Lip wounds require antibiotics under which circumstance?

Lip wounds require antibiotics under which circumstance?

• A. Contaminated or through and through (PCN or clindamycin)
• B. Always give antibiotics for all lip wounds
• C. Never require antibiotics
• D. Only if fever present

Answer: (A)

In lip wounds, the main factor guiding antibiotic use is the level of contamination and whether the wound breaches the lip into the oral cavity. The mouth harbors a mix of aerobes and anaerobes, so wounds that are contaminated or that traverse the lip into the oral mucosa have a higher risk of infection. In these cases, prophylactic antibiotics are appropriate to cover the oral flora. First-line options include penicillin (PCN) or amoxicillin; if penicillin allergy is present, clindamycin is a good alternative. Fever or other signs aren’t required before starting antibiotics, and clean, uncomplicated lip wounds may not need them.
