HI, and welcome
Vyvanse is the same med as Adderall( Vyvanse is lisdexamphetamine, adderall is dexamphetamine), with a different release.
A child may HAVE ADHD, but it is not what they ARE. Never tell a child they ARE ADHD.
Remember too:Do not take Amphetamines with antihistamines, monosodium glutamate(in meat tenderizers and in many chinese dishes), or Vitamin C.Amphetamines should NOT be mixed with Strattera.Amphetamines have been extensively abused. There is a much higher risk of dependence and abuse with Adderall and Vyvanse than with Concerta, Ritalin or any of the other non-amphetamine meds.
And finally, from http://www.rxlist.com/vyvanse-drug.htm"The effectiveness of Vyvanse for long-term use, i.e., for more than 4 weeks, has not been systematically evaluated in controlled trials. Therefore, the physician who elects to use Vyvanse for extended periods should periodically re-evaluate the long-term usefulness of the drug for the individual patient."
My son (16 y/o) began taking Vyvanse 2 years ago. He has ZERO side effects and it does seem to help with his ADHD.
I like that it is not effective unless digested... so if crushed, snorted or whatever people come up with - it won't work. AND teenagers will do this; not necessarily my son but his friends who could steal the meds.
