I'm currently using 100 mcg Fentanyl every 48 hours along with 10mg/325mg Hydrocodone/Apap tabs @ 1 per 6 hrs. This is for long-term chronic pain associated with lupus/rheum arthritis and degenerative disk disease. I've been using patches for about 3 years. Thanks to Medicare's 'gap' I can no longer afford to pay for Fentanyl patches. Even generic ranges from $385 to $872. I need to know which drugs are less in price, but are comparable to Fentanyl in order to transition with "hopefully" very little withdrawal. That scares me tremendously. I had an opportunity once to experience a Fentanyl withdrawal for only about 12 hours. That was more than I needed. Any ideas? Thanks so much.
