5 htp and eosinophilia myalgia syndrome. how long do you have to take 5 htp, before you get eosinophilia myalgia? i have been taking it for 4 day now.

Eosinophilia myalgia: Eosinophilia myalgia syndrome is a rare allergic disorder associated with consumption of l-tryptophan, 5-htp or a contaminant of supplements containing these compounds, possibly only in individuals with a genetic predisposition. Chances are you will not develop this rare condition. But if you do get muscle pain or shortness of breath while on 5-htp, you should stop taking it and go see a doctor.
