Wheninrains, In my experience, I have never heard of a reputable rehab refusing anyone for taking prescribed medication. Were you with your Son that day he was not admitted and know this to be the truth? Medication prescribed by a Dr. for anxiety has no bearing on treatment for alcohol addiction. I would look into that. While I was in rehab, many of the "clients" were on meds and it was handed out to them every morning by a staff member.
