Benzathine Penicillin

Benzathine penicillin G is the gold standard treatment for syphilis. It is given as a long-acting intramuscular injection, which provides sustained drug levels to clear Treponema pallidum. A single 2.4 million unit dose is used for early syphilis, while later stages require weekly injections for three weeks. It is also the only proven treatment for preventing congenital syphilis in pregnancy. Side effects are uncommon but may include injection site pain or a temporary Jarisch–Herxheimer reaction after dosing.

Benzathine penicillin G is the gold standard treatment for syphilis because it’s highly effective and provides long-lasting antibiotic levels. For early syphilis, it’s a single IM injection, which makes it much easier for patients to complete treatment and improves compliance. Later-stage disease requires weekly injections for three weeks, while neurosyphilis needs IV penicillin instead. It’s also the only treatment proven to prevent congenital syphilis in pregnancy, making it especially important in that setting.
