The FDA has labeled Ambien and other sleep medications with a “black box” warning, which is the strongest listed by the agency.
The behaviors are associated with eszopiclone (Lunesta), zaleplon (Sonata), and zolpidem (Ambien, Ambien CR, Edluar, Intermezzo, Zolpimist) than other prescription medicines used for sleep.
“We are also requiring a contraindication, our strongest warning, to avoid use in patients who have previously experienced an episode of complex sleep behavior with eszopiclone, zaleplon, and zolpidem,” the health agency wrote.
The FDA looked into data spanning 26 years, finding 66 examines of complex sleep behaviors associated with the medications.
Some consumers performed actions that led to lost limbs, extreme cold, and hypothermia. Meanwhile, the FDA said there were instances of drowning, car crashes, carbon-monoxide poisoning, and suicide attempts.
The agency stated that some patients who took the medications don’t remember the incidents that led to their injuries.
“These incidents can occur after the first dose of these sleep medicines or after a longer period of treatment, and can occur in patients without any history of these behaviors and even at the lowest recommended doses,” Sharpless stated.
He said it’s not clear how the medications trigger complex sleep behaviors that led to harm.
Sharpless said officials noted that millions of Americans have insomnia and rely on such medications “to help them sleep better at night,” adding that “these incidents are rare” but “they are serious and it’s important that patients and health care professionals are aware of the risk.”
He noted that the move on April 30 is “an important step in our ongoing effort to call more attention to these critical safety issues and serves as an example of our ongoing commitment to ensuring that patients and health care professionals have the information they need to make informed treatment decisions.”
She noted that it’s not clear why they experience the symptoms.
“It may be that some people are genetically prone anyway to these kinds of disorders and the medication can become an additional trigger,” Foldvary-Schaefer said.
Recommended dosage “is 5 mg for women and either 5 or 10 mg for men, taken only once per night immediately before bedtime with at least 7-8 hours remaining before the planned time of awakening. If the 5 mg dose is not effective, the dose can be increased to 10 mg,” says RXList.
