I have always taken Zentiva brand 'Plaquenil'. Now my new local dispensary is saying it is in very short supply and that I can only have Teva brand. (I suspect 'economy with the truth' in that I bet there is a financial aspect to this.) Whatever. I haven't taken any Teva yet as I still have a stockpile of Zentiva, and I don't trust Teva brand. Am I right, or am I being paranoid? Thanks.
