Ambien (zolpidem) is a prescription sleep medication used for insomnia, particularly difficulty falling asleep (sleep onset insomnia). It is a non-benzodiazepine sedative-hypnotic (often called a “Z-drug”) that works by enhancing GABA activity, promoting relaxation and sleep. It acts quickly and is typically taken right before bedtime, with effects lasting several hours.

Ambien is effective for short-term use but is generally not preferred for long-term management due to risks of dependence, tolerance, and next-day impairment. Potential side effects include drowsiness, dizziness, sleepwalking, and other complex sleep behaviors (e.g., eating or driving while not fully awake).
