I have read that the only difference between prescribed Prozac and the generic form is
that the fillers are different. Maybe increasing your prescription dosage would give you
a greater amount of the pure product which might offset any fillers. It's worth asking
about, in my view.

Sorry you're having to go through all this; I hope you'll feel better soon with better
medication. Your psychiatrist needs to know all this, and you might think about
talking to a gynecologist about supplementing hormones to help you through these
stages of change.
