Costs of Treating Dystonias and Hemifacial Spasm with Botulinum Toxin A

Botulinum toxin (BTX) has become a safe and effective therapeutic tool in the treatment of a variety of neurological disorders, especially dystonias. One major disadvantage, however, is the high cost of a single injection of BTX. In this study of 835 patients, we calculated the cost of treatment with BTX serotype A (BTX-A) for different dystonias and hemifacial spasm.
