The potency Units of Dysport Cosmetic (ababotulinumtoxinA) for injection are specific to the preparation and assay method utilized. They are not interchangeable with other preparations of botulinum toxin products and, therefore, units of biological activity of Dysport cannot be compared to nor converted into units of any other botulinum toxin products assessed with any other specific assay method.
Indication specific dosage and administration recommendations should be followed.
In treating adult patients for one or more indications with Dysport, the maximum cumulative dose should generally not exceed 400 Units, in a 3-month interval.
The safety and effectiveness of dosing with Dysport more frequently than every 3 months have not been clinically evaluated.
The safe and effective use of Dysport depends upon proper storage of the product, selection of the correct dose, and proper reconstitution and administration techniques. Physicians administering Dysport must understand the relevant neuromuscular and structural anatomy of the area involved and any alterations to the anatomy due to prior surgical procedures and disease.
Contraindications
DYSPORT is contraindicated in patients with known hypersensitivity to any botulinum toxin products, cow’s milk protein, or to any of the components in the formulation, or infection at the proposed injection site(s).
