Some sleep drugs do more than make you sleep

The United States Food and Drug Administration1 has ordered companies to place strong new warnings on thirteen drugs that treat sleep disorders. It also ordered the makers of the sleeping pills to provide information for patients explaining how to safely use the drugs.
Last Wednesday, the FDA announced that some of these drugs can have unexpected and dangerous effects. These include the risk of life-threatening allergic reactions.
