Generally, Ambien withdrawal symptoms can begin within a few hours to a few days after the last dose and may last for several weeks to months. The most intense withdrawal symptoms usually last for the first few days to a week, with symptoms gradually decreasing in intensity thereafter. It is important to seek medical supervision when discontinuing Ambien or any other medication, as sudden withdrawal can be dangerous and potentially life-threatening.
