If you are taking Xanax which, is a drug that depresses the central nervous system and calms the brain, and have also dealt with sleep paralysis, the reality is that it can’t actually harm you. After seconds or minutes, you regain the ability to move again, and no harm is done to your body.
Sleep paralysis is basically a temporary partial or total inability to move your body or limbs. Sleep paralysis is not an official listed common side-effect of using Xanax, however many people have reported experiencing paralysis while using Xanax. If sleep paralysis is causing you anxiety then it’s worth having a talk with your physician about changing your prescription.
