"my son is 15 now and we have struggled for years with his adhd. he has now been on strattera for 2 years and has gone from straight d&#039;s in maths to a in achievement he can concentrate more retain information and does not lose it as he uses to. i have seen no side effects at all. at one point he went off it, lasted 5 days then chose to go back on it as he could tell that it helped his behaviour and way of dealing with things. i have only good things to say about strattera."
