Hi there. I’m brand new here and I was looking for Parkinson’s related information and found your post. I take 100mg 3x a day of Amantadine and 1mg of Pramipexole 3x also. These drugs help my tremors. I have also found that it was developed a long time ago as an antiviral and that currently there are studies showing it may have an effect on Covid-19. Any how I haven’t noticed a side effect yet for me
