I am 50 years old and have been diagnosed for 3 years In cutting down from 200mg to 100 mg per day I am experiencing constant tremor >> Hi Frank, Symmetrel or Amantadine is one of the PD drugs I have been on for 6 years. You should try to get in touch with your neuro and tell him or her what is happening. Symmetrel is one drug you should not stop taking cold turkey. I started on Mirapex when my tremor became more noticeable. Here is the url of a very good site for PD drugs information. http://www.ionet.net/~jcott/homepage/drugdb/drugdb.html Best to you Dennis 58/52
