I am new to this and searching for answers. My 13 year old is on Abilify(low dose) and recently (2 months or so ago) the doctor added zoloft. The combo seemed to work well but the weight gain has been HUGE. She is a taller child but 150 at 5'6 is too high and obesity is only going to add to the social issues she already has. The doctor said the zoloft increases the side effects of the abilify. The weight gain has been 20 lbs so far. This was a child who was a picky eater and now eats EVERYTHING. The doctor said diet and exercise, not that simple believe me! If there are four pears in in the fruit bowl she will eat two at a time. She cannot help herself and worse yet she talks about food constantly in an obsessive manner..Anyone had this experience?
