There's an FDA-mandated warning label for every drug. The current label for Finasteride [1] includes depression only as a "postmarketing experience", which is based on the same data you're reading here (self reports), and is not reliable for determining causality. [2]
There is no current listing for suicide, suicidal ideation, etc.
