Syphilis is a disease that has not been eradicated in part due to inadequate management of antibiotic therapy which is selected according to the stage of the disease and to the misuse of the type of penicillin. Treatment of this disease should be done to prevent it´s chronic complications, to avoid infecting sexual partners and the fetus in a pregnant woman. Syphilis in pregnancy causes increase in the rate of recurrent abortions and neonatal morbidity and mortality, that´s the main reason why early detection and treatment without delay is extremely important. Pregnancy alters immunity, so the serological diagnosis can provide false positives, with the use of inverse algorithms these results may decrease, by increasing the sensitivity of the tests. Today, after 69 years since the advent of penicillin, it has become the drug of choice for any stage of syphilis and in pregnant women; if the patient has allergy, desensitization is indicated either orally or intravenously and other antibiotic shouldn´t be used because of the security offered by penicillin in the cure rate and in the reduction of congenital syphilis.
