.
Using this medicine with any of the following medicines is usually not recommended, but may be required in some cases. If both medicines are prescribed together, your doctor may change the dose or how often you use one or both of the medicines.
