5 yr old adopted grandson, was exposed to meth. sees a pediatric psych. now for outburst, hitting, running away, tantrums and the list goes on. The psych. has tried numerous medications, NOTHING helps...I m at my wits end....I think he needs something to calm him, to control anxiety but all I get is Lithium and everthing that leads up to lithium...Adderall...I can t list all of them. Is there not a simple anxiety reliever medication that can help children....
