Throat gonorrhea (pharyngeal gonorrhea) is an infection of the throat with the bacterium Neisseria gonorrhoeae, usually picked up through oral sex. Most throat infections cause no symptoms at all, so testing the throat matters. A single antibiotic injection cures it, but it's harder to clear than genital gonorrhea.

The essentials
Gonorrhea is caused by Neisseria gonorrhoeae, a bacterium that can colonize the genitals, the rectum, and the throat CDC. When it sets up in the pharynx — the back of the throat and tonsils — it's called pharyngeal gonorrhea. You get it through oral contact with an infected penis, vagina, or anus. For the exact routes, see can you get gonorrhea from oral sex or kissing?.
Two things make the throat a special case. Most pharyngeal infections are silent: no sore throat, no warning, nothing to prompt you to test. And the throat is a tough environment to cure. Even fully susceptible pharyngeal infections fail standard treatment a small but real fraction of the time, so guidance treats the throat differently from the genitals.
The pharynx is full of harmless Neisseria species, and gonorrhea can swap resistance genes with these neighbors, making the throat a breeding ground for drug-resistant strains CDC. Untreated pharyngeal infection is usually symptomless and can persist for up to 16 weeks, so it sits quietly and spreads, both as a transmission source and as an incubator for resistance.
Antibiotics cure gonorrhea. What they can't do is reverse damage already done elsewhere in the body, so catching it early still matters.
Symptoms of throat gonorrhea
Most throat infections produce no symptoms. The CDC describes the majority of gonococcal infections of the pharynx as asymptomatic CDC, 2021 guidelines. You can carry it, pass it on, and never know without a test. When symptoms do appear, they're nonspecific and easy to write off as a routine cold:
- A sore or scratchy throat that doesn't seem to follow a cold.
- Redness in the throat or some difficulty swallowing.
- Occasionally swollen lymph nodes in the neck.
Because these overlap with strep, viral pharyngitis, and post-nasal drip, you can't diagnose throat gonorrhea by how it feels. Your sexual history is the reliable signal. If you've given oral sex to a partner whose status you don't know, the throat should be tested whether or not anything hurts.
Genital and rectal infections have clearer (though still often absent) signs. In men, gonorrhea can cause burning on urination and a white, yellow, or green discharge from the penis; less commonly, swollen or painful testicles. In women, it's commonly asymptomatic, but it can cause painful urination, increased vaginal discharge, or bleeding between periods. Rectal infection can bring discharge, anal itching, soreness, bleeding, or painful bowel movements. None of these are throat symptoms, but people are frequently infected at more than one site at once.
How throat gonorrhea is tested
A nucleic acid amplification test (NAAT) is the preferred test for gonorrhea, with sensitivity usually above 90% and specificity around 99%. For the throat, that means a quick swab of the back of the throat and tonsils, sent for the same molecular test used at other sites.
A urine test does not detect a throat infection. NAAT only finds gonorrhea where the sample comes from, so if you've had oral sex, you need a pharyngeal swab specifically. Screen every anatomic site of sexual exposure: urine or a vaginal swab for the genitals, a rectal swab if you've had receptive anal sex, a throat swab if you've given oral. Patient-collected swabs are acceptable at many clinics, which makes this less awkward than it sounds.
Testing is a first-catch urine cup plus a fast throat or rectal swab if relevant, the whole thing taking minutes. The most common and costly mistake is not asking for the throat swab. If you only give urine, a throat infection is missed entirely, and you walk out thinking you're clear. Ask for every exposed site by name. Timing matters too; tests can be falsely negative too soon after exposure, so check when to test after exposure before you book, and you can get tested at a clinic or by mail.
Treatment for throat gonorrhea
First-line treatment is a single intramuscular injection of ceftriaxone, 500 mg, for people under 150 kg; people who weigh 150 kg or more get 1 g MMWR, 2020. This one shot covers genital, rectal, and throat infection. If chlamydia hasn't been ruled out, doctors add doxycycline, 100 mg by mouth twice daily for 7 days, since the two infections often travel together.
