In reply to Xanax XR--Timing of 2mg dose, posted by smeans on October 1, 2004, at 15:05:18
Xanax XR reaches maximum plasma concentrations 5 - 11 hours after you take it. I'm on 2 mg/d and i take a 1 mg XR tablet in the morning and a 1 mg XR tablet at night which keeps blood levels pretty linear. I strongly believe the XR version has to be taken twice daily from my own experience. Also note that you might need a slightly higher dose on XR compared to IR for the same effect.
