What should be done if a syphilis patient does not use penicillin aggressively?

Patient's question:

Toxicity ratio 1:16

Doctor's answer:

Hello, the treatment for syphilis is primarily based on Western medicine, commonly using drugs such as penicillin, doxycycline, and tetracycline. For those allergic to penicillin, erythromycin can be used as an alternative. It is recommended that you persist in treatment until fully recovered and pay attention to hygiene in daily life.
