9 ( ) See 17 for PATIENT COUNSELING INFORMATION and Medication Guide. Revised: 7/2021 WARNING: DISTANT SPREAD OF TOXIN EFFECT See full PRESCRIBING INFORMATION for complete boxed warning. The effects of BOTOXand all botulinum toxin products may spread from the area of injection to produce symptoms consistent with botulinum toxin effects. These symptoms have been reported hours to weeks after injection. Swallowing and breathing difficulties can be life threatening and there have been reports of death. The risk of symptoms is probably greatest in children treated for spasticity but symptoms can also occur in adults, particularly in those patients who have an underlying condition that would predispose them to these symptoms.
