Blocking 5alpha-reductase by finasteride treatment may have broad consequences for the nervous system.
[W]e have evaluated in male rats the effects of a subchronic treatment with low doses of finasteride.…and the consequences of its withdrawal.…on neuroactive steroid levels…. Interestingly, at the withdrawal, some of these effects persisted, and different changes in neuroactive steroid levels, and in the expression of receptors, were also detected.

Propecia should not have been authorized in the first place, and its approval should be revoked as soon as possible.

Propecia should have never been approved, and its authorization should be revoked as soon as possible.
