At least one study [1] finds topical doxycycline to be useless for prophylactic treatment of lyme. Do you have any evidence supporting its use?

I know my infectious disease doctor told me to take a one day oral dose as a prophylactic treatment after you pull off the tick.

That has nothing to do with its topical application. Drugs that perform well via one route are often ineffective via the other. According to the study I linked, that appears to be case here.

Right, pretty sure we agree on that one. I thought I was backing you up, suppose I should have replied to parent comment instead...

My bad, I misread it as a bit of a counterpoint.
