Syphilis can be cured, and the cure effect is related to the stage of syphilis. Stage I syphilis and stage II syphilis can be clinically cured in the majority of patients as long as they are detected early and receive timely standardized treatment. If syphilis is detected late and has developed to stage III syphilis, with manifestations of meningitis syphilis, neurosyphilis, cardiovascular syphilis, etc., the syphilis spirochetes in the blood can be cleared by standardized anti-syphilis treatment, which may leave serious complications such as paralytic dementia, aortic aneurysm, aortitis, etc., and cannot be completely cured. The most important drug for syphilis treatment is penicillin. The syphilis spirochetes have very low resistance to penicillin, and the syphilis spirochetes in the serum will be eliminated after regular, adequate and full course of treatment. If you are allergic to penicillin, you can use tetracycline or erythromycin. Once you notice that you may have syphilis, you must go to the hospital in time.
