Hello Dollydream.. Welcome to TP. I have just Googled this medication because it's not one I have heard of, however I have heard of it's other name....Memantine and although I cannot give you any information I thought that, by showing it's other name, others will be able to help. Tp is usually full of useful information
Perhaps if you can give us a little background of the person you are caring and their illness someone will be able to give you more assistance.
Look forward to hearing from you soon.
