Severe muscle weakness belongs to rather rare but at the same time dangerous side effects of Dysport in forehead, mid-face, perioral zone, or any other facial and body area.

Thus, a patient is expected to contact a healthcare provider as soon as possible if noticing any swallowing or breathing difficulties after the procedure.
