I may be wrong but I think you are correct that the name brand adderall
made by Shire will be discontinued and replaced by Vyvanse. That being said, you will continue to be able to get the generic brands. It was explained to me that the whole reason Vyvanse was released was because adderall
was coming off patent and Shire needed a "latest and greatest" to compete with the generic manufacturer
s. I'm sure I'll be corrected if this is wrong but that's the story I was told.
