We are thinking of putting our 15 year old son on Strattera, I am not thrilled.?

My 15 year old son is having a lot of problems in high school, mainly focusing and comprehending what it going on. He just sits in cl and does nothing. He has always had focusing issues, but he is in danger of flunking 10th grade. My ex-husband has a friend who is a doctor and suggested that we try Strattera. I am worried of course, of the high rate of suicide thoughts. I don't want to make it worse. He does NOT get in any trouble at school, does not do drugs and is all around a good kid. But, he does absolutely nothing at home... to get him to do a mundane task (like putting his own dishes in the dishwasher) is like asking him to mow the back 40! I know that some of this is teenage stuff, but I am worried about this drug. Anyone out there have any experience with it?
