FDA probably won't be moved, but this was published in the NY Post:

Can someone tell me why this should happen?
I know post-finasteride syndrome is a thing that's plausibly real and poorly understood, but has anything happened recently? Why would the FDA revoke approval over such a thing?
On priors (plausible mechanism + people happily using it) I expect it to be effective, is the effectiveness being called into question?
@Ophelia Hi, I'm replying a year later! There was a Citizen Petition pending at the time this question was created. The petition called for taking finasteride for hair loss off the market or adding a black box warning. FDA responded in 2022, nearly 5 years after the petition was submitted. They did not take the drug off the market or add a boxed warning, but they did add a warning about suicidal ideation and behavior as reported by Reuters:
Regulators in various countries are reviewing the drug's risks and/or adding warnings (e.g., the UK, France and Canada).
