My daughter, Sadie has been on setraline 50mg for several month, for anxiety. Her psychiatrist just added 1mg of guanfacine for ADD. He has tried other ADD medications in the past with horrible side effects. When I put in the drub interaction of the 2 medications, it said that the zoloft could increase the effects of the guanfacine, and to watch her carefully. I am a bit worried after reading this, but also know her dr. or the pharmacist pick up on drug interactions. Can you advise me if this is ok? Kindly, Kristin
