Quick Answer

Gonorrhea is curable with a single injection of ceftriaxone, with doxycycline 100 mg twice daily for 7 days added if chlamydia has not been ruled out. Antibiotics kill the bacteria, but resistance is rising, so follow-up testing is essential. Metronidazole (Flagyl) does not treat gonorrhea.

  • Gonorrhea is caused by bacteria and is curable with antibiotics.
  • The recommended treatment is a single intramuscular injection of ceftriaxone 500 mg, with doxycycline 100 mg twice daily for 7 days added if chlamydia has not been ruled out.
  • Antibiotic resistance is a growing concern, so follow-up testing is essential.
  • Metronidazole (Flagyl) does not cure gonorrhea and is not part of standard treatment.
  • Retesting 2 weeks after treatment is recommended to confirm the infection is gone.

The Landscape

Gonorrhea is a bacterial infection caused by Neisseria gonorrhoeae. Because it is bacterial, antibiotics can eliminate it completely—unlike viral infections that are managed rather than cured. However, the bacteria have become increasingly resistant to many older drugs. Current guidelines recommend a single intramuscular injection of ceftriaxone, with doxycycline 100 mg twice daily for 7 days added if chlamydia has not been ruled out or doxycycline, to ensure the infection is cleared. Treatment works by stopping the bacteria from building cell walls, leading to their death. Even after successful treatment, you can get gonorrhea again if exposed.

Treatment Windows by Infection

Bacterial infections clear with antibiotics measured in days: a single 500 mg intramuscular ceftriaxone dose for gonorrhea (doxycycline is added only if chlamydia has not been ruled out), seven days of doxycycline for chlamydia, penicillin injections for syphilis staged by duration. Viral infections play a longer game — suppressive antivirals for herpes, daily ART driving HIV to undetectable, and 8–12-week antiviral courses curing over 95% of hepatitis C cases.
