you can look up the causes on the web. I know years ago had a hole in my left retina, doc said due to the plaquenil. healed on its own, and doc decided to put me back on it after a while.

I don't have any. According to my rheumatologist, Plaquenil has a low rate of side effects. In some people it can cause nausea, mitigated by taking it at night with a snack, and in less than 1% of patients in can cause retinal toxicity.

OK, thanks
