What causes elevated heart beat while on treatment for ADHD?
human
my almost 17 year old son is on Vyvanse for ADHD.   He has also undertaken a fairly rigorous exercise program, up to 2-3 hours of aerobic activity and weight lifting a day.  He finds his heart rate gets as high as 200, no apparent sx that I know of.   Dangers?  Thoughts?  Concerns?

Nope it is comoletely normal. If Heart rate more even during rest than thing to worry. So dont worry.  Hope my suggestions helpful and thankful to you. Take care. Don't forget to give ratings.
