Acetaminophen / propoxyphene
"I have been on Darvocet N-100 for about 30 years for rheumatoid arthritis. It has controlled most of the pain except when I'm in a full fledged flare up. I take it with methotrexate (which controls my arthritis) and now my insurance company has denied to pay for it. I did send a letter from my doctor and they still denied it.  I know this drug works for me and they suggest I change to Percocet which they pay for and it doesn't work so guess I just endure the pain. Thanks Darvocet for the pain free years."
