As I have mentioned before a new treatment for drooling in PD exists. Since several months I inject with a small needle botulinum toxin in the parotid glands, which inhibits the release of saliva; it will give you a dry mouth, but it surely works in my patients. Not painful and no side effects. Off course you have to seek the advice of a movement disorder specialist. It is quite a new treatment so many doctors will not have heard about it yet. Botulinum toxin is manufactured by Allergan, Inc USA. Good luck and best regards, Chris van der Linden St. Lucas Hospital Ghent Movement Disorder Center Ghent BELGIUM
