I devleoped an allergy to Plaquenil after six months.    Recently, I was prescribed Chloroquine.   I know  the literature  says not to takw Chloroquine if you are allergic to Plaquenil, but my doctor thinks there is something in Plaquenil that is not in Chloroquine that is responsible for my issue w/Plaquenil.

Hope he is right
