*Patients were defined as treatment–naïve if at least 12 months had passed since their last botulinum toxin treatment for blepharospasm.
†XEOMIN 25 Units was not statistically significant when compared with placebo at Week 6 (P=0.1452)1,2

In patients previously treated with Botox®

XEOMIN Was Proven Noninferior to Botox

  • XEOMIN and Botox were similarly effective in treating blepharospasm as measured by the JRS sum score at Week 34

The potency Units of XEOMIN are specific to the preparation and assay method utilized. They are not interchangeable with the other preparations of botulinum toxin products and, therefore, Units of biological activity of XEOMIN cannot be compared to or converted into Units of any other botulinum toxin products assessed with any other specific assay method.

XEOMIN and Botox Had Similar Onset, Waning, and Duration of Effect5

Onset, waning, and duration of effect between XEOMIN® and Botox. Pinch to zoom

‖Patient–reported outcome: onset and waning of effect were subjectively estimated by the patient at control and end of study visits.
¶Duration of effect was calculated based on the time between the initial injection and the end of study visit (when the subject and the investigator agreed that a new injection was needed).

The duration of effect in patients with blepharospasm
was comparable between XEOMIN and Botox.4
