I called Eli-Lilly today and asked where I might find instructions for safe withdrawal from Cymbalta. The nice lady at Eli-Lilly said they don't publish anything like that. Although she did say that you should never quit that stuff cold turkey.
She said for information on how to safely withdraw from Cymbalta, you need to talk to your physician. I asked if the physicians received instructions from Eli-Lilly on how to advise their patients on withdrawal, and if so, could I get a copy of that document?
She said she didn't think there was such a document, but the physicians will know best how to help you withdraw safely.
There you go. Interesting.
