Perhaps only if there is an allergic reaction. Allergic reactions set off histamine and inflammatory cytokines which attack tissues in the body. So that is always possible that PN would be one form of damage.

However all antibiotics are capable of damaging mitochondria to some extent research is finding. Cephalosporins work on bacteria in a way similar to amoxicillin, and amox has been implicated in mito damage in autistic children. Not proven yet, but implicated.
