They was going to put him back on strattera, but before they started it they wanted to check everything out since he has had no blood work up in a long time. The doc was confused by the levels to , but at this time he said that we will wait for one month and then retest the levels again. My son has not been sick this summer at all but during the winter months it seems like he is sick more then he is well. I have heard that the strattrea can cause damage to the lilver, but he was only on it for a few months and has been off of it since march. We had to stop use due to a rash.
