IRVINE, CA: Allergan and Chandler Chicco are reaching out to physicians and patients to reassure Botox users that the product is safe.
The crisis effort went into effect after four people contracted botulinum poisoning at a Florida medical facility. Botulinum is the substance in Botox that paralyzes muscles that cause wrinkles.
Officials are now investigating whether the facility used a homemade Botox substitute, but Allergan's share prices have fallen amid the crisis.
A Chandler Chicco executive could not confirm whether sales of Botox also took a hit.
Since the crisis broke, Allergan has been issuing statements and developing Q&As to stress Botox's 15 years of safety data, said the executive, who asked not to be named.
The American Society of Aesthetic Plastic Surgery has also issued a statement urging patients to beware "unqualified and sometimes unscrupulous practitioners." It has also stressed the safety of Botox.
