My son just recently put on meds namely clonidine 0.1 mg 1/2 tab at night and concerta 18 mgs. once a day. There are some positive response such as improvement in his writing skills, less hyperactive but I am concerned about negative effects such as being upset if he does not get his way,more obsessive, and sometimes he seems to have problem verbalizing himself. his teacher said the same thing. I dont know what to do. I am torn about this, should we stop the meds or adjust it. Should we get rid of the clonidine because I dont think it helps at all, but I was reading that we shouldnt just stop it because it can cause sudden rise in blood pressure. Please help.
