The US black box warns of the risk of serious injury from certain complex sleep behaviors of insomnia drugs

On April 30, 2019, the US Food and Drug Administration (FDA) released a report that certain common treatments for insomnia are due to complex sleep behaviors (including sleepwalking, sleep driving, and other activities that are not fully awake). A rare but serious injury or even death has occurred. These behaviors appear to be more common in eszopiclone, zaleplon, and zolpidem than other prescription drugs used to treat insomnia. Therefore, the FDA requires black box warnings in these drug instructions and patient medication guidelines, as well as requiring patients who have previously experienced abnormal sleep behavior with eszopiclone, zaleplon, and zolpidem as taboos. .

Eszopiclone, zaleplon, and zolpidem are sedative and hypnotic drugs used to treat adult sleep disorders and have been approved for many years. Severe injuries and deaths caused by complex sleep behavior occur in patients with or without such a history of behavior, whether using the lowest recommended dose or a single dose, with or without alcohol or other central nervous system inhibitors (eg sedatives, opioids) Abnormal sleep behavior may occur with these drugs, such as drugs, and anti-anxiety drugs.

For medical staff information:

Patients with complex sleep behavior after taking eszopiclone, zaleplon, and zolpidem should avoid these drugs; if patients have complicated sleep behavior, they should stop using these drugs because of these drugs. Although rare, it has caused serious injury or death.
For patient information:

If the patient is not fully awake after taking the medicine, or if you do not remember the activities you have done, you may have complicated sleep behavior. Stop using the medicine for insomnia and seek medical advice immediately.

Over the past 26 years, the FDA has reported 66 cases of drugs that cause complex sleep behaviors, which are only from the FDA’s Adverse Event Reporting System (FEARS) or medical literature, so there may be more undiscovered cases. 66 cases included accidental overdose, falls, burns, drowning, exposure to limb function at extremely low temperatures, carbon monoxide poisoning, drowning, hypothermia, motor vehicle collisions, and self-injury (eg gunshot wounds and apparent suicide) attempt). Patients usually do not remember these events. The underlying mechanisms by which these insomnia drugs cause complex sleep behavior are currently unclear.

The FDA also reminded the public that all drugs used to treat insomnia will affect the next morning driving and other activities that require vigilance. Drowsiness has been listed as a common side effect on drug labels for all insomnia drugs. The FDA warns patients that they will still feel drowsy the next day after taking these products. Patients who take insomnia medications may experience a decrease in mental alertness even if they feel completely awake the next morning after use.
