Not really: Some antibiotics can prevent some STDs, but to prevent all common bacterial STDs would require at least 2 or even 3 different drugs. Even these would not prevent the 2 most common STDs, herpes and HPV. And taking multiple antibiotics brings a whole bunch of health problems. Therefore STD prevention relies on wise partner choice, safe sex, and early diagnosis & treatment, not prior antibiotics.
