I have been on the fentanyl patch for 9 years. Just recently the dr upped me from 75 mcg to 100mcg - the patch takes care of my pain WHEN it isn't falling off! Has anyone went from the fentanyl patch to Zohydro? I'm worried sick about experiencing withdrawal symptoms if I switch meds. Also, worried that high levels of pain would return. I love the patch it just doesn't love me apparently. I appreciate any insight you can share.
