Cervical Dystonia

Dosing of Botulinum Toxin Type B

It is important that patients discuss previous treatments for cervical dystonia, particularly injections with other serotypes of botulinum toxin, such a botulinum toxin type A (BOTOX or Dysport). Patients are urged to share copies of their medical records so that their treating physicians are able to determine previous drug and chemodenervation agents and the doses given. Since the dosing for botulinum toxin type B product is different from that of botulinum toxin type A products, and indeed between different products of the same serotype, physicians will make the appropriate adjustment in the number of units required for treatment with botulinum toxin type B. One method for accessing a patient's response to treatment is use of the TWSTRS rating scale.
