Yes, I had temporary kidney damage from the use of lithium. Fortunately, my kidneys
calmed down about a month after the lithium was removed, but there is still medium damage.

Lithium causes closure of the tiny arteries of the kidneys and there's nothing nephrologists can do about that. Your husband is very, very fortunate. I will never take lithium again with the approval of my nephrologist. My endocrinologist told me that lithium is one of the most toxic
medications on the market.

I don't speak about this often, but you did ask.
