Sleep meds evidence for shift workers weak

The review included 15 trials involving 718 people, and most of the data was from small, low quality trials, the authors said.

In nine trials, melatonin helped shift workers sleep for around 24 minutes longer during the night or day, compared to placebo. However, it did not help them get to sleep any quicker.

Only one trial included data on the hypnotic drug zopiclone, which showed it was no more effective than placebo for helping shift workers sleep during the day.

The remaining trials focused on caffeine, and modafinil and armodafinil (not available in Australia), which are prescribed for sleepiness
