Hello Lily
I'm sorry you have these problems and best to call your doctor. It seems that 5%-10% of patients starting Plaquenil or chloroquine can have "musculoskeletal flu- like symptoms of aching and fatigue , but the symptoms resolve within one or two weeks even when the medicine is not stopped"
( Dr Wallace in Dubois p1160)
Another possibility is that you happened to start a flare or that you have an infection.
I am sure I have read that double vision can occur when starting Plaquenil because it temporarily affects the eye side muscles. This should wear off too. I can't find a exact source for this info but it was from Dr Hughes, the eminent London lupologist.
Just to mention that the alternative to Plaquenil is Quinacrine ( UK Mepacrine).
Let us know what the doc says
