Hi,
I am on both methotrexate and plaquenil. I have been on plaquenil for over a year and a half and methotrexate since September. I have had no side effects from either one. I get my eyes checked every six months and I am now at once a month on blood work for my liver enzymes (used to be every 2 weeks). I take these for the arthritis associated with my lupus.
I don't know if this helps you or not. If you have any particular questions, I would be happy to answer them.
I wish you well with this decision and the results.
