Does amantadine (Symmetrel) help with fatigue? I read that it does and you can take it with your MS medications, or is there an herbal med that will help with that? I have become so fatigued it is causing problems in my everyday life. Also is chlordiazepoxide (Librium) better for anxiety than klonopin?
Amantadine has been shown to be helpful in treating mild MS-related fatigue, but how it actually does that is not clear. It was originally developed as a prophylactic agent for the flu decades ago (but not really used for that anymore). Fatigue due to MS is the most reported (and disabling) feature of MS. There are many other factors that can add to fatigue (heat, sleep problems, depression, and many medications used to treat symptoms of MS including those for anxiety that you mention in your question) and should be reviewed with your doctor. Amantadine is a good place to start (for treatment of fatigue due to MS), but if it is not sufficient, there are other stimulant options that your doctor can discuss with you (modafinil, methylphenidate, etc).
I do not have an opinion regarding the relative effectiveness of different anxiety medications (it's hard to know what is best for a certain individual, and requires a trial/experience approach with a doctor who is following you closely). Hope this helps.
