What is the primary treatment option for primary, secondary, and early tertiary syphilis?

• A. Benzathine penicillin G 1.04 million units IM in one dose
• B. Azithromycin 1 g orally in one dose
• C. Doxycycline 100 mg orally twice daily for 1 week
• D. Benzathine penicillin G 2.4 million units IM weekly for three weeks

Answer: (A)

Benzathine penicillin G 1.04 million units administered intramuscularly in a single dose is the primary treatment option for primary, secondary, and early tertiary syphilis. This recommendation is supported by extensive clinical guidelines and research, indicating that benzathine penicillin G is highly effective in eradicating Treponema pallidum, the bacterium responsible for syphilis.

Administering this specific dosage allows for adequate drug levels to remain in the body to combat the infection effectively. This treatment is recognized for its efficacy, safety, and cost-effectiveness, making it the first-line therapy for the earlier stages of syphilis.

Other treatment options such as azithromycin and doxycycline are generally considered alternative choices, usually indicated in cases of penicillin allergy or specific clinical scenarios. However, they do not have the same level of endorsement as benzathine penicillin G in treating syphilis effectively across all its early stages. Benzathine penicillin G, therefore, stands out as the most reliable and widely accepted treatment option for these stages of syphilis.
