Studies demonstrated that for prophylaxis against
postoperative wound infection, administering antibiotics during only one day after the
operation has been equally effective as a two day or longer antibiotic prophylactic
regime.
For occasions later on, when you need antibiotic protection
during dental surgery and like, usually one dose of antibiotics before the dental and
other surgery is sufficient. Ask your surgeon for detailed instructions.
There are also risks connected with the use of antibiotics.
One is the development of antibiotic-resistant bacterial strains, another is the
development of an allergy to antibiotics.
You can diminish these risks yourself: use the antibiotics
only when really necessary, and then use them only during the shortest interval possible.
