Study of Fluoroquinolone Adverse Events

We would like to learn more about the adverse events that some patients experience, and others do not, taking fluoroquinolone antibiotics.  Examples of fluoroquinolones include: Cipro or Ciprodex (ciprofloxacin), Levaquin or Tavanic (levofloxacin), Avelox or Vigamox (moxifloxacin), Zymar (gatifloxacin), and Floxin (ofloxacin).  We hope to learn why some people have problems with these antibiotics, while many others do not.  And we hope to learn more about the problem and the mechanism as well as any unexpected benefits. 

We are recruiting 10,000 participants for this study who have taken fluoroquinolone antibiotics, whether:

  • 1) They experienced an adverse reaction during use, and/or after stopping.

-- OR --

  • 2) They have not experienced an adverse reaction (i.e. tolerated fluoroquinolones without apparent problem).

If you meet either of the above criteria, we would like to invite you to participate in this voluntary study so we can further understand the adverse effects of fluoroquinolones. 

The study will be conducted via online survey only, so geographic location does not matter for the study.  For more information, please see our study website at or contact our office at (858) 558-4950, x201.  We would be happy to give you additional information or instructions on how to participate.
