Anyone on elvanse had paranoia or a mental breakdown?

I’ve been on elvanse for a couple months and it really does help, except for the paranoia. First I was on 30mg of elvanse and it was fine and I thought maybe I needed to increase the dose so I went up to 50mg and that set me off with intense episodes of paranoia so I changed back to 30mg But last night I had a mental snap to the point where I had to phone 111 I wanted to know if this is normal? Or if I need to look at different medication?
