Hello!
Thanks for query.
Exelon is used to treat mild to moderate
dementia caused by Alzheimer's or Parkinson's disease.It is not useful for treating other symptoms of parkinsons like bradykinesia,tremers or rigidity.
Hence it is not a good medicine for parkinsons.
Exelon has many side effects like-
-stomach pain, nausea and
vomiting, loss of appetite,
-feeling light-headed, fainting;dizziness
-confusion, agitation, extreme fear; or
-pain or burning when you urinate.
So dizziness that your wife has may be due to this medicine .
There are many safe medicines for
parkinsons disease.You can consult with physician till you get appointment of
neurologist.
Hope this helps you.
Thank you.
