I remember sometime back that there was a discussion of Namenda helping to lower doses of other pain medications. Then we saw an article in an RSD newsletter about Namenda helping to reduce the amount of methadone the person needed. Does anyone have any current information on that? We have asked my husband's PM doctor about it and he is willing to look into it, but has not heard about it. It would be great if he could eliminate some of the side effects of the methadone. Does Namenda have its own side effects that we should be careful of? My husband is also on Lyrica, Wellbutrin, Cymbalta, Catapres, and Zanaflex.
