Which antibiotic is listed as used to treat osteomyelitis in the material?

• A. Amoxicillin
• B. Clindamycin
• C. Ampicillin
• D. Penicillin VK

Answer: (D)

Penicillin VK is effective for osteomyelitis because bone infections arising from dental sources are typically caused by streptococci and anaerobic bacteria found in the oral flora, and this antibiotic has reliable activity against those organisms. It’s a narrow-spectrum penicillin with good oral absorption, allowing adequate bone concentrations to help clear infection. In the material you’re studying, this antibiotic is listed as used to treat osteomyelitis, which is why it’s the best choice among the options. If a patient cannot take penicillin, clindamycin is a common alternative because it covers similar anaerobic and streptococcal pathogens. While amoxicillin or ampicillin can also be used for odontogenic infections, the material specifically highlights Penicillin VK for osteomyelitis.
