Zolpidem is commonly sold under the brand name Ambien, although it is also available in generic form. It is primarily used for short-term treatment of insomnia, which is defined as difficulty falling asleep or staying asleep. Zolpidem is not intended for long-term use and is typically prescribed for two to six weeks.

Insomnia can have a variety of causes, including stress, anxiety, and certain medical conditions. It can also be a side effect of certain medications. Zolpidem works by targeting specific receptors in the brain called GABA-A receptors, which help to regulate sleep.
