IRVINE, Calif. -- Allergan, Inc. (NYSE: AGN) today commented on a petition filed by Public Citizen yesterday with the U.S. Food and Drug Administration (FDA) suggesting additional label changes and a written communication to physicians regarding botulinum toxin products.

The petition addresses all botulinum toxins approved in the United States and relates to labeling matters involving numerous botulinum toxins marketed globally. Every botulinum toxin is unique and has its own safety and efficacy profile. Allergan can only comment on its own products, BOTOX([R]) and BOTOX([R]) Cosmetic (botulinum toxin type A) (collectively referred to in this press release as "BOTOX([R])").

There are no safety issues raised in the petition that are not already addressed in the labeling for BOTOX([R]). Allergan takes its FDA-mandated labeling obligations very seriously. The current label for BOTOX([R]) provided to physicians in the United States provides detailed information and appropriate guidance on the proper uses of BOTOX([R]), including detailed directions for approved medical uses, contraindications, warnings, precautions, drug interactions, and reported adverse event information.

Allergan is in frequent dialog with the FDA to ensure proper labeling for its products and also submits information on all adverse events that are received whether or not they are considered related to the drug. In collaboration with the FDA and other regulatory agencies around the world, Allergan regularly reviews safety information and updates the labels for its products as appropriate.

BOTOX([R]) has a long-established safety profile and has been approved by the FDA for more than 17 years to treat a variety of medical conditions, as well as for aesthetic use (glabellar lines) since 2002. With more than 3,000 publications on botulinum toxin type A in scientific and medical journals, results of dozens of clinical trials involving more than 10,000 patients, and having been used in clinical practice to treat more than a million patients worldwide, BOTOX([R]) is a widely researched medicine. BOTOX([R]) has been approved for 20 indications in more than 75 countries and is prescribed to patients who suffer from a range of serious or debilitating disorders, as well as to those with aesthetic needs.
