Is This Information Right for Me?
Yes, this information is right for you if:
- Your doctor* has said you have low bone density. People with low bone density have one of two conditions:
- Osteopenia (pronounced AH-stee-oh-peen-ee-ya): mild low bone density
- Osteoporosis (pronounced AH-stee-oh-pohr-oh-sis): severe low bone density
- Your doctor has said you may have a higher risk of breaking a bone because of your low bone density.
- You have broken a bone by falling while standing.
- Your doctor has suggested medicines to lower your risk of breaking a bone.
* In this summary, the term “doctor” refers to the health care professionals who may take care of you, including your physician, nurse practitioner, or physician assistant.
No, this information is not right for you if:
- Your doctor has not said you have low bone density or that you need medicines to lower your risk for broken bones.
- You are under 18. This research was done on adults.
What does this summary cover?
This summary explains how low bone density can increase the risk of breaking a bone and what research has found about different treatments to lower the risk. It can help you talk with your doctor about which treatment might be right for you.
Where does the information in this summary come from?
Researchers funded by the Agency for Healthcare Research and Quality (AHRQ), a Federal Government research agency, reviewed 567 studies published between January 2005 and March 2011 on low bone density treatments. The report was reviewed by clinicians, researchers, experts, and the public. You can read the report at www.effectivehealthcare.ahrq.gov/lbd.cfm.
Understanding Your Condition
What is low bone density?
Low bone density is a condition where the tissue inside your bones begins to thin, or becomes less dense. There are two forms of this condition: osteopenia (mild low bone density) and osteoporosis (severe low bone density).
What causes low bone density?
Your bones are made of living tissue that never stops growing. The layers of tissue in your bones constantly rebuild. Your body breaks down and removes old bone tissue and forms new bone tissue to replace it.
When you are young, new bone replaces old bone quickly. This makes your bones solid and strong. As you get older, your body loses bone tissue faster than it can be replaced. This makes your bones less solid and weaker.
Most people’s bones get weaker as they get older. Whether or not a person has osteopenia or osteoporosis depends on how much of their bone density is lost.
How common is low bone density?
- About 52 million people in the United States are affected by osteoporosis or low bone density.
- Both men and women can have low bone density.
- Osteoporosis is more common in women, especially women who have gone through menopause. About one in five women in the United States who are over the age of 50 have osteoporosis.
How do I know my risk for breaking a bone?
Your doctor may have used a bone scan or spoken to you about the World Health Organization Fracture Risk Assessment Tool (FRAX®) calculator to estimate your risk of bone fracture.
Around one in two women over the age of 50 and one in five men will break a bone because of osteoporosis during their lifetime.
Who is most likely to break a bone?
Women, especially those who have gone through menopause or younger women whose ovaries no longer work, have a higher risk for breaking a bone.
Others with a higher risk for breaking a bone include people with:
- Increasing age.
- A history of broken bones from falling.
- Caucasian heritage.
- Rheumatoid arthritis.
- History of smoking.
- Alcohol use.
- Low levels of vitamin D.
- Not enough calcium in their diet.
- A higher risk for falling due to poor balance or other causes.
- Conditions that require medicines like Prednisone® or other steroids, blood thinners, anti-seizure drugs, or breast or prostate cancer drugs.
Why are broken bones dangerous?
Broken bones can cause serious health problems:
- The most common bones that break are the hip, wrist, and spine (backbone).
- Broken bones can cause ongoing pain and make it hard to do daily activities.
- The bones in your spine can crunch together and cause pain. This could cause you to lose an inch or more of height.
- While recovering from a broken bone—especially the hip—you may need constant care and may have to stay in a nursing home.
- If you break your hip, you will probably need surgery to fix it. Surgery increases your risk for other health problems.
- Once you break a bone, you may be more likely to break other bones, which could lead to more health problems.
Understanding Your Options
What treatments can help lower the risk of breaking a bone?
For people with low bone density, there are treatments that can help strengthen your bones and lower your risk of breaking a bone. Your doctor may suggest one or more of the following treatments:
What medicines are available?
Medicines that help reduce the risk of breaking a bone either help slow the breakdown of old bone or help build new bone more quickly.
