"i started my son on guanfacine 1mg at night. he was 7. this is after trying a prozac/ clonodine mix to treat his adhd, which i hated because all my kid did was sleep. with the guanfacine, which is the generic for intuniv, he is doing great!! the 1mg at night didn&#039;t work well though. after all the adjustments i made, i ended up giving him a 1 mg in the morning and a 2 mg at night. this combo works great and my kid does not sleep all day. in fact, he hardly naps-he has made friends in school and is doing great!!"
