Common sleeping tablets include Ambien, Intermezzo, Lunesta, Rozerem and Sonata, according to WebMD. Other sleeping tablets include Silenor, Halcion, Restoril, Xanax and Trazodone. Most are effective when used in conjunction with good sleep habits.
Sleeping tablets are used to treat insomnia and generally work by focusing on the sleep-wake cycle, depressing the central nervous system and blocking histamine receptors, notes WebMD. Available by prescription or over-the-counter, many of these pills are most effective if taken before bedtime when a full night’s sleep of seven to eight hours is expected. Sleeping tablets are potent and cause drowsiness, grogginess and other impairments, and should not be taken if driving or while trying to concentrate.
