Botulinum Toxin Type A Dosing

Botulinum toxin type A dosing guidelines take into account how a person responds to the drug, the condition being treated, and other medical conditions that are present. The drug comes in injectable form, and special techniques are often used to ensure that it is administered to the correct site. You will need to receive repeat doses of botulinum toxin type A to maintain the desired results.

An Introduction to Botulinum Toxin Type A Dosing

In 2009, the generic name for Botox was changed from "botulinum toxin type A" to "onabotulinumtoxinA." This was done to prevent confusion between Botox® and Dysport® (abobotulinumtoxinA), a new botulinum toxin type A product.

The dose of botulinum toxin type A (Botox®) that your healthcare provider recommends will vary depending on a number of factors, including:
  • The condition being treated
  • How you respond to botulinum toxin type A
  • Other medical conditions you may have
  • Other medications you may be currently taking.
As always, do not adjust your botulinum toxin type A dose unless your healthcare provider specifically instructs you to do so.
