 Sometime after 2000, Shire closed the Rexar manufacturing facility and outsourced the manufacturing of "brand name" Adderall to a vendor in North Carolina.In fact, no Shire manufacturing facility (other than the Rexar facility it had acquired) produced immediate-release Adderall at any time.Other companies had begun manufacturing generic versions of Adderall, and the trade name was eventually sold to Barr Pharmaceuticals (acquired by Teva in 2008).
