Dysport Vs. Botox

Although Botox® (onabotulinumtoxinA) and Dysport® (abobotulinumtoxinA) are different medications, they have many similarities. For example, both products are approved to:
  • Temporarily improve the appearance of wrinkles between the eyebrows (frown lines)
  • Relieve neck pain and abnormal head position associated with cervical dystonia (a certain kind of muscle spasm of the head and neck).
However, Botox is licensed for additional uses, including the treatment of:
  • Severe underarm sweating that has not responded to other treatments
  • Eyelid twitching or spasms (known medically as blepharospasm)
  • Misaligned eyes, such as crossed eyes (known medically as strabismus).
Both medications are a toxin produced by Clostridium botulinum bacteria. They work by decreasing nerve signals to muscles, which helps the muscles relax. In addition, both medicines are available by prescription only, and neither one is available as a generic.
Dysport comes in the following vial sizes:
  • Dysport 300 unit single-use vials
  • Dysport 500 unit single-use vials.
Botox comes in the following vial sizes:
  • Botox 50 unit single-use vials
  • Botox 100 unit single-use vials.
