[UPDATED 08/03/2009] FDA notified healthcare professionals of changes to the established drug names for botulinum toxin Type A (Botox/Botox Cosmetic, Dysport) and botulinum toxin Type B (Myobloc) to reinforce individual potencies and prevent medication errors, and provided recommendations for healthcare professionals to consider, plus information for patients, family members, and caregivers.

[Posted 04/30/2009] FDA notified healthcare professionals that after an ongoing safety review initiated in February 2008, the manufacturers of licensed botulinum toxin products [botulinum toxin Type A (Botox and Botox Cosmetic) and botulinum toxin Type B (Myobloc)] will be required by FDA to strengthen warnings in product labeling and add a boxed warning regarding the risk of adverse events when the effects of the toxin spread beyond the site where it was injected.
FDA will also require that manufacturers develop and implement a Risk Evaluation and Mitigation Strategy [REMS], including a communication plan to provide more information regarding the risk for distant spread of botulinum toxin effects after local injection, as well as information to explain that botulinum toxin products cannot be interchanged. The REMS would also include a Medication Guide that explains the risks to patients, their families, and caregivers. FDA is requiring the manufacturers to submit safety data after multiple administrations of the product in a specified number of children and adults with spasticity to assess the signal of serious risk regarding distant spread of toxin effects.
FDA’s evaluation of the data continues to support the recommendations made in the 2008 Early Communication. For more information visit the FDA website at: [Web], and [Web].
