Ive been on the Butrans 10mcg patch for about a year now. In addition to the round-the-clock patch ive been taking 5-10mg of Norco about once every1-2 days. The patch works so well for me the BT meds only need to be minimal.
So I went to go pick up my usual prescription of Norco and the head pharmacist comes out to me and told me he was confused why I was taking hydrocodone with the Butrans. He said that Butrans is both a agonist and antagonist for opiate receptors so it gives pain relief but also blocks other painkillers from working. He said that it will make the Norco work significantly less but I told him I never had a problem with it. He still gave me the medication as normal but gave me a print-out explaining how buprenorphine interacts with hydrocodone.
The print out sheet stated that buprenorphine MAY limit the effectiveness of the hydrocodone. So it seems its not an absolute rule and I could be the exception.
I still think the Norco works just fine for me, plus my Doctor prescribing has an extra degree in pharmocology so I dont think he would mess up on something like this.
Has anyone ever noticed the interaction/cancelling effect of buprenorphine? or are you like me where it seems to work fine concurrently with other painkillers?
