It is possible that you may experience some or none of the Plaquenil side effects listed in this article. Unfortunately, there is no way for your healthcare provider to know beforehand if you will have side effects from a medicine that you have never tried.

While it may not be a side effect of Plaquenil, your healthcare provider will be able to diagnose and treat the problem.
