Prolia
Prolia (denosumab) is an injection that's used to treat osteoporosis in adults at high risk of fracture. It's also for those at high risk of fractures from certain cancer medications. It works as a monoclonal antibody called a RANKL inhibitor to strengthen your bones. Prolia (denosumab) is a convenient option because you only need an injection every 6 months. It's injected under the skin by a healthcare professional at a medical office. Side effects include back and muscle pain. It also has a risk of causing dangerously low calcium levels.

- Bone loss in women at high risk of fracture taking certain breast cancer medications
How Prolia (denosumab) works
Prolia (denosumab) is a monoclonal antibody known as a RANKL inhibitor. It works by blocking a protein in your body called RANK ligand (RANKL). This protein plays a role in breaking down your bones.
By blocking RANKL, Prolia (denosumab) helps strengthen your bones and prevent bone loss.

Pharmacist tips for Prolia (denosumab)
- It's important to take calcium and vitamin D supplements every day while taking Prolia (denosumab). This will help keep your bones healthy and strong. Most people will need at least 1,000 mg of calcium and 400 IU (international units) of vitamin D each day. Follow your prescriber's instructions for these supplements. Ask them if you're not sure how much calcium and vitamin D you need.
- You'll need to go to the medical office every 6 months to get your Prolia (denosumab) injection. Write the date and time of your appointments on your calendar to help you remember. Ask your prescriber about any flexibility if you need to get your injection a little early or late.
- If you miss a Prolia (denosumab) injection, make a new appointment as soon as you can to get it. Your next injection will be 6 months after that.
- Practice good mouth hygiene, like brushing and flossing your teeth each day. Remember to get your dental cleanings as scheduled. This helps lower your risk of having jawbone problems with Prolia (denosumab).
- If you need to get any dental work done, let your dentist or oral surgeon know you're taking Prolia (denosumab). You might be at risk of getting jawbone problems. Your care team can talk to you about the risks and benefits.
- Don't stop taking Prolia (denosumab) or skip injections without talking to your prescriber. Otherwise, you can be at risk of breaking a bone, including in your spine.
- If you can become pregnant and are having sex, use a reliable form of birth control while taking Prolia (denosumab). Keep using birth control for at least 5 months after you stop the medication. Prolia (denosumab) can harm an unborn baby. Let your prescriber know right away if you get pregnant while taking this medication.
Common questions about Prolia (denosumab)
It's not always clear when side effects from Prolia (denosumab) will start because everyone is different. Some people might feel mild pain in their back, arms, legs, muscles, or joints. Others might have more severe pain that can happen days or even months after the injection. There's also a rare risk of thigh bone fractures. This can feel like a dull ache in your hip, thigh, or groin lasting weeks or months. If you notice any new or unusual hip, thigh, or groin pain, call your care team to check it out. Also talk to your care team if you have other side effects that won't go away or bothers you a lot.
You'll get Prolia (denosumab) as an injection under the skin once every 6 months. A trained healthcare professional will help inject it usually at their clinic or office. It's injected into your upper arm, upper thigh, or stomach. Check with your prescriber about your options on how to get your Prolia (denosumab) injection.
No, Prolia (denosumab) isn't a bisphosphonate. It's a different type of medication called a monoclonal antibody. Both types can help treat osteoporosis, but they work in different ways. Bisphosphonates like alendronate (Fosamax) are usually the first choice. But your prescriber might choose Prolia (denosumab) instead if you have side effects you can't tolerate from bisphosphonates. Ask your prescriber which type of osteoporosis medication is right for you.
Based on current research, Prolia (denosumab) isn't known to cause cancer. Some people with cancer might need to take this medication. This includes women taking certain medications for breast cancer who are at high risk of fractures. It also includes men taking certain medications for prostate cancer with a high risk of breaking a bone. Prolia (denosumab) can help make their bones stronger and prevent fractures. Talk to your prescriber if you have other questions about this.
There are rare reports of people who had hair loss after starting Prolia (denosumab). It's not clear whether this hair loss was caused by Prolia (denosumab). More research is needed to explore about hair loss and this medication. If you notice any concerning hair loss while taking Prolia (denosumab), let your care team know. They can help you figure out what's causing it.
You can keep taking Prolia (denosumab) as long as it helps your bones and doesn't cause serious side effects. You only need one Prolia (denosumab) injection every 6 months. It keeps working over time to make your bones stronger and lower your chance of fractures. Before deciding to stop Prolia (denosumab), talk to your prescriber. They can help come up with a plan to keep your risk of fracture low. Ask your prescriber how long you should take Prolia (denosumab).
Prolia and and Xgeva are both medications with the same active ingredient: denosumab. They're both injections given under the skin. But they can't be used in place of one another. This is because the medications treat different conditions and have different dosing. Prolia helps treat osteoporosis in certain people who are at high risk of fracture. It's given once every 6 months. But Xgeva is used to help with bone or calcium issues related to certain cancers, like multiple myeloma. It's given once a month at a higher dose than Prolia. You shouldn't take Prolia and Xgeva at the same time because it can raise your risk of side effects. Ask your prescriber if you have more questions about differences between these medications.
Prolia (denosumab) and Evenity (romosozumab) are both injections under the skin for osteoporosis. But they have some differences. Both can help postmenopausal women who have a high risk of fractures. But Prolia can also be used for men with osteoporosis, osteoporosis caused by steroid use, and people taking certain cancer medications. In addition, Prolia is given once every 6 months for as long as needed. Evenity is given once a month but only for up to 1 year. Evenity also has a rare risk of heart problems, so it might not be right for people with heart issues. Ask your prescriber to compare and see which is best for you.

