"I was prescribed Nucynta 100mg while taking Cymbalta 60 mg.  ABSOLUTE MISTAKE!  I have experienced serotonin syndrome at least 3 times in the past year. I initially thought my behaviors were attributed to Cymbalta, but I finally took time to actually investigate serotonin syndrome and felt blessed that I had not hurt myself because I was taking both Cymbalta and Nucynta.  It's very important to learn the side effects and medication interactions of your medicines.  From reading a few posts about Nucynta, I would conclude that a few are already experiencing serotonin syndrome. It's not to be taken lightly, please do your research.  "
