Over-the-Counter Sleep Aids | American Sleep Association

Over-the-Counter Sleep Aids. Many people take non-prescription ('over-the-counter') sleep aids, with a market of over $400 million annually in the U.S. Most commonly these are antihistamines, usually diphenhydramine but also doxylamine. Since these medicines don't require a prescription, many people assume that they are both milder and safer.
