Need more info. What specific problems have you had? A more detailed explanation from you is needed before an appropriate answer can be given.
See below. Alternatives are medications that suppress your immune systems. If you were only on generic Plaquenil which is hydroxychloroquine, sometimes patients can be switched to brand name Plaquenil which can be tolerated better particularily if GI side effects occured. It all depends on what side effects you explained on whether switching would work. Talk to your doctor to see if this is an option.
