My 5yr old is taking metadate 30mg (1 every morning)... My 8yr old is taking Concerta 54mg (1 every morning)... recently their Dr. has added intuniv 1mg (every morning) WITH the medication's listed above... Is this okay to mix intuniv with Concerta and Metadate... I have noticed extreme tiredness in my 5yr old... and some rather nasty meltdowns with my 8yr old??? Is this normal??
