our son is now 16, and has been taking meds for ADHD, ODD and (as of last year) bipolar disorder. He is taking Risperidone, 1mg am, 1mg pm. Lithium 450mg am, 300 mg pm. and now, thanks to the lithium use, his is taking levothroid 25mcg once a day for his thyroid? I would like to know if this is too much meds and the length of time he's been on them. He is STILL aggressive, mean, abusive, loud and raging.. I would like to know if this combo of meds is making him worse? he also has a speech problem, as to where he tries to tell us about his day at school, and he cant get the first word out,, he gets stuck on it with his mouth open, but nothing comes out.. this is happening more and more lately as well as his aggression. His father and I are at the end of our ropes. He is 6"4 in. has not gained weight because of the meds, but he isn't getting any better. he has been on concerta, intuniv, Depakote in the past, none of which helped. any one else out there notice if they're child has gotten worse while on the meds. I can't find any drug interactions website to help me out with this..
