Guanfacine
"My son was prescribed this medication for the second time.  2 years ago along with amphetamines while in kindergarten and he became very aggressive to the point he hit me, he had terrible anger outbursts, and a LOT of issues at school.  But I was going through a divorce and 2 years later we decided to give it another chance in case it was more behavioral; however, after 2 weeks, I receive an email from his teacher about how his behavior changed dramatically for the worst. Again we stop.  This time we know he's in a happy home environment and his behavior is much better so it became obvious it's the medication.  Not for my son. He's on vyvanse only now and we'll see how that goes."
