How to control drooling when you are a stage 4 Parkinson's?

there are a couple of drugs for this- to dry it out - if you are any chance on Hospice care -(or perhaps the primary or neuro ) there are several they can discuss with you. plus the patch cwillie mentioned may be helpful. You will just have to weigh the side effects....
When you say stage 4- which is where my mother is- Im assuming you are unable to even consider the botox at this point,
The saliva thing/swallowing/drooling/phleghm is all part of the Parkinsons disease. as is the side effect from the sinemet. Kind of a double edge sword- just went through aspiration and pneumonia from this whole swallowing issue, Using thickeners for water and day by day here. Hope you can get something that works.
In the meantime, prop those pillows up when he is lying down and if the drool is not thin- more mucousy then see about using a guafenessian cough syrup (no dm) to thin it out so he can get it out. Also pay extra attention during this time to dental care.

Talk to Dr about adjusting meds, my husband drools when his levels of carbidopa-levodopa are too high. We cut back # of doses per day and the drooling stopped.

Even though threads have been closed to new comments you should still be able to read everything others have written there😕? Of course you should be working with his doctors but some suggestions I have read are:

chewing gum or sucking a lollipop can help to stimulate swallowing

transdermal scopolamine skin patches

botox injections
