Opioids are powerful narcotic pain medications that include morphine, oxycodone (Oxycontin and other brands) and hydrocodone (Vicodin and others).

The drugs work well against severe pain in the short term, but their longer-term effectiveness for chronic pain is less clear. Moreover, with longer use comes the risk of addiction, in addition to side effects such as nausea, constipation, dizziness and sedation.

That dizziness and sedation can also set opioid users up for falls, which, in older people especially, may result in serious fractures.

Researchers found that among more than 2,300 older adults with chronic pain, the risk of suffering a bone fracture was higher when patients were using an opioid for a prolonged period than when they were opioid- free.
