Medications That Can Be Bad for Your Bones
If you take a moment to read the tiny contents of the package insert that comes with your prescription drugs, you will see in the section on side effects that there are many that can harm your bones. Some drugs can cause bone loss and some may increase the chance of breaking a bone. If you have certain diseases, you may not have a choice but to take one of these medications. If you do, it is extra important to take steps to protect your bones.
The most common medications that can harm your bones include:
- High doses of cortisone-like pills, such as prednisone
- Drugs that can reduce your estrogen or androgen levels
- Certain diabetes medications
- Certain stomach medications such as antacids that contain aluminum or proton pump inhibitors
- Certain antidepressants, particularly selective serotonin receptor uptake inhibitors (SSRI’s)
- Some blood thinners and anticoagulants
- Loop diuretics
- Some anti-convulsive medications
- Know your bone density which can help inform you about your risk of breaking a bone and may be useful to monitor any potential bone loss.
- If you are at high risk for breaking a bone, your health care provider may suggest an osteoporosis medication to reduce the harmful effects on your skeleton.
- Take as low a dose as possible, for as short a time as possible – but talk with your healthcare provider before you make any changes.
- Make sure that you get 3-4 servings of a calcium-rich food every day. If you cannot eat dairy or calcium-fortified food, you may need a calcium supplement.
- Be sure that you have an optimal vitamin D level (≥ 30 ng/mL or ≥74.9 nmol/L). People with breast cancer and prostate cancer may need higher blood levels of vitamin D.
- Practice great posture and use good body mechanics to prevent spine fractures.
- Strengthen your legs and do balance exercises to prevent falls and fractures.
- Remove trip hazards from your home.
If you are taking high doses of steroid-like pills such as prednisone
Steroids are often used to help reduce inflammation and pain for people who have rheumatoid arthritis, lupus, Crohn’s disease and asthma. Because these diseases are chronic, people often take them for long periods of time. Daily doses of over 5 mg are the most harmful to the bones.
The impact of systemic (oral or IV/IM) steroids on the skeleton happens rapidly, often within three months of starting the drug. Systemic steroids affect the bone remodeling process by decreasing the activity of the bone-building cells (osteoblasts) and increasing the activity of the cells that break down bone (osteoclasts). The combination of these actions causes bone loss quickly.
To lessen the harm to the bones from steroid medications: Stay on as low a dose of the steroid as possible to manage inflammation and pain – try for 5 milligrams or less per day.
List of common steroid medications that affect the skeleton
- Prednisone: Deltasone®, Rayos®, Prednisone Intensol®, etc.
- Prednisolone: Omnipred®, Pediapred®, Pred Mild®, etc.
- Methyprednisolone: Medrol®, Solu-Medrol®, Depo-Medrol®, ReadySharp®,
P-Care D40®, P-Care D80®, etc.
- Dexamethasone: Decadron®, Ozurdex®, DexPak 6 Day®, DexPak 13 Day®, Dexamethasone Intensol®, DexPak 10 day®, Maxidex®, LoCort®, etc.
- Cortisone: Cortison, Cortisone, Cortisone Acetate, Cortone, Cortistab, Cortisyl, Adreson, etc.
- Triamcinolone: Aristocort®, Aristocirt Forte®, Aristospan®, Clinacort®, Kenalog-10®, Kenalog-40®, Triamcot®, Triam-Forte®, Triesense®, etc
If you are taking drugs that can reduce your estrogen or androgen level
Estrogens and androgens, such as testosterone, are hormones that can worsen some medical conditions such as breast cancer, uterine cancer, prostate cancer, endometriosis and uterine fibroids. The medications used to treat these conditions often reduce the level of estrogen or androgens in your body. This reduction in hormones causes an increase in the activity of the osteoclasts, followed by an increase in bone loss.
List of common hormone blockers that affect the skeleton
- Aromatase inhibitors (Arimidex®, anastrozole, Aromasin®, exemestane, Femara®, letrazole, etc.)
- Androgen/estrogen deprivation therapy/gonadotrophin agonists/antagonists (Lupron®, Lupron Depot®, leuprorelin, Eligard®, leuprolide, Zoladex®, goserelin, Suprefact®, buserelin, Eulexin®, flutaminde, Trelstar®, triptorelin, Vantas®, histrelin, Firmagon®, degarelix, long-term treatment with Cetrotide®, cetrorelix or Antogon®, ganirelix, etc.)
