My Mother is very susceptible to hallucinations, also. Her "miracle" has been in the drug, Seroquel. It has not only entirely stopped any hallucinations but has also helped "stretch" the effects of Sinemet. Discuss Seroquel with your Mother's Neuro and good luck. :o) Sharon Starr, Daughter and CG for Rae 75/50/45 (age now/age dx/age first symptoms) Florence, AZ [log in to unmask] **************************************************************** my 83 year old mother has had pd 10 years and uses sinemet .
