A member asked:
If i was exposed to syphilis from kissing, how long does it take for me to become contagious by kissing someone else? should i take doxypep for this exposure?

If your kissing partner has documented chancre or other proved syphilitic lesion of the mouth, this would be sufficiently high risk to warrant doxy-PEP. Otherwise probably not. Doxy-PEP has only been studied in relation to anal sex in MSM, not kissing.
