I would still be careful about B6 toxicity. I would advise testing before taking and then testing again a few months after taking to watch levels.

My doctors put me on B6 right away without testing and my levels shot up through the roof, probably worsening my PN. I would have kept taking the B6 if I hadn't listened to my own gut feeling and make them test me (after asking many times) and getting my test results myself to check (they never noticed this, even after they received the lab results back - I had to point it out to them).

It is a good idea to keep an eye on your levels because your body might not be eliminating it as expected.

I have now been off it for four months and my body is still not back to normal levels.
