Key takeaways
Dysport (abobotulinumtoxinA) and Botox (onabotulinumtoxinA) are both neuromuscular blockers made from the botulism toxin and are used to treat various conditions by relaxing muscles. Dysport is primarily used for muscle spasms in the neck and limbs, and for frown lines in adults under 65. Botox, on the other hand, has a broader range of uses, including treating overactive bladder, preventing migraines, reducing excessive armpit sweating, and more. While both medications are injected by a healthcare provider, Botox is only available as a brand, which might make it more expensive, whereas Dysport does not have a generic form either. Dysport's effects typically last 3 to 5 months, while Botox's duration can vary depending on the condition being treated. Both medications can cause serious side effects if the toxin spreads beyond the injection site, but Botox has additional risks like urinary tract infections and trouble urinating when used for bladder issues.
