Antibiotics are given prophylactically for several indications (e.g. prior to dental surgery).
Why are the treatment periods for prophylactic antibiotics much shorter than when treating an infection?
- Example: Prophylactic antibiotics may be the day before surgery, but in the case of infection, they are often given for 10-14 days.
Is there something different about pre-infection bacteria (or the body) compared with after the infection has set in?
Looking for general concepts here, as I recognize there are many different types of bacteria and antibiotics.
