The antidepressant suicidality warning has an age ceiling most people never hear about
The increased risk was found under 25. Above 24 it was not found, and over 65 the risk went the other way.
Top of the evidence hierarchy, independently funded. how we score evidence
Antidepressants carry a boxed warning about suicidal thoughts and behaviour in children, adolescents and young adults. It came from pooling 24 short-term placebo-controlled trials of nine antidepressants in more than 4,400 young patients: suicidality was reported in about 4% on drug against 2% on placebo. There were no completed suicides in those trials.
The part that usually gets lost is the age boundary, which is in the label itself. The studies did not show an increased risk above age 24, and in patients 65 and older the risk went in the other direction — it was reduced. The warning is real and it is specific, not a blanket statement about everyone who takes one.
Worth asking
Given my age, which side of that line am I on, what specifically should I or the people around me watch for in the first two months, and who do I call if it happens.

Questions
How strong is the evidence behind this?
Resolv rates this source "gold standard". Top of the evidence hierarchy, independently funded. It scores 86 out of 100 on our published rubric. The score is calculated from recorded facts about the source — study design, funding, publication venue, sample size, preregistration — not typed in by an editor.
What is the source for this?
PROZAC (fluoxetine) prescribing information — Boxed Warning: Suicidal Thoughts and Behaviors — U.S. Food and Drug Administration (approved labelling). Published in: Regulator or national health body. The full source is linked on this page so you can read it yourself.
Who paid for this research, and does that matter?
Study design: Regulatory safety determination. Funding: No external funding. The researchers were independent of whoever benefits from the result. Industry sponsorship is one of the most reliably measured biases in medicine, which is why funding carries real weight in the score rather than sitting in a footnote.
Is ssri, snri, atypical_antidepressant, tricyclic, maoi FDA approved?
Yes — this medication carries FDA approval. Approval is always for a specific indication, not for every use it is prescribed for.
