This finding makes total sense when you realize that Ambien, a short-acting nonbenzodiazopine hypnotic, can cause ataxia, poor motor control, difficulty maintaining balance, dizziness, and sleepwalking. The last thing a person with fragile bones needs to be doing is dizzily walking around in their sleep . The kicker here is that a 2012 NIH study published in the British Medical Journal concluded that much of Zolpidem’s effectiveness is psychological…in other words, a placebo effect. The study concluded that greater caution should be used when prescribing Ambien to individuals at risk for fracture and that “increased attention should be directed at psychological intervention of insomnia”.
