I have been on Plaquenil for sometime now and the only side effect I have noticed is thinning of my hair and splotchy skin. I am not sure of its full effect since I also take Prednisone every day. I do get my eyes checked every 6 months to make sure all is well in there and I actaully do keep a copy of the graph with the dot in it on my fridge....just a little extra precaution.
