I don't think there are any empirical studies linking extended or heavy Prozac use to certain behaviors in the future, at least not that I'm aware of.
As with almost all drugs there are warnings about who should take a specific prescription drug and that decision is made by a doctor, and possible side effects when taking or weaning off of the drug, which should be made under the supervision of a doctor.
Sorry I can't help you locate any information about future behaviors.
Given that Prozac is most used for behavioral issues, you might ask this question on Health Central's Depression or Bipolar, sites.
