adhd
"My grandson was prescribed 1 mg Guanfacine at 
age 9. He was a skinny, active kid. Almost immediately, he began to gain weight. It was most noticable in his face, stomach, and rear. Within 6 months, he had gained 21 pounds. I didn't notice much of a decrease in activity. Even ,though weight gain was not listed as a side effect, there was no other reason for the rapid increase in his weight. No change in diet etc. When I googled weight gain and Intuniv, I found many other parents complaining of the same thing. At age 10, he developed gynecomastia. That was it for me! I discontinued the medicine, and I would never consider using it again."
