It seems that the anti-Roaccutane lobby are continuing their march towards having it banned. It appears it may cause "depression" in mice. I'm not sure how one tells that a mouse is depressed. But, apparently, one can.
I must confess an interest here. I was prescribed Roaccutane in my early twenties and its effects were astonishing. I have friends who have also benefitted from it - some to an astonishing degree.
Were it to be made even harder to obtain than it is today (only dermatologists can prescribe it in the UK) then I would be most upset.
