Hi Starrysky.

I'm guessing that your uneasiness is a 'Psychosomatic' response to the brandname more than anything.....which of course doesn't make your trepidation any less real.
'Prozac' is an older generation antidepressant, which I believe has been updated in recent times. However, there are many newer generation antidepressants that you may be more at ease taking....and just as effective.
This is most definitely something you will need to discuss with your prescribing Doctor.
