I am scheduled to start Martazapine tonight. I have seen it written up in a couple of publications lately - suggesting it was working to control the tremor in PD. My neurologist is inexperienced with it, but willing to give it a try. I will start slowly (one pill/night for three or four nights), then call the doctor and decide from there. I am eager to hear from the others on this list who are trying it. Someone suggested it causes neutropenia. This sounds pretty awful! Do you know if that is reversible? That can mean a number of threatening problems: leukemia, rheumatoid arthritis, etc. Aloha, Joan Dykstra