- Most research has been done to see how well these medicines work for women with osteoporosis who have already gone through menopause. Not as many studies have been done to see if these medicines work for men or for women who have not gone through menopause.
- Some of these medicines may also be taken by people with osteopenia.
- There is not enough research to exactly know how much the medicines will lower the risk of breaking a bone.
- Even if your bone density does not change while you are taking medicine, that does not mean the medicine is not working to protect you from breaking a bone.
Medicines and the Bones They Protect
For women with osteoporosis who have gone through menopause, researchers found that the following medicines do or do not lower the risk of breaking the bones listed.
| = does reduce risk; = does NOT reduce risk; — = unknown.
* These medicines appear to lower the risk of breaking a wrist bone, but there is not enough research to know for sure.
** In women who have gone through menopause but do NOT have osteoporosis, MHT lowers the risk of breaking the spine, hip, or other bones.
|Risedronate (Actonel® or Atelvia®)||*|
|Zoledronic acid (Reclast®)||—|
|Menopausal Hormone Therapy (MHT)**|
How long will the medicine protect my bones?
There is not enough research to say how long most medicines might protect you from breaking a bone, or how long you may need to take a medicine. There is some evidence that taking alendronate (Fosamax®) for more than 5 years may protect your spine from breaking. Some women may experience protection for bones other than their spine after taking this medicine for 5 years, while other women will not. Only women who still have osteoporosis or bone breaks in their spine after the first 5 years of treatment may gain protection for bones other than their spine by taking medicine for 5 more years.
Bisphosphonates (pronounced biss-FOSS-fuh-nates) are a group of medicines that slow the breakdown of bones.
|Drug Name||Brand Name||How It Is Taken|
- For alendronate (Fosamax®), ibandronate (Boniva®), and risedronate (Actonel®), you must take the pill on an empty stomach with a full glass of water. You must also be standing up, and you cannot lie down for at least 30 minutes after taking any of these medicines.
- Unlike other bisphosphonate pills, Atelvia® must be taken with food, and is usually taken right after breakfast.
- For women with osteoporosis who have gone through menopause:
- Alendronate (Fosamax®) lowers the risk of breaking the spine, hip, or other bones. This medicine may also protect your wrist, but there is not enough research to say for certain.
- Ibandronate (Boniva®) lowers the risk of breaking the spine.
- Risedronate (Actonel® or Atelvia®) lowers the risk of breaking the spine, hip, or other bones. This medicine may also protect your wrist, but there is not enough research to say for certain.
- Zoledronic acid (Reclast®) lowers the risk of breaking the spine, hip, or other bones.
- If you do not follow your doctor’s instructions for taking bisphosphonates, your risk of breaking a bone increases.
- Some medicines are made for you to take once a week (instead of once a day). Others are taken only once a month or once a year.
- Many people find it easier to take these medicines once a week.
- There is not enough research to know if people find it easier to take medicines once a month.
- Side effects might be different for once-a-week and once-a-month medicines.
- There is not enough research to know if any one bisphosphonate works better than any other.
- Denosumab is a medicine that slows the breakdown of bones.
- This medicine is for women after menopause, for men, and for women undergoing treatment for some types of cancer.
- It is given as a shot at your doctor’s office every 6 months.
What does research say about denosumab (Prolia®)?
Researchers found that denosumab lowers the risk of breaking the spine, hip, or other bones in women with osteoporosis who have gone through menopause.
- Raloxifene is another medicine that slows the breakdown of bones.
- This medicine is only for women after menopause.
- Raloxifene is not a hormone, but it keeps bone from breaking down like the natural female hormone estrogen.
- Raloxifene is a pill that you usually take every day with or without food. You have to take this pill at about the same time every day.
What does research say about raloxifene (Evista®)?
- Raloxifene lowers the risk of breaking the spine in women with osteoporosis who have gone through menopause.
- Raloxifene does NOT lower the risk of breaking the hip, wrist, or other bones in women with osteoporosis who have gone through menopause.
- Teriparatide is a medicine that acts like a natural hormone. It helps your body form new bone.
- This medicine is for women after menopause and for men.
