Ambien (generic name: zolpidem) is a prescription medication used to treat insomnia, particularly for those who have difficulty falling asleep. It belongs to a class of drugs called sedative-hypnotics and works by affecting the brain's neurotransmitters to promote relaxation and sleep. Ambien is usually prescribed for short-term use, as it can be habit-forming and may cause side effects such as dizziness, daytime drowsiness, or memory issues. It is important to follow a doctor's instructions closely when using Ambien.
