You were weaning him off Prozac slowly weren't you? Maybe you slipped below a tveraputic dose a few days before you stopped. As someone with experience in depression though he does sound depressed so maybe put the SSRI back in - I prefer citalopram though.
Yes we were. The higher dose caused panic attacks and he was missing a lot of school. He has been much better on the lower dose until recently.
Our goal is to try another SSRI. I understand that some SSRIs work better for people than other. Fingers crossed here.
