It isn't quite a clear case, but the combination of symptoms is within the range of posibility for this rather variable disorder, and I believe it sometimes goes on and on as in this case. There is a posibility of treatment if it is.

> Serotonin syndrome is a potentially life-threatening complication of psychopharmacologic drug therapy. The syndrome is produced most often by the concurrent use of two or more drugs that increase brainstem serotonin activity and is often unrecognized because of the varied and nonspecific nature of its symptomatology. Serotonin syndrome is characterized by alterations in cognition, behavior, autonomic nerous system function and neuromuscular activity. Patients with serotonin syndrome usually respond to discontinuation of drug therapy and supportive care alone, but they may require treatment with a specific antiserotonergic drug such as cyproheptadine, methysergide, and/or propranolol.
> ...Serotonin syndrome usually develops shortly after either an increase in the dose of one or the addition of another serotonergic medication. In half of the published cases, symptoms began within two hours of a change in medication. In only 25% of the cases was the onset of symptoms more than 24 hours after a change.
> ...The diagnosis of serotonin syndrome is based entirely on a strong clinical suspicion and the exclusion of other medical and psychiatric conditions. The typical patient with serotonin syndrome demonstrates altered behavior and cognitive ability, autonomic nervous system dysfunction, and neuromuscular abnormalities. Some patients report recurrent mild symptoms days to weeks before symptoms become more severe. In a few cases, patients rapidly progress to multiple organ failure and death.
> ...No specific tests are available for the diagnosis of serotonin syndrome. Elevated serotonergic drug levels are not required to produce serotonin syndrome, and in over 90 percent of cases in which drug levels were measured, levels were within accepted therapeutic limits.
> ...Consider use of antiserotonergic medications...Cyproheptadine is consistently the most effective agent in humans.
Suggest you see a pdoc immediately, who knows about psych drugs as well as medical problems, to find out if your fluid retention and other problems are due to Serzone, serotonin syndrome, or something else. Hope things get better for you!
