As I have stated in the past....I'm in charge of mom's meds and try to stay on top of this the best I can. I call in refills as necessary since auto refill caused too many problems. Mom has been on Xanax for the past five months......taking one every evening. When she was down to five pills I called in for refill. I found out today that her PC would not refill the prescription and I am concerned about possible withdrawal. Doc is not in office tomorrow, so I'm at a loss until Monday. Just curious if anyone else has experienced stopping this med abruptly? Am I overreacting by being concerned about potential withdrawal?
