Or are they saying that it will continue to be of some benefit for many years, from early stages to late stages. I am taking it now as my only PD med, is it some help, but not a lot. I have tremor as only symptom. Anyone have any clue? >> Maybe this is what you want to know: My Amantadine has continued t o exert its anti-Parkinson effect for about 15 years now. While it is weaker than other drugs, I miss it as soon as I stop it. However, the powers that be in the physician community have only recently discovered its anti-dyskinesia effects as significant.
