(NEW YORK) -- The Food and Drug Administration sent out a warning Thursday for the popular sleep aid Lunesta, recommending only half the current dosage following concerns over its effects. The agency now requires the drug's manufacturer to change the label and lower the recommended starting dose. Data shows that levels of the drug eszopiclone may be high enough to impair activities the morning after, including driving.
The decrease pushes back the dosage from 2 milligrams to 1 mg for both men and women. Higher doses can be taken if necessary, the FDA says, but they're more likely to impair next-day activities that require full alertness.
More than seven hours after taking a 3 mg dose, many people can suffer problems with memory and coordination, according to the FDA's Center for Drug Evaluation and Research director, Ellis Unger. At more than 11 hours, some are still unknowingly affected by the sleeping pill.
In similar action in 2013, the agency announced a dose reduction for sleep drugs containing the active ingredient zolpidem, such as Ambien, due to the risk of next-morning impairment.
