I have been taking the 12 mcg fentanyl patch for 3 + years now. When the doctor tested my blood, it did not show up. I don't understand these results because I faithfully use the patch for cronic pain from a radical neck disscection I had in 2001. I've tried doing the 25 mcg, but makes me very sick. The 12 mcg fentanyl patch doesn't help much with the pain I feel, and if it's not showing up in my blood work, does it mean it's not working?

I am no expert, but from being on the fentanyl patch for over 10 years, at doses from 75 mcg to 125 mcg I can tell you that 12 mcg is a very low dose. I am impressed that this dose helped you for the 3+ years. It's too bad the 25 mcg dose makes you sick - the fentanyl patch is a very effective pain reliever. I'm sorry I don't know the specifics of lab testing for fentanyl but this patch is a very low dose. If it isn't helping much for pain relief it could be that the dose is too low to register. In my opinion -
