I just started taking Plaquenil a few weeks ago. I stared with 100mgs every second day for a week then 100mgs daily for a week. Now I am taking 100mgs and 200mgs on alternate days. My aim is to take 200mgs daily. I noticed this morning that I had a rash (red spots) across my chest. I read that taking Plaquenil can cuase a rash although this is a less common side effect . Has anyone else experienced this?
