Hi there, thanks for asking. Subutex is one of the brand names for the generic name of Buprenorphine. Although both refer to one molecule, it sometimes happens that the potency of a generic medication is a little different from the brand. It is good to know about it in order to readjust the dose if necessary. Since withdrawal symptoms are very unpleasant, even small changes in the dose might become disturbing and if somebody is not aware of that, it might cause panic. Fortunately, buprenorphin (or Subuttex) act partially positive and partially negative on the receptor. It is positive factor which makes any change in the dosage easier than other drugs. I hope you decrease it voluntarily in a good time in the future as well, since it is quite possible with this medication. In long term, it can affect your liver function so it better not to be taken life time. I wish you a good health.
