An Introduction to Xanax XR Side Effects
As with any medicine, side effects are possible with
Xanax XR® (
alprazolam XR). However, not everyone who takes the medication will experience side effects. In fact, most people tolerate it quite well. If side effects do occur, in most cases, they are minor and either require no treatment or are easily treated by you or your healthcare provider.
(This article covers many, but not all, of the possible side effects with Xanax XR. Your healthcare provider can discuss a more complete list of Xanax XR side effects with you.)
