Patients on hypnotics at greater risk of road traffic accidents
Patients prescribed benzodiazepine-like hypnotics are at an increased risk of being involved in road traffic accidents, a Norwegian population study has found.
Researchers followed up 3.1 million Norwegians aged between 18 and 69 from January 2004 until September 2006, and pooled data with information on prescriptions from three Norwegian registries.
The standardised incidence of accidents during exposure was 2.3 for zopliclone and zolpidem and 2.7 for nitrazepam, compared with unexposed individuals.
