SILVER SPRING, Md. — The Food and Drug Administration is ordering the makers of several sleep drugs to lower the recommended dosage due to the risk that they can impair patients the morning after, the agency said Thursday.
The FDA announced that it was requiring the manufacturers of drugs containing the active ingredient zolpidem to lower the current recommended dosage in light of new data showing that the morning after use, the drug can remain in the blood in sufficient quantities to impair activities that require alertness, such as driving.
