The Power of Penicillin

Penicillin G, particularly in its benzathine form, is the first-line treatment for syphilis, effective at all stages of the disease. Its ability to maintain prolonged serum levels makes it ideal for eradicating the slow-growing Treponema pallidum bacterium. This tried-and-true antibiotic has a long history of clinical success.

What About Penicillin Allergies?

For patients allergic to penicillin, options include allergy testing and desensitization to allow safe use of the drug. If these aren't feasible, alternatives such as doxycycline or ceftriaxone may be considered, although they may not be as effective as penicillin.

Alternatives and Their Efficacy
