The U.S. FDA has issued an advisory recommending a lower dose for products containing the hypnotic zolpidem, such as Ambien, Ambien CR, Edluar, and Zolpimist. In Canada, zolpidem is sold under the trade name Sublinox. Dosing for Intermezzo, a zolpidem formulation for middle-of-the-night awakening, is unaffected.
