Is it possible that antidepressants have some extremely subtle transgenerational epigenetic effects? Maybe, but comparing healthy patients to SSRI-treated remitted depressed patients is a bit of a red herring anyway. The real comparison would be between SSRI-treated patients and untreated depressed patients, because healthy people aren't prescribed SSRIs. We do know untreated depression is very harmful to people and their families, so speculating about immeasurably small negative effects of SSRIs while ignoring the massive and very real cost of untreated depression would be a mistake.
