US National Institutes of Health State-of-the-Science Conference Statement on Manifestations and Management of Chronic Insomnia in Adults (2005)

“[CBT-I is] as effective as prescription medications are for short-term treatment of chronic insomnia. Moreover, there are indications that the beneficial effects of CBT, in con­trast to those produced by medications, may last well beyond the termination of active treatment. There is no evidence that such treatment produces adverse effects”

“Studies demonstrating the usefulness of … medi­cations for either short- or long-term management of insomnia are lacking. Furthermore, all of these agents have significant risks. Thus, their use in the treatment of chronic insomnia cannot be recommended.”
