Dysport® comprises of abobotulinum toxin A and Botox® comprise of onabotulinum toxin A, a toxin that is derived from the Clostridium botulinum bacteria.

Dysport® is often used to manage cervical dystonia which is characterised by abnormal tone in the muscles of the neck which results in an abnormal head position.
This application also hold good for Botox® as well. In addition, both of these drugs are useful in treating fine lines and wrinkles.

At the end of the day, patient preference and cost will eventually drive which of the two will be used by the physician.
