People taking common sleep drug may not realize they're too impaired to drive, study finds

A popular antipsychotic medication was found to reduce obstructive sleep apnea (OSA) – but it also led to impaired driving the next morning.

That’s according to a small randomized controlled trial published in the Annals of the American Thoracic Society.

Researchers from Flinders University in Adelaide, Australia, conducted the study in 15 adults with OSA who also had difficulty maintaining sleep. Each participant underwent two overnight sleep studies approximately one week apart, according to a press release.