- It is a shot taken every day that comes in a “pen”—a device you use to inject the medicine into your belly or thigh.
What does research say about teriparatide (Forteo®)?
Researchers found that teriparatide lowers the risk of breaking the spine and other bones in women with osteoporosis who have gone through menopause.
Menopausal Hormone Therapy (MHT)
- MHT is a therapy where women take hormone supplements. Doctors use estrogen or estrogen with progestin for this therapy.
- This treatment is only for women who have gone through menopause.
- MHT can have serious side effects. It can increase your risk of stroke, heart disease, and breast cancer.
- Because of the risk for serious side effects, many health professionals no longer recommend taking estrogen with progestin to prevent osteoporosis.
What does research say about MHT?
- MHT does not lower the risk of breaking a bone in women with osteoporosis who have gone through menopause.
- In women who have gone through menopause but do NOT have osteoporosis, MHT helps prevent the spine, hip, and other bones from breaking.
What are the possible side effects of these medicines?
|Medicines||Possible Side Effects*||Additional Information|
|* This list is from both research studies and the U.S. Food and Drug Administration.|

|Increased risk of bone cancer||This side effect happened at doses that were higher than what people usually take.|
Can nutritional supplements help keep my bones healthy?
Your doctor may recommend you take calcium and vitamin D alone or with your prescription medicines to help strengthen your bones and lower your risk of developing osteoporosis. Researchers are not sure if taking calcium or vitamin D without other treatment reduces the risk of breaking a bone for people with osteoporosis.
Your body needs calcium to build bones, and vitamin D helps your body use calcium. The amount of calcium and vitamin D you need each day depends on your age.
It is important to make sure your diet is high in calcium and vitamin D. You can get calcium and vitamin D from many foods. Your doctor may recommend you buy pills (prescription or over-the-counter) that contain calcium and vitamin D. Talk with your doctor about how much calcium and vitamin D is right for you.
Sources of calcium include:
- Dairy foods like milk, cheese, and yogurt.
- Dark green leafy vegetables like broccoli and kale.
- Bread, pasta, cereal, and rice contain low amounts of calcium.
- Foods that are “fortified” with calcium (contain added calcium), like many fruit juices, tofu, and cereals.
Sources of vitamin D include:
- Fatty fish like salmon, tuna, and mackerel.
- Green leafy vegetables.
- Beef liver and egg yolks provide a small amount of vitamin D.
- Foods fortified with vitamin D, like milk, cereal, some fruit juices, and yogurt.
- Nausea, vomiting, poor appetite, constipation, weakness, or weight loss
- Confusion, becoming disoriented, or an irregular heartbeat
Can exercise help?
Your doctor may also recommend exercises to help strengthen your bones, improve your balance, and reduce your chance of falling.
- “Weight-bearing” exercises use extra weight and gravity to make bones stronger.
- Weight-bearing exercises include walking, lifting weights, and climbing stairs.
- Some exercises may be too hard on your bones and can increase your risk of breaking a bone. For example, activities like golf require you to twist your body in ways that might be dangerous.
- Talk with your doctor about what exercises are best for you.
Making a Decision
What should I think about when deciding?
- Helps calculate your risk of breaking a bone.
- Provides detailed information about medicines used to prevent bone fractures.
- Allows you to print information and questions to take to your doctor.
Only you and your doctor can decide whether any medicine’s ability to help your condition is worth the risk of a serious side effect. Each person responds differently to different medicines. Your doctor may try several medicines before finding the right one.
There are several things to consider when deciding which treatment might be best for you:
- If you have osteopenia (mild low bone density), whether you need to start medicines now or can wait and see if your condition gets worse.
- What your bone density test says is your risk for breaking a bone.
- The benefits and side effects of each treatment.
- Ways your doctor can help you notice any side effects so they can be treated or the medicine can be changed.
- Which medicine best fits your daily life and routine.
- The out-of-pocket costs of each treatment option, and whether medicines come in generic form.
What are the costs of treatment?
The wholesale prices of prescription osteoporosis medicines are listed below. Wholesale prices are the prices paid by pharmacies. These prices are given here so you can compare the cost of different medicines.
