Hi I am new to this. I got interested in trying Kava because I have chronic pain due to CRPS (complex regional pain syndrome) and I heard in my support group that some people were getting relief with Kava, so I wanted to try. However, I am on several other medications. I did a google search to check for drug interactions and came up with this site: https://www.rxlist.com/kava/supplements.htm#Interactions and on this site I see that 4 of my meds interact! (Amitriptyline, Topomax, Allegra, Xyzal) I don't even know how to check the other herbs and supplements I take... But it got me wondering about how this list was generated in the first place and if it is really legit. It seems that they have every possible medication listed because they are assuming kava is generally toxic to the liver and of course all meds have to be processed through the liver. Can someone help clarify this for me? I thought that this was not true these days if you bought from a good vendor. Are the specifics of how kava is processed in the liver known so we can get more specific drug interaction information?
