SSRI (Prozac, Zoloft, etc) and SNRI combos (Cymbalta), cause extrapyramidal side effects in some people. This is because the body senses too much serotonin, and for some reason lowers dopamine levels to compensate. The lowered dopamine release then causes Parkinsonian type symptoms of muscle dystonia. This can start in the head and neck mostly including the jaw and tongue. As time passes then it can involve other muscles in the body, and restless legs can occur.
