I just stopped taking tramadol 100mg bid yesterday after weening off it for 3 days. I had been taking for a couple of yrs for hip and knee joint pain and back pain. The following day I applied my first butrans 10 mg patch. its only been 30 hrs with no pain relief at all. Also no side effects to report when starting it. How long should it take before you know if this dosage is going to work or kick in?
