if i were to take xanax 25 mg. prescribed to me thursday night would it be out of my system by sunday evening? driver. i want to be responsible. i have had some life changes that have caused anxiety and my doctor prescribed me to take 25 mg of xanax for only emergencies along with well butrin. however i drive for a living and i don't want to take any chances with my livelihood. i don't want to have any in my system while working. i will not start if there is no way of avoiding this problem. thank you
most helpful answer it would be unlikely that any effects of the xanax would be present three days later since it tends to wear off in 6-8 hours.
