What is the first-line therapy for treating human bites?

• A. Doxycycline
• B. Amoxicillin/clavulanic acid
• C. Ciprofloxacin
• D. Clindamycin

Answer: (B)

The first-line therapy for treating human bites is amoxicillin/clavulanic acid. This combination antibiotic is particularly effective because it covers a broad spectrum of bacteria that are commonly associated with human bite injuries, including both the aerobic and anaerobic bacteria that can be introduced into the wound. Human bites can introduce pathogens such as Streptococcus and Staphylococcus species, as well as oral flora like Eikenella corrodens, which is often resistant to many antibiotics. Amoxicillin/clavulanic acid provides not only coverage against these organisms but also has beta-lactamase stability, meaning it remains effective against bacteria that produce enzymes to inactivate many other penicillins. Therefore, its usage is crucial in preventing infections and managing any potential complications associated with human bites. In contrast, other options may not provide the broad or effective coverage needed for the specific pathogens involved in human bites. For example, doxycycline and clindamycin may not sufficiently cover the specific anaerobes and flora typically found in human bites, while ciprofloxacin does not have reliable activity against Eikenella corrodens.
