Hi-I have been taking duloxetine (30 mg a day) for major depression. Recently, my dr upped the dose to 60 mg a day. About 10 days later, I discovered my mood had vastly improved.
This drug did nothing for the pain of lumbar stenosis and cervical spondylitis - However, another drug called Pregabalin (Lyrica) did in a big way-I take upward of 600 mg a day and find I can mostly walk again without much pain or tripping over my own feet. Now, if your dr does agree to prescribe it, they are going to start you on a low dose like 25 mg a day and increase as needed.
Tip: I am not a doctor and not qualified to give medical advice.
That being said, I can only recommend you check with your doctor. At least they will be glad to prescribe something that is not a strong opiate.
Good Luck!