Risks and warnings for Prolia (denosumab)
Prolia (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.
Dangerously low calcium levels
- Risk factors: Serious kidney problems, with or without mineral and bone disorder | Receiving dialysis | History of hypoparathyroidism (low levels of parathyroid hormone) | Conditions that affect how well your body absorbs minerals | Previous surgery to remove your small intestine | Previous thyroid surgery | Taking other medications that can lower calcium levels
Prolia (denosumab) can cause your calcium levels to drop too low, which can be dangerous. This can sometimes last for weeks or even months. The risk is higher if you have serious kidney problems, especially with mineral and bone issues. It's also higher if you take medications that lower calcium levels, like diuretics.
Before starting Prolia (denosumab), your prescriber might check your calcium levels. If they're too low, you'll need to get that treated first. Then after each Prolia (denosumab) injection, your prescriber will check your calcium and mineral levels within 2 weeks. They'll keep checking your calcium weekly for the first month after the injection, and then monthly.
It's important to take calcium and vitamin D supplements while taking Prolia (denosumab). This helps keep your calcium levels within a safe range. Tell your care team if you notice signs of very low calcium. Look out for confusion; muscle spasms or cramps; or numbness and tingling in the mouth, hands, and feet.
Risk of fractures in the thigh bone
- Risk factors: Taking steroids
It's possible for people taking Prolia (denosumab) to have unusual fractures in the thigh bone. This can sometimes happen without any falls or injuries to the area. It's not clear if Prolia (denosumab) is the cause of the fractures. Watch for any new or unusual hip, thigh, or groin pain. The pain can feel dull or aching. If this happens, go to urgent care right away. The care team can check for any fractures.
Risk of spine fractures after stopping Prolia (denosumab)
- Risk factors: Stopping Prolia (denosumab) or skipping doses | History of fractures | History of osteoporosis
When you stop taking Prolia (denosumab) or miss doses, your risk of breaking a bone goes up. This includes the risk of having spine fractures. Spine fractures can happen as early as 7 months after stopping the medication. To lower your risk, you'll need to start another medication for osteoporosis after you stop Prolia (denosumab).
Make sure your prescriber knows if you've ever fractured your spine. They can help you under the risks and benefits of taking Prolia (denosumab).
Risk of serious infections
- Risk factors: Weak immune system | Taking medications that affect your immune system (such as transplant medications or steroids)
Some people taking Prolia (denosumab) have had serious infections. These can include skin, ear, stomach, bladder, or even heart infections (endocarditis). Sometimes, people had to get hospital care.
Your risk is higher if your immune system is weak. It's also higher if you take other medications that affect your immune system, like steroids and transplant medications.
Tell your prescriber if you have signs of an infection while taking Prolia (denosumab). Watch for fever, chills, cough, trouble breathing, red or swollen skin, serious stomach pain, or painful urination.
Risk of problems in the jawbone
- Risk factors: Oral or dental procedures | Cancer | Taking steroids or chemotherapy | Poor oral hygiene | History of gum problems | Anemia | Clotting problems | Infection | Wearing dentures that don't fit well | Taking Prolia (denosumab) for a long time
Although it's rare, some people taking Prolia (denosumab) have had a jawbone problem called osteonecrosis of the jaw (ONJ). This happens when the jawbone breaks down.
Talk to your prescriber about your risk of ONJ with Prolia (denosumab). It's more likely to happen if you've had dental work, poor mouth hygiene, gum problems, or wear dentures that don't fit. Your risk might also be higher if you have cancer, anemia, or blood-clotting problems. Additionally, it could be higher if you take steroids or get chemotherapy. Your prescriber might want you to get a dental exam before starting Prolia (denosumab).
To lower your risk of ONJ, practice good mouth hygiene. Brush and floss your teeth every day. And get dental exams when recommended. Be sure to tell your care team if you plan to have dental work while taking Prolia (denosumab). Also, let your dentist or oral surgeon know you take Prolia (denosumab). They can talk to you about the risks and benefits.
Call your prescriber or dentist right away if you have jaw pain, swelling, or drainage. These can be signs of ONJ.
Serious allergic reactions and skin reactions
Some people had a serious allergic or skin reaction while taking Prolia (denosumab). Get medical help if you have a serious rash, itching, or skin irritation. Also call 911 right away if you have swelling in your face or lips, trouble breathing, tight feeling in your throat, or other signs of anaphylaxis.
Severe bone, muscle, or joint pain
It's not common, but some people have had severe bone, muscle, or joint pain after starting Prolia (denosumab). This might happen anytime from a day to several months after you've begun treatment. Let your care team know if you have severe pain. They might consider other treatment options for you.
Don't take with Xgeva (denosumab)
Don't take Prolia (denosumab) if you're also taking Xgeva (denosumab) for bone or calcium problems from cancer. These medications both contain denosumab. Taking both at the same time can raise your risk of side effects.
