Dear Dr. I am an RN (48 yrs) who is my husbands case manager and advocate. He has been on Fentanyl patches 100 MCG/Hr since 1993. His dosage has never changed BUT when he was treated at UCI and UCLA he was noted to be a early drop off patient who needed q 48 hour dosage. He was on that regimen for years. He now is stuck at 72 Hr intervals due to fear of the state BOM and DEA on the part of his drs. here in NM. I investigated this problem before and was successful in getting his intervals changed. I just saw three papers about a Fentanyl Citrate TAPE called Fentos which is DAILY application and erradicates the peaks, Troughs and drop off phenomena. Is it available in the US? Is conversion to it common and reliable? Looking for solutions to having him basically nonfunctional (ADLs etc) 2/3 or the time due to severe neck and back pain. He has been to pain clinics (Loma Linda, UCI, UCLA USC) and there is concensus he will be on opiates the rest of his life. What about Fentos?