- Depomedroxyprogesterone acetate injections. (Depo-Provera®, Depo-Ralovera®, etc.)
If you are taking a drug for diabetes
Some medications used for people with diabetes increase the risk of fractures. TZD drugs cause an increase in the number of fat cells in the bone marrow at the expense of bone-forming osteoblasts. SGLT-2 inhibitors may reduce the bone density at the hip and increase fracture risk, although some data are conflicting. Both type 1 and type 2 diabetes are associated with increased risk of breaking a bone, although bone density is usually lower than average in people with type 1 diabetes and higher than average in people with type 2 diabetes. You should talk with your diabetes doctor before stopping or changing any of your medications.
To lessen the harm to the bones from diabetes medications:
- If you are at increased risk of breaking a bone, try to avoid the use of a TZD.
- If you are at increased risk of falls, try to avoid the use of a SGLT-2 inhibitor
List of common diabetes medications that affect the skeleton
- Thiazolidinediones or TZDs, (Actos® or pioglitazone, Avandia® or rosiglitazone)
- SGLT-2 Inhibitors (Invokana® or canagliflozin, Forxiga® or dapagliflozin, Jardiance® or empagliflozin, etc.)
If you are taking an antacid
People who have acid reflux, stress gastritis, or peptic ulcers may take a variety of antacids, both prescription and over the counter, that reduce acid and heartburn or abdominal pain. However, the long-term, daily use of aluminum-containing antacids or proton pump inhibitors (PPI) may affect the absorption of calcium and appears to increase the risk of fracture.
To lessen the harm to the bones from antacids:
- Consider an H2-blocker such as Zantac® (ranitidine) 75 to 150 mg twice daily instead of a PPI.
- Consider changes to your diet to reduce acid production.
List of common acid-reducing medications that affect the skeleton
- Antacids with aluminum (Maalox®, Mylanta®, Riopan®)
- Proton Pump Inhibitors (Prilosec® or omeprazole, Nexium® or esomeprazole, Prevacid® or lansoprazole, Protonix or pantoprozole, Aciphex® or rabeprazole, Dexilent or dexlansoprazole)
If you are taking antidepressants
A common medication for depression is a selective serotonin receptor uptake inhibitor or SSRI. This particular antidepressant medication increases fracture risk and bone loss in older women and is associated with lower bone density in children and men.
To lessen the harm to the bones from antidepressants:
- Consider a SNRI (serotonin and norepinephrine reuptake inhibitor) instead of an SSRI
- Avoid SSRIs if you have other factors that increase your risk of breaking a bone

If you are taking blood thinners and anticoagulants
Patients who are at risk for stroke or blood clots are often prescribed a blood thinner or a medication that reduces the chance of blood clots. These medications prevent the absorption of calcium and affect the bone-building cells leading to bone loss and increased risk of breaking a bone. WarfarinÒ, in particular, may also affect vitamin K metabolism. Newer anticoagulants that don’t inhibit vitamin K such as Pradaxa® (dabigratan), Xarelto® (rivaroxaban), Eliquis® (apixaben) and Arixta appear to be safer for the skeleton than Warfarin or heparin.

If you are taking loop diuretics
People with high blood pressure, congestive heart disease, kidney disease and liver disease are often prescribed loop diuretics to reduce swelling, water retention or edema. The loop diuretics such as furosemide (LasixÒ) increase the production of urine by the kidneys and removes calcium, potassium and magnesium salts from the body. The loss of calcium in the urine increases bone loss and fracture risk. In contrast, thiazide diuretics cause the kidney to hold on to calcium, and tend to increase bone density. There is also research that connects the use of some loop diuretics with falls and increases the risk of spine fractures.
To lessen the harm to the bones from loop diuretics:
- Consider changing to a thiazide diuretic.
List of common loop diuretics that affect the skeleton
- Lasix® (furosemide), Edecrin® (ethacrynic acid), Bumex® (bumetanide) and Demadex® (torsemide), Aldactone, Dyazide, Diamox
If you are taking anti-convulsive medications
Anti-convulsive medications are used for people who have seizures or epilepsy. Some of the medications increase vitamin D metabolism in the liver and lower vitamin D levels. Since vitamin D is necessary for calcium absorption, the use of these medications increases bone loss and fracture risk.
To lessen the harm to the bones from an anti-convulsive medication:
- Take enough vitamin D to raise your blood level to 30-50 ng/mL
Additional steps your health care provider may take when you are taking an anti-convulsive medication.
