Can my son take vyvanse (lisdexamfetamine) for add, even though he was just diagnosed with rt bundle branch block? if not, can you recommend any natural supplements?

Cardiologist: prior to starting any new medication, whether prescribed by your pediatrician, psychiatrist, or if you buy it over-the-counter, you should discuss it with your child's cardiologist. Just because something is labeled as "natural" and sold in a "health-food type store" does not mean it is safe. Coordinate all meds and supplements with pediatrician and cardiologist.

None: natural supplements have no scientific values. If your son has right bundle branch, a cardiology consult is needed. He may still take vyvanse (lisdexamfetamine) after careful review
