Ambien, also known by its generic name zolpidem, is primarily prescribed for the short-term treatment of insomnia, a condition characterized by difficulty falling asleep or staying asleep. Here's how Ambien is used:

1. Insomnia Treatment: Ambien is commonly prescribed to help individuals who have trouble initiating sleep. It works by enhancing the activity of gamma-aminobutyric acid (GABA), a neurotransmitter that inhibits brain activity. By increasing GABA activity, Ambien helps to calm the brain and induce sleep. Ambien is typically taken shortly before bedtime, with the goal of improving sleep onset and duration.

2. Short-Term Use: Ambien is intended for short-term use only, usually for a period of 7 to 10 days. Prolonged use can lead to tolerance, dependence, and withdrawal symptoms. Healthcare providers typically advise using Ambien intermittently or as needed, rather than on a daily basis, to minimize the risk of these complications.
