Do osteoporosis drugs cause fractures?

Certain types of osteoporosis drugs have been associated with an increased risk of two rare but serious problems — osteonecrosis of the jaw and an unusual type of fracture in the upper thigh bone (femur).

Why do bisphosphonates cause fractures?

Long-term bisphosphonate therapy can change bones at the microscopic level to make them more susceptible to the rare catastrophic transverse breaks known as atypical femoral fractures (AFFs), scientists said.

Can Fosamax cause fractures?

Fosamax Bone Fractures

Though Fosamax is given to prevent bone loss and fractures, in some cases, Fosamax side effects may contribute to weakened and broken bones. Fosamax-related fractures may occur in the femur, which is one of the body’s strongest bones or may result from damage to the jawbone.

How much do bisphosphonates reduce fracture risk?

3. Efficacy of bisphosphonate for osteoporotic fracture risk reduction. In the random effects model for all studies, the use of bisphosphonate was associated with a decreased risk of osteoporotic fracture (OR 0.62; 95% CI 0.54 to 0.71 P<0.001).

Do bisphosphonates make bones more brittle?

What are the symptoms of osteonecrosis of the jaw?

What are the symptoms of ONJ?

  • pain or swelling in the mouth.
  • non-healing of a tooth socket after removal of teeth.

What organs are affected by osteoporosis?

Osteoporotic bone breaks are most likely to occur in the hip, spine or wrist, but other bones can break too. In addition to causing permanent pain, osteoporosis causes some patients to lose height. When osteoporosis affects vertebrae, or the bones of the spine, it often leads to a stooped or hunched posture.

What are the two medications that may cause osteoporosis after long term use?

The medications most commonly associated with osteoporosis include phenytoin, phenobarbital, carbamazepine, and primidone. These antiepileptic drugs (AEDs) are all potent inducers of CYP-450 isoenzymes.

Does Fosamax affect teeth?

The complications with Fosamax in relation to dental are called “Bisphosphonate-related osteonecrosis of the jaw” (BRONJ). For example, when you have an extraction done or experience trauma to the jawbone the bones mechanisms for repairing itself are impaired and can lead to necrosis in the area.

Why is Fosamax bad for you?

There are concerns about the long-term safety of bisphosphonates (such as Fosamax) as long-term use has been associated with atypical femur fractures, osteonecrosis of the jaw, and esophageal cancer. Fracture risk reduction may also persist for years after treatment has stopped.
