So I looked up drug interactions with tramadol and citalopram (the antidepressant im on) and it said its a major interaction that increases my risk for serotonin syndrome. I'm wondering if i should be worried. also wondering why the darn tramadol is not working. I feel no difference in the level of pain. I don't have a regular doctor, and i saw the urgent care doctor. so i am wondering who i should call about the tramadol not working. should i call the urgent care place, or a general doctor ive never seen before?
