Dear Dr. van der Linden, Thanks very much for posting your info on Botox injection for halting excess drooling.Would you please explain the mechanism which results in stopping excessive drooling in a PWP?Also,how does this affect the swallowing and digestive processes.I have read that the excessive drooling is attributable to poor swallowing.Does a PWP produce more saliva than a normal person? Last week,we tried a Scopoderm patch as a means of curbing the excessive drooling. It was a disaster.Aliza started to hallucinate,her balance deteriorated, and she became very fatigued.I would be interested if other PWPs have had similar experiences with this anti-cholinergic patch. I have consulted with Aliza's neurologist Dr. Tanya Gurevich of Movement Disorders Section the Tel Aviv Medical Center re the Botox injection.They know about the procedure,but have no specific experience with it. Thanks for your help.

Infiltration using a small needle with botulinum toxin (Botox) into the parotid gland on both sides almost eliminates the excessive drooling. So far I have treated three patients with this problem and two did not have drooling anymore and one had great improvement. It is reversible and injections need to be carried out around three to four times a year. It is not painful and no side effects. It saves a lot of money on the excessive laundry of shirts and ties.
