The warning (http://tinyurl.com/b7kc4r2) focuses on the popular sleep medication zolpidem, which data reviewed by the FDA suggest may persist at levels high enough to impair driving 8 hours or more after dosing. To mitigate such risk, the FDA is recommending physicians prescribe the lowest dose necessary and is requiring manufacturers of the drugs to lower the recommended doses that appear on the drug's label. Women and individuals who have taken extended-release formulations of zolpidem may be at particularly increased risk of impaired alertness the morning after taking these medications, noted the agency.
