Ambien, also known by its generic name zolpidem, is a medication primarily prescribed for the short-term treatment of insomnia. It belongs to a class of drugs called sedative-hypnotics, which work by slowing down brain activity to induce sleep. Ambien is primarily prescribed to help people who have difficulty falling asleep or staying asleep. It's typically used for short periods, such as 1 to 2 weeks, to avoid dependency and tolerance. Ambien is intended for short-term use due to the risk of dependency, tolerance, and potential side effects. Long-term use can lead to dependence and withdrawal symptoms.
