I've never heard of that. Why would they be testing an infant for their reaction to an antidepressant drug? Just curious.
I would have hoped clinicians would start at the lowest possible dose, and titrate up. I've certainly heard of the "you need about xx mg, use this dose" first doses, tho.
To me, this is Yet Another reason one should never receive medical advice alone, especially when thinking is impaired. That trusted friend / partner needs to ask the hard questions of the prescribing clinician; but rules make any 3rd party except spouse difficult for adults.
They often accompany one another. I've had panic attacks in the past, and was diagnosed with generalized anxiety disorder. I can't claim that bupropion fixes panic attacks proper, and I'm not a doctor, but it does help me with my depression. (I haven't had a panic attack in a long time.)
It's not a silver bullet; you can still find yourself in mentally stuck states, the difference is the physical side of things seems to be 'gated' at the low end so that your spiraling down isn't as deep as it is before. There's still a lot of work to do to recognize + slow that descent, but it is a tool to help with that.
Wellbutrin and NDRIs typically aren't that great for anxiety, but they can help.
