A new pill adds to the choices but behavioral therapy can be a better option for some, reports Scientific American.
Last year a new sleep drug called Belsomra came on the market, featuring a mechanism unlike any other pill: it mimics narcolepsy. That might sound odd, but the potential users are many. More than 8.5 million Americans take prescription sleep aids, and many others use snooze-inducing over-the-counter medications. All these pills, including Belsomra, do one of two things: they enhance the effects of the neurotransmitter GABA, known for quieting brain activity, or they arrest the actions of neurotransmitters that keep the brain aroused. Yet it’s not quite as simple as flipping a switch; the drugs have a range of side effects, including daytime drowsiness, hallucinations and sleep-eating. Here’s an overview of the sleeping pills currently available in the U.S.—plus a look at cognitive-behavior therapy for insomnia, which may be more successful than drugs alone.
