Patient Education Summary: Prolia (Denosumab) for Osteoporosis
What is Prolia and How Does It Work?
Prolia is a medication given as an injection under your skin every 6 months to strengthen your bones and prevent fractures. 1
- Prolia works by blocking a protein called RANKL that causes bone breakdown, helping your bones stay stronger and denser 1, 2
- In clinical trials, Prolia reduced spine fractures by 68%, hip fractures by 40%, and other fractures by 20% over 3 years 1, 3
- Your bone density will increase at the spine, hip, and other sites while taking this medication 1
How You Will Receive Prolia
- You will get a 60 mg injection under your skin (like a flu shot) once every 6 months 4, 1
- The injection is given by your healthcare provider in the office 1
- You must take calcium (at least 1000 mg daily) and vitamin D (at least 400-800 IU daily) supplements every day while on Prolia 1
Important Things You Must Do Before Starting Prolia
You must have a dental checkup before starting Prolia to identify any tooth or gum problems. 5, 6
- Tell your dentist you will be starting Prolia 5
- Complete any needed dental work before beginning treatment 5
- If you have kidney disease, you will need blood tests to check your calcium, vitamin D, and parathyroid hormone levels before starting 1
Common Side Effects
Most people tolerate Prolia well, with side effects similar to placebo in studies. 6, 3
Serious Side Effects to Watch For (Rare but Important)
Call your doctor immediately if you experience any of these symptoms: 5, 1
Low Calcium (Hypocalcemia)
- Muscle spasms, twitches, or cramps 1
- Numbness or tingling in fingers, toes, or around your mouth 1
- This is why you must take your calcium and vitamin D supplements every day 1
Jaw Problems (Osteonecrosis of the Jaw)
- Jaw pain, swelling, or numbness 5
- Loose teeth 5
- Sores in your mouth that don't heal 5
- Avoid invasive dental procedures (like tooth extractions or implants) while on Prolia when possible 5
- Maintain excellent oral hygiene with regular brushing and flossing 5
Unusual Thigh, Hip, or Groin Pain
- New or unusual pain in your thigh, hip, or groin could be a warning sign of an atypical fracture 5
- Report any new pain in these areas to your doctor right away 5
Signs of Infection
- Fever or chills 5
- Severe abdominal pain 5
- Painful urination or urinary symptoms 5
- Skin infections, redness, or warmth 5
Skin Reactions
Critical Warning: Never Stop Prolia Suddenly
This is the most important thing to understand about Prolia: you cannot simply stop taking it without a plan. 5, 7
- Unlike other osteoporosis medications, Prolia does not stay in your bones after you stop 5, 7
- If you stop Prolia without transitioning to another medication, you are at high risk for multiple spine fractures within 7-19 months 5, 7
- These "rebound" fractures can be severe and involve multiple vertebrae at once 5, 7
- If you need to stop Prolia for any reason, your doctor must immediately start you on another bone medication (usually an IV infusion of zoledronic acid) within 6-7 months of your last Prolia dose 5
- Do not apply the concept of a "drug holiday" to Prolia—this medication requires continuous treatment or immediate transition to another therapy 5
How Long Will You Take Prolia?
- Studies show Prolia is safe and effective for up to 10 years of continuous treatment 5, 3
- Your bone density continues to improve the longer you take it 3
- Most patients with high fracture risk should continue Prolia indefinitely unless there is a specific reason to stop 5
- Your doctor will monitor you with bone density scans every 1-2 years 5
Dental Care While on Prolia
- See your dentist for regular checkups at least once a year 5
- Tell every dentist and oral surgeon that you are taking Prolia 5
- Maintain excellent oral hygiene with daily brushing and flossing 5
- If you need dental surgery, discuss timing with both your dentist and the doctor prescribing Prolia 5
Monitoring and Follow-Up
Your healthcare team will monitor you regularly: 5
- Blood tests to check calcium levels, especially if you have kidney problems 5, 1
- Bone density scans every 1-2 years to track your progress 5
- Regular assessment for any signs of infection, jaw problems, or unusual bone pain 5
- Annual dental examinations 5
When to Call Your Doctor
Contact your healthcare provider immediately if you experience: 5, 1
- Symptoms of low calcium (muscle spasms, numbness, tingling) 1
- Jaw pain, loose teeth, or mouth sores that don't heal 5
- New thigh, hip, or groin pain 5
- Signs of infection (fever, severe abdominal pain, painful urination) 5
- Severe skin reactions 5
- Severe bone, joint, or muscle pain that is new or worsening 5
Special Considerations
- If you have kidney disease: You are at higher risk for low calcium and will need closer monitoring with more frequent blood tests 1
- If you are planning pregnancy: Prolia can harm an unborn baby; discuss birth control and family planning with your doctor 1
- Prolia does not require dose adjustment based on age, making it suitable for older adults 5
Advantages of Prolia
- Only requires an injection every 6 months (not daily or weekly pills) 1, 8
- No need to stay upright or avoid eating/drinking like with oral bisphosphonates 4
- Safe for patients with kidney impairment (unlike some other osteoporosis medications) 4, 5
- Effective for patients who cannot tolerate or have failed other osteoporosis treatments 1
Remember Your Daily Supplements
You must take calcium and vitamin D supplements every single day while on Prolia. 1
