Can You Tell Who is Going to Have an Adverse Event to The FQ’s?
No. And that is what makes these drugs so insidious. There is still not enough known about ‘how’ the FQ’s damage the human body to develop a test to determine who will have a bad adverse event. Oh sure, there are some factors that seem to play into an adverse event such as CYP polymorphisms which effect drug metabolism, but so far none has proven universal enough to developing an accurate test.
Having said that, I have made some loose correlations from data over the years linking certain groups of individuals to a higher prevalence of an adverse event from FQ’s. You can view this data here. Please note that these lists are not all inclusive.
