Vyvanse, an FDA-approved treatment for children with ADHD, has been available for about a year now. Many parents report good results on this long lasting stimulant, with many anecdotal reports of fewer side effects than Adderall XR and some other ADHD stimulants.
The main complaint about Vyvanse is that it had originally only been available in three dosage strengths - 30mg, 50mg, and 70mg. That limited how much you could adjust a child's dose of medicine and meant that if the a starting dosage of 30mg was too much, than the child likely couldn't take Vyvanse.
Three new dosage strengths are now available and should help pediatricians and parents fine tune a child's dose. These include 20mg, 40mg, and 60mg, which means that you can also start a child at a smaller dosage if you wanted to. This is especially helpful if you are switching a younger child who is only taking 10mg of Adderall XR or Focalin XR 10mg to Vyvanse.
