I don't know all of them as I'm not a chemist/pharmacist. I just have experience with tramadol as I'm a long time user of it as I can't tolerate a lot of other meds. I also know that I can't take other meds with serotonin as it can lead to serotonin syndrome which can be dangerous. To my knowledge, antideprressants and the muscle relaxer flexeril are all off limits. Hopefully Mrs. D. will see your post and offer a thorough answer to your question.
