- Tetracycline 500 mg by mouth 4 times per day for 2 weeks.
- Erythromycin 500 mg by mouth 4 times per day for 2 weeks.
- Ceftriaxone 250 mg IM (intramuscular injection) daily for 10 days.
For treatment of syphilis of greater than 1 year duration :
- Benzathine penicillin 2.4 million units IM weekly for 3 weeks.
- Doxycycline 100 mg by mouth twice per day for 30 days.
- Tetracycline 500 mg by mouth twice per day for 30 days.

To treat syphilis during pregnancy: Penicillin is recommended as the only drug of choice. Tetracycline cannot be used because of toxicity to the fetus, and erythromycin may fail to prevent congenital syphilis in the fetus. Penicillin-allergic individuals should be desensitized and then treated with penicillin.
