Abx can cause anxiety....

That is quite a long thread on this subject.

With some people, antibiotic anxiety can be directly related to your livers ability to detox without the liver enzymes becoming elevated. Elevated enzymes = toxic liver.

A "toxic liver" directly offsets other body chemical compositions, some amino acids which are part of nuero transmitter pathways. Its all connected. Create a block, or speed one up, and this can create problems based on if you have any natural pathways issues/mutations or not. A Drs showed this to me on a liver detox pathway map. I dont remember the details. They can be goggled.

Lots of possibilities.

Is a toxic liver created from just ABX, the dead stuff from taking abx, or both, that is the question...?

Remember it kills all bacteria, so the potential to temporarily create a toxic liver exists with killing bad bugs as well as the good bugs in you.

My LLND advised me that Biaxin caused anxiety. It can also cause heart palpitations. He wanted me to be aware so I could monitor.

In my case, the anxiety came before the medications, and resolved with treatment...so it depends i guess.
