My pain doctor started me on the Butran Patch and told me to continue to take my Norco for breakthrough pain. I have read conflicting information. Will this put me into a withdrawal from the Norco? I am worried because I am going on vacation and I do not want to have any complications. He prescribed the Butran so that I would have better pain coverage but when I went to the pharmacist he said it is used to treat opioid tolerance and will cause withdrawal from other meds. Is this true?
