My difficult child had his Intuniv increased from 2 mg to 3 mg on Sat. Today is day 4. He takes it first thing in the morning. Today he is very lethargic. I just checked his BiPolar (BP) with my cuff and got the following: 73/47, HR 74 66/38, HR 57 (this one he was lying down) He is 9 yrs old. 62-65 lbs. This seems scary low to me - but I don't know what his baseline reading is. I googled normal ranges for kids and this seems low according to those. Any ideas/suggestions? I don't want to panic - but I am. Any advice?
