Hello again Dr. Fudin!

My 85 yr old mother is confused, and I know you have an answer. She had been on tylenol w/codeine for a couple of years due to chronic pain like myself. I was concerned about daily tylenol use.  I suggested she ask her Dr. to rx Burtran’s, which her Pcp did recently. She finds it helpful, but not as much relief as the prior med. I’m sure she is on the lowest dose, which may be increased at some point.
She has a supplemental Medicare Rx plan. Burtran’s is a tier 4. She tells me the RX label from pharmacy states “Burtran’s” and “buprenorphine” in parentheses. I told her she may have a “brand”, not a generic. She states she has the generic because it says “buprenorphine” in parentheses and only that on the patch envelope itself. I tried to explain it to her, but she doesn’t understand what I’m trying to tell her. I know there is a generic because I know of a patient that uses it.
Maybe I’m confused???  Help!
Thank you!
