What penicillin dosage is recommended for open fractures at a farm due to possible Clostridium contamination?

• A. 1-2 million units
• B. 100-200 thousand units
• C. 10-20 million units
• D. 50-100 thousand units

Answer: (C)

High-dose penicillin G is used when an open fracture is contaminated and clostridial infection is a concern, because Clostridium species are anaerobic and can cause rapid, life‑threatening tissue infection. To effectively suppress these bacteria and their toxin production, penicillin G must be given in very large amounts, typically totaling tens of millions of units per day in divided doses. This makes the option in the tens of millions of units per day the best fit among the choices. Lower doses would not achieve the necessary tissue concentrations to control clostridial infection. The management would also include prompt surgical debridement and consideration of adjunctive therapies as needed.
