I have been having trouble with asthma and today I took a Vyvanse to see if it could help me focus on work.  The asthma problems I was having the last two days did not occur today at the same time.  Is it just a coincidence.  I do not take Vyvanse regularly.
Hi, See Vyvanse is a CNS stimulant Chat Doctor. If you are thinking if it's gonna work in asthma, then there is no role of it in asthmatic attacks. If you have occasional asthma but still you should take MDI inhalers or Rottweilers prescribed by pulmonologist. Yes never take CNS stimulant
