Edith has tremor=type PD and began amantadine 100mg twice daily - almost after 24 hours she suffered side effects (nausea, depression, fatigue). She stopped the drug and recovered after several days. Then re-started amantadine LIQUID (50 MG/TSP) - 1/2 tsp and gradually (over several weeks) built up the dose to her present level without adverse incident. She now takes 100mg capsule twice daily plus Eldepryl 5 mg daily. It has been of moderate help for her tremor. Ralph
