I've just got my tablets for the next few weeks. One was what I've been having the past month or so.. The manufacturer is Milpham. But I've also received another box, different looking tablets and the manufacturer is Teva. This doesn't help my anxiety, as I have GAD and worry about anything and everything so of course I feel apprehensive about these different ones although they still are Mirtazapine. Has anyone else had this? Also, I've heard about brand name and generic and that some people have noticed a difference... A bit of a silly question, but what is the difference between brand name and generic?
