Can prozac help my son

My son says he thinks that his depression is kind of a byproduct of having autism so his depression isn't clinical is what I mean..his depression caused by the fact he has autism..thi being the case can taking prozac deal with that? I've steered clear of medication as he has some funny sleep patterns and I was worried he would take too much or not enough  etc at the right time..I live with him I'm his mum don't know I just if anyone else had had to put there child on prozac ?
