Hi Moto! How ya doing lately? I'm still waiting for spring to really warm up my 5D. hehe

I tried LDN while on enbrel. At that time, I madly researched use of both concurrently, and couldn't find anything to say they shouldn't be used together. They work on totally different parts of the immune system, so theoretically, it shouldn't be a problem. I dropped LDN due to side effects (NOT due to any sort of interaction with enbrel, trust me. After being off enbrel for months, I tried LDN again with the same side effects). So, as far as I know, it's safe. Of course, perhaps we'll hear of something in the future, but as it stands, it's ok from what I've been able to dig up. I'm also guessing that if there were a really bad interaction, I'm sure we would have heard it from the people with RA taking anti-tnfs and adding LDN.
