Confusing question: I'm sorry but i was able to understand everything except the "hr50" part of the question? If you are asking about passing a drug screen, xanax (alprazolam) will show up for up to a week or more but if is a prescription medicine, then she has nothing to worry about as her doctor will give her a note stating that she is authorized to take it. If that is not your question please re-write it a little clearer.
