A 52-year-old male asked:

I understand syphilis is unlikely from getting oral sex from a female. the day after,i was given a shot of rocephin and put on doxycycline 100mg twice a day for7 days as a precaution will this dose of doxy kill syphilis as well or is7 days too short?

The doxycycline doesn't matter. The standard ceftriazone (Rocephin) dose always prevents syphilis when given soon after exposure. You are 100% protected against gonorrhea, syphilis, and chlamydia. (Not that you needed such treatment after a single oral sex exposure!) That's my last comment to your third (?) question about this event. No more, please.

This is prophylactic- or 'just in case, and should be OK
