WASHINGTON (CBSNewYork/AP) — The Food and Drug Administration is requiring makers of Ambien and similar sleeping pills to lower the dosage of their drugs, based on studies suggesting patients face a higher risk of injury due to morning drowsiness.
The agency said Thursday that new research shows that the drugs remain in the bloodstream at levels high enough to interfere with morning driving, which increases therisk of car accidents.
Regulators are ordering drug manufacturers to cut the dose of the medications in half for women, who process the drug more slowly. Doses will be lowered from 10 milligrams to 5 milligrams for regular products, and 12.5 milligrams to 6.25 milligrams for extended-release formulations.
The FDA is recommending that manufacturers apply these lower doses to men as well, though it is not making them a requirement.
“Some of my patients report that they wake up in the middle of the night eating, walking, talking and things like that with Ambien,” Dr. Vicki Seelall told CBS 2’s Dana Tyler.
The new doses apply to all insomnia treatments containing the drug zolpidem, which is sold under brands including Ambien, Edluar and Zolpimist.
FDA officials say doctors should aim to prescribe the lowest dose possible that will successfully treat insomnia.
“Patients who must drive in the morning or perform some other activity requiring full alertness should talk to their health care professional about whether their sleep medicine is appropriate,” said Dr. Ellis Unger, a director in FDA’s Office of Drug Evaluation.
Unger said in a statement that the FDA has received a number of reports of car accidents connected to zolpidem over the years. However, the agency did not have enough information to tell how much of a role the drug played in the incidents.
Patrick Kennedy, a former Rhode Island congressman, said he was asleep when he crashed his car in 2006. He blamed the crash on Ambien.
The agency decided to take action after recent driving simulation studies showed that, in some patients, drug levels remained high enough to cause difficulty driving.
For now, patients should continue taking their currently prescribed dose until they can talk to their doctor about the best way to proceed.
Ambien is sold by Sanofi, Edluar by Meda Pharmaceuticals Inc. and Zolpimist by NovaDel Pharma Inc.
Also Thursday, Mayor Michael Bloomberg’s Task Force on Prescription Painkiller Abuse issued new rules to prevent prescription drug abuse in the city’s 11 public emergency rooms.
Under the new guidelines, doctors can only prescribe up to a three-day supply of opioids to ER patients in the city’s public hospitals. Emergency departments will also no longer prescribe long-acting opioid painkillers.
