Newly prescribed sleeping pills increase risk of hip fracture

Older people newly prescribed sleeping pills like benzodiazepines and ‘Z-drugs’ have over double the odds of a hip fracture in the first two weeks compared with non-users, according to a new study by researchers at Cardiff University and King’s College London.

Ben Carter, of Cardiff University’s School of Medicine, explains: “While Z-drugs are fast becoming the doctor’s hypnotic prescription of choice, there is no evidence that they are a safer alternative to benzodiazepines in relation to hip fracture risk.

He said: “Our study shows that both appear to significantly increase the risk of hip fracture when newly prescribed by doctors.”

The study of people aged over 65 found that new users of these hypnotic medicines experienced nearly two-and-a-half times the fracture rate, when compared with people not taking hypnotics. An estimated 53 per cent increase in fracture risk was identified in medium-term users (15 to 30 days), and a 20 per cent increased risk of hip fracture in long-term users (more than 30 days).

Dr Carter added: “Careful consideration of the immediate increased risk of hip fracture should inform the clinical decision-making process. Clinically effective measures like strength training to improve frailty, removal of hazards at home, visual correction and a medication review are also needed to mitigate the risk of hip fractures, particularly in the first few days of use.”

The research supports previous studies linking use of hypnotics by older people with an increased risk of accidents, dependence, cognitive decline and hip fracture. The drugs are also thought to cause drowsiness, delayed reaction times and impaired balance.
