I was wondering about Prozac weekly that I've seen advertised on t.v. lately. Is it time released over the period of a week? Does everyone take it weekly? Different dosages for kidney, liver impairment and elderly? I wonder if many people are using it and what are the benefits vs. regular Prozac (I gathered by its name that it's a weekly dose, I think), side effects, what it is being used for (MDD-Major Depressive Disorder, OCD-Obsessive Compulsive Disorder ? and ?) regular dosages and anything else about it. Also, how is it metabolized mainly?
