I took various meds when I was a kid. Both my sons are on meds now, but not for "autism", they're taking mood stabilizers for bipolar swings and both take something to help sleep. One on a generic form of ambien, and the other can get by on melatonin.
The thing is meds don't just "fix" everything. If you have a co-morbid condition that is caused by brain chemistry being out of whack, the only way to correct that is with meds. If you are just talking about "taking meds for autism" I'm not aware of any such treatment that is effective.
