The U.S. Food and Drug Administration (FDA) has not yet approved their use for any specific pain disorders, although two forms of BTX (A and B) have been approved by the FDA for other medical conditions associated with pain and discomfort. However, BTX continues to be used successfully by a range of specialists to address pain control.
