its not the experation date that matters here, the important question is do you have a current prescription for ambien, if not, you hsouldnt' take it. If you need to take it, or need a sleep aid, call your dr, they might even suggest yo ucan in fact use the "expired" pills. Also consider you are probably on different other meds than yo uwere a year ago and there could be possible new interactions, please contact your dr.
