I have a foster son that is now 24 years old and is now having a great problem with weight gain and blood pressure problem since he was taken off concerta about 3 years ago and placed on strattera and at that time his weight was fine and no problems with BP weight. He is now on a low BP medication by his PCP. I have brought this to the attention to the pyschiatrist- but she will not change him back to concerta..I have niot notice any change in his personality...He has gained over 30 lbs. in the last 2 years and as I said the BP is a major problem to me and him since he cannot tell me if he has a headache or dizzy. I am afraid for his physical health!!!!
