I would be very cautious advising SSRIs for anyone, especially developing children, considering my own experience (on sertralin), which was complete disappearance of a libido, and massive weight gain, +40kg (70 -> 110) in ~10 months. 5 years later I still have not undone the damage from it.
Yeah but it's something that affects people differently. I took escitalopram and my libido was a bit reduced but mainly it became harder to orgasm. That was not all bad, it's nice to be able to last an hour and a half :) I was already heavy but didn't gain any more weight. I did lose some when I moved to other stuff though.
But these side-effects just need to be checked for (and the libido issue isn't relevant to under-teens anyway).
How you acknowledge serious side effects some people have, sweep them aside with "but some people don't," and act like getting children on lifelong medication won't result in them having adult-relevant side effects once they're adults is mind-blowing.