Treatment changed in 2020. It moved from dual therapy (ceftriaxone plus azithromycin) to ceftriaxone alone, and the ceftriaxone dose was raised from 250 mg to 500 mg. Azithromycin was dropped because resistance to it climbed fast — isolates with elevated azithromycin MICs rose from 0.6% in 2013 to 4.6% in 2018 — and over concerns about disrupting the gut microbiome and driving further resistance. N. gonorrhoeae remains highly susceptible to ceftriaxone, so it now stands as the lone first-line drug. The full background on dosing and the shift to a single injection lives in our gonorrhea treatment guide.
The throat needs extra caution. Pharyngeal infections are harder to eradicate than urogenital or rectal ones; even susceptible throat infections failed ceftriaxone about 4.6% of the time treatment-failure review. So a test-of-cure is advised for the throat: return 7–14 days after treatment for a repeat test (culture is preferred where available, otherwise NAAT). This step isn't routine for genital infection; it's specific to the throat's stubbornness.
If you have a cephalosporin allergy, the alternative is gentamicin, 240 mg IM, plus azithromycin, 2 g by mouth, both as single doses. If ceftriaxone simply isn't available, cefixime, 800 mg orally as a single dose, is an option, but cefixime reliably treats only urogenital and anorectal gonorrhea. It does not dependably cure the throat, so a test-of-cure is mandatory after cefixime for any pharyngeal infection.
In practice, the shot is given on-site at the clinic. There's no take-home pill for the gonorrhea itself, because oral antibiotics are no longer reliable as first-line care. It's free or low-cost at public clinics. After the injection, abstain from sex for 7 days. Partners from the prior 60 days need testing and treatment, and you should retest about 3 months later because reinfection is common.
Why resistance makes the throat the front line
Gonorrhea has burned through one drug class after another — sulfonamides, penicillin, tetracyclines, fluoroquinolones, and cefixime — leaving cephalosporins described as essentially one last reliable class WHO. Ceftriaxone-resistant strains are no longer theoretical: the FC428 strain emerged in Japan in 2015 and has since spread internationally, and the WHO estimated 82 million new gonorrhea infections worldwide in 2020. No verified US clinical ceftriaxone treatment failures have been reported to date, but susceptibility is slowly decreasing. The CDC tracks this through resistance surveillance programs. You can read more on what a resistant infection means for care in our gonorrhea treatment resource.
Preventing throat gonorrhea
The methods that work are unglamorous but effective:
- Use condoms or dental dams correctly every time, including for oral sex.
- Get screened regularly at every exposed site, and ask specifically for the throat swab.
- Treat partners and abstain from sex for 7 days after treatment so you don't pass it back and forth.
- Mutual monogamy with a tested partner lowers risk; abstinence is the only certain method.
A note on DoxyPEP (doxycycline taken within 72 hours of sex): it cuts chlamydia and syphilis by more than 70%, but it's far less effective against gonorrhea — around 50% in one trial, with inconsistent results across studies CDC, 2024. The CDC does not recommend DoxyPEP for gonorrhea prevention specifically, partly out of concern it could drive tetracycline resistance in N. gonorrhoeae. Don't rely on it for the throat.
Quick comparison: throat vs. genital gonorrhea
| Throat (pharyngeal) | Genital (urogenital) | |
|---|---|---|
| Usual symptoms | Most often none; sometimes mild sore throat | Often none; possible discharge, burning urination |
| Test needed | Throat swab (urine won't detect it) | First-catch urine or vaginal swab |
| First-line treatment | Single ceftriaxone injection | Single ceftriaxone injection |
| Cefixime backup works? | No — not reliable for the throat | Yes |
| Test-of-cure? | Yes — 7–14 days after treatment | Not routine |
| Harder to cure? | Yes | No |
When to see a clinician
See a clinician if you've had oral, vaginal, or anal sex with a partner whose status you don't know, even with no symptoms, because the throat usually stays silent. Get checked promptly if a partner tests positive, or if you have a sore throat that persists alongside any genital or rectal symptoms.
Don't wait on a swollen, painful testicle. That can signal epididymitis (inflammation of the coiled tube behind the testicle that stores and carries sperm), which can threaten fertility if it's not treated quickly. See someone that week.
Reported gonorrhea has actually been falling — about 601,000 cases in the US in 2023, down from the recent peak CDC AtlasPlus, 2023. Rates vary enormously by location, so your local risk depends a lot on where you live and your number of partners.
