Serotonin Syndrome

  The medical term "serotonin syndrome" seems to be used too loosely and in appropriately, especially on the internet. Make no mistake "serotonin syndrome" is  a true life threatening emergency that warrants immediate hospitalization with aggressive life saving intervention.

SYMPTOMS

  Diagnosis of serotonin syndrome depends on three physical findings being present at the same time on the medical examination, All three of following categories must be present to make the diagnosis to include, "mental status changes", "autonomic instability", and "neuromuscular aberrations".

  • The first of the three medical findings that need to be present are mental status changes. Examples include agitation, hallucinations, and coma.
  • The second of the three medical finding that need to be present is autonomic instability. Examples include tachycardia, labile blood pressure, and hyperthermia. It is noted that most patients have core temperature of 108 degrees Fahrenheit or higher.

  • The third of the three medical findings that need to be present is neuromuscular aberrations. Examples include hyperreflexia, incoordination and/or gastrointestinal symptoms such as nausea, vomiting, or diarrhea.

CAUSE

  The primary cause of serotonin syndrome is administration of a neurotransmitter reuptake inhibitor with a drug that blocks neurotransmitter metabolism (primarily MAO inhibitors). There has been no reports in medical literature of it developing during the ingestion of nutrients with drugs.

WHAT DOES IS NOT THE CAUSE

  There is no reports in the medical literature of nutrients 5-HTP, tyrosine, levodopa, or cysteine when taken with or without drugs causing serotonin syndrome. Contrary to the urban legends posted on the internet use of 5-HTP, tyrosine, levodopa, and cysteine alone or in combination with any drug, including MAO inhibitors, does not cause serotonin syndrome.  End of discussion.

..AND TO THE RIDICULOUS

  About two years ago there was a report from a doctor whose patient had gone to a pharmacist and was not feeling well that day. The pharmacist told the patient she had serotonin syndrome and would probably feel better in a day or so. The patient went home and felt better in a day or two. This in no way was serotonin syndrome. If it was that pharmacist was negligent for not arranging to get that patient immediately hospitalized and treated for a true life threatening medical emergency.

  The term "serotonin syndrome" is indeed used too loosely by many who do not have clue what it really is and how quickly it can kill people if not managed properly. Virtually all patients with serotonin syndrome have a core temperature of greater than 108 degrees Fahrenheit.

SIDE EFFECTS

  In taking 5-HTP, tyrosine, levodopa, and cysteine there is no side effect that should require stopping on a permanent basis if managed properly. At the left links to management strategies and person hand outs relating to side effects.
