ADDERALL® (Mixed Salts Of A Single-Entity Amphetamine Product) Supply Clarification

December 1, 2011



Shire plc, the global specialty biopharmaceutical company, responds to questions about reports of a supply shortage of ADDERALL® (mixed salts of a single-entity amphetamine product) Tablets, CII.  ADDERALL® is an immediate release formulation and is sometimes referred to as “ADDERALL IR.”  While Shire is aware of the reports of the supply shortage, Shire cannot provide additional information because Shire does not own, manufacture or distribute the medication.  Shire suggests that questions about the supply shortage be directed to the companies that manufacture and/or distribute ADDERALL IR.

Shire developed ADDERALL IR, and the FDA approved ADDERALL IR as a treatment for ADHD in children in 1996.  Shire divested ADDERALL IR in 2007 and no longer owns, manufactures, or distributes ADDERALL IR or any of its generic forms.  Several pharmaceutical companies currently manufacture and distribute generic forms of ADDERALL IR.  According to the FDA, those companies are Sandoz, CorePharma, and Teva. Additional information about the supply shortage of ADDERALL IR is posted on the FDA Drug Shortages website: http://www.fda.gov/Drugs/DrugSafety/DrugShortages/ucm050792.htm

Shire also developed and currently manufactures ADDERALL XR® (mixed salts of a single-entity amphetamine product) Capsules, CII, an extended release capsule formulation that was first approved by FDA in 2001 as a treatment for ADHD in children.  ADDERALL XR® is available at pharmacies and current inventories of all strengths of ADDERALL XR® are sufficient to meet patient demand.
