I'm new to Hughes Syndrome and it seems I have quite a lot of questions. My latest being: I started on 200mg/day Plaquenil 12 days ago and am experiencing what would seem to be very unpleasant side effects. I get horrible burning sensations in my stomach area; have started to bloat up by the end of the day, very painfully, until I pass copious quantities of wind; have developed some sort of clear mucus/phlegm thing in my throat; but what bothers me most is the truly foul taste in my mouth - started off as metallic, then developed to what can only be described as 'rotting rat' and now seems to be like a four letter word beginning with 's' which I shan't type here. Help! Can anyone tell me if these effects are common and whether they are likely to go away after a while? Or offer advice?
