The prescription drug Ambien (zolpidem tartrate) is frequently used to treat insomnia temporarily. It is a member of the group of medications known as non-benzodiazepine hypnotics, which work similarly to benzodiazepines but are less likely to be abused or become dependent on them. Historically, obtaining Ambien required a prescription from a medical professional. On the other hand, Ambien is currently available without a prescription from several internet pharmacies. Usually, these pharmacies ask you to complete a quick online consultation in which you give them some basic details about your health history and sleep issues.
