How are Botulinum Toxins Used?
Botox® was approved by the U.S. Food and Drug Administration in 1989 for the treatment of strabismus (lazy eye) and blepharospasm (uncontrolled eye blinking).
Since that time it has also been approved for cervical dystonia (torticollis), facial wrinkles, migraine, excessive sweating, spasticity, and bladder spasms.
Myobloc® was approved for cervical dystonia only in 2000.
Dysport® was approved in 2009 for cervical dystonia and facial wrinkles.
Xeomin® was approved in 2010 for cervical dystonia and blepharospasm.
