More on dextromethorphan:

There is a new drug out there being offered for pain management, and it contains DM + quinidine to slow the metabolism of the DM...so it might be more effective. It is just being offered in some pain management programs.
Here is a link about it....

Also DM is in the news for MS, and PD as well. Here is a link to that discussion:

I also posted years ago about my response to DM and my feet, back when they were burning up a storm:

DM is a NMDA pain receptor blocker, and is weak in this action, but does work on glutamate actions. This pain receptor is also blocked by magnesium. So attention to that is important.

I know Nide44 tried it long ago with is doctor's supervision, but felt it wasn't working for him. High doses were used.

Now it seems that low doses, may work in a different way. It is something to think about. At high doses, there are side effects.
Sometimes I get dizzy with it for example. I crack the Mucus relief in half (it is not coated or delayed release) and it still seems to work for me, without the dizziness. The PD posters here have discussed low dose DM for quite a while. If you search there, using "dextromethorphan" you'll find many posts.
So even in small amounts it does seem to affect the nervous system.
