"my 7yr old who is autistic, has adhd and epilepsy has taken guanfacine for about 3 years now.  since 12/6/2016 she has been taking 1mg er and we just increased to 2mg er on 1/7/2017.  my girl is a new child, can focus more, is learning more, and is getting much better daily reports from school.  she is tired by the end of the day but i think it&#039;s due to her still adjusting to the dosage.  i am extremely happy with our results!"
