Meet Peter
“Hi, I’m Peter. I’m 55 years old and have been living with Parkinson’s Disease for five years.
I work part-time as a shop assistant and in my free time I enjoy playing the piano in a little music group with my friends, and I enjoy spending time with my grandchildren.
I sometimes get OFF episodes when my Parkinson’s medication does not control my condition well enough.
My doctor has prescribed Inbrija® to help with those OFF episodes.
Be sure to read the documents on this site, especially the Patient Information Leaflet”
