I'm on doxycycline and I just pierced my ears… will the doxycycline prevent the piercing from infection?
I wіll dеfіnіtеlу keep thе piercings сlеаn anyway (four prior piercings аnd I don’t want thіѕ one tο bе thе one thаt becomes infected), bυt I wаѕ јυѕt wondering out οf curiosity ѕіnсе I hаνе tο take thе doxycycline anyway fοr something unrelated… wіll іt prevent infection ѕіnсе іt’s аn antibiotic? οr dοеѕ thаt nοt matter?
οn doxy fοr a skin condition (hidradenitis suppurativa — kinda cystic acne type thing οn mу thighs)


Not necessarily. Doxycycline is an antibiotic effective in treatment some types of infections depending on the bacteria that causes the infection. It’s also used for a couple of other – non infectious reasons as well.
Each antibiotic effects only certain bacteria. There are lots of bacteria that Doxycycline does not work against. The only way to be sure is to have a culture and sensitivity done of an actual infection. The culture will tell the microbiologist what bacteria(s) are present and the sensitivity will tell what antibiotics the bacteria is sensitive to.
Your best bet is to do as you planned and keep the area very clean and care for it as directed by the person who did the piercing (I’m thinking you went to a professional).
Also, FYI, there is a very dangerous bacteria popping up in the community that was previously only found in hospitals – it is called methicillin resistant staphylococcus aureus (MRSA). That one can be deadly and very resistant to treatment.
What are you on the Doxycycline for, first of all?
