This is an absolute failure on the part of medical science. SSRIs went mainstream in 1988.

By 1992! We knew about withdrawal issues: https://www.wikidoc.org/index.php/SSRI_discontinuation_syndr...

Let's be generous and give it until the 2000s for the knowledge to spread and science to validate; and we're still left with 26 years of blundering around without IMO sufficient warning to patients about withdrawal risks.

I would wager some of the doctors who prescribe today were well past a glint in their father's eye when we started to know about this.
