re: Any pharmacists or child psychologists in the house? Question re: Lexapro

What symptoms is your child exhibiting?

Aggression and social issues have been successfully treated with low dose propranolol in autistic individuals. It doesn't directly mess with brain chemistry like ssris. It's a blood pressure medicine and the main risks are low blood pressure and low heart rate.

If the aforementioned symptoms were what the issues were, I'd try propranolol before an ssri.

You may have to find a psychologist with experience with it willing to prescribe it for this. It's off label (not approved by FDA) but for the people it's worked for, it's been life altering (in a positive way).

To answer your actual question, I'd be hesitant to try an ssri in a young child. The suicidality is mostly a depression thing with a different mechanism than you'd see in autism, so I doubt you'd see that issue, but altering brain chemistry like that in a developing mind causes me pause.
