Hi Laurie,
I trialed Namenda several months ago. Unfortunately it didn't work for me. There is more to the story in my case however...
I have a condition called Dystonia that is a movement disorder caused by a problem in a specific part of the brain called the basal ganglia. As a result, Dystonia reacts quite badly to particular meds that work within the brain. Namenda is one of them. Because of side effects due to my Dystonia, I really wasn't able to trial the Namenda as we had hoped. I tried it three times, praying we could figure out a way to make it work. The drug information didn't at that point mention the problem, so it caught me quite off guard.
That said, when I had a discussion with my headache specialist, she mentioned that Namenda has a really good side effect profile, and is especially good with Migraine with aura. We really thought it was worth trying. Many docs are catching on and giving it a go with their patients, and many are successful.
I hope you have luck with Namenda. Remember that a first try may result in some side effects that a second, slower try may make easier for you. So many patients give up so quickly, when often it is just an alteration in HOW the trial is done that turns a miserable failure into a life changing success.
Good luck hon!
