Is it safe to take Xanax for anxiety 2 days prior to surgery?

Provided you have been prescribed xanax by a physician who monitors you, you should be fine taking it two days prior to surgery.

Yes that is typically fine. Xanax is a short acting anxiolytic which means it is out of your system pretty quickly. Not uncommonly I have patients take a similar medication the night before and sometimes the morning prior to surgery if they are very anxious. I would not recommend taking it the day of surgery without discussing this with your surgeon. 2 days before shouldn't be a problem. 

As with any medication, check with your surgeon. But in general, this is totally fine. Although the majority of my patients do not take stress relieving medication before surgery, some do. Good luck with everything.
