Which regimen is an appropriate treatment for erysipelas?

• A. Penicillin V
• B. Ceftriaxone IM + penicillin PO
• C. Augmentin
• D. Erythromycin

Answer: (B)

Erysipelas is typically caused by beta-hemolytic streptococci, and controlling the infection quickly is important, especially when the disease is more extensive or the patient needs to be treated as an outpatient. Using ceftriaxone given by intramuscular injection provides reliable, rapid parenteral antibiotic levels that help blunt the infection promptly. Following that with oral penicillin completes the course with continued anti-streptococcal coverage, while allowing easier outpatient management and a full, appropriately timed duration of therapy. Penicillin V alone is often sufficient for very mild disease, but may be slower to control or insufficient when a rapid response is needed. Broader or alternative regimens like Augmentin or erythromycin add unnecessary spectrum or have other downsides (resistance, side effects) for a straightforward streptococcal erysipelas.
