Ambien: Is dependence a concern?

Physiological dependence on zolpidem (Ambien) isn't thought to occur among otherwise healthy adults. In fact, Ambien misuse is almost exclusively limited to people who have a history of addiction. Although the Food and Drug Administration has only approved regular-release Ambien for short-term use, no time limits are associated with a newer controlled-release formulation of Ambien. Some studies suggest that Ambien is effective over the long term without adverse effects, and some doctors prescribe Ambien indefinitely, as long as careful follow-up is possible. If you have a history of addiction, however, long-term Ambien use might not be right for you.
