How Gonorrhea Is Treated Today

Save

Not long ago, gonorrhea could often be treated with pills alone. That changed as the bacterium developed resistance to nearly every antibiotic class used against it, leaving injectable ceftriaxone as the one reliably effective option and the reason cephalosporins are now treated as a resource to protect rather than a routine first pick. Anyone treated for gonorrhea needs a partner treated too, or the infection simply comes back.

What Cures Gonorrhea Today

Gonorrhea is treated with an injection of the antibiotic ceftriaxone, given as a single shot rather than a pill taken at home. When a chlamydia infection hasn't been specifically ruled out, doxycycline pills are added to the regimen as well, since the two infections travel together often enough that treating for both is standard practice 1.

This combination approach — one antibiotic by injection, sometimes a second by mouth — reflects how differently the two bacteria behave under drug pressure, not a judgment that gonorrhea is somehow worse. A clinician confirms the diagnosis, checks for chlamydia and other coinfections, and administers or prescribes treatment accordingly, typically at the same visit as testing whenever that's possible.

Treatment often happens at that same visit rather than waiting for lab confirmation, since a nucleic acid test result can take days and untreated gonorrhea keeps spreading in the meantime. Site of infection also matters for follow-up: throat and rectal gonorrhea are checked, and when needed retested, using swabs from those specific locations rather than a genital sample alone.

Why an Injection Replaced Pills

Gonorrhea used to be treated with oral antibiotics alone, but Neisseria gonorrhoeae has developed resistance to nearly every antibiotic class used against it over the decades, one drug at a time 2. Cephalosporins, the class ceftriaxone belongs to, are now the last reliably effective option — which is why public-health agencies treat drug-resistant gonorrhea as an urgent threat rather than a routine concern 2.

Ceftriaxone works today, but it is being protected deliberately — used precisely and monitored closely, rather than treated as an inexhaustible option, because there is no confirmed backup once resistance catches up to it. That is also part of why treating gonorrhea with leftover antibiotics, or antibiotics prescribed for something else, carries real risk beyond just this one infection: a treatment that doesn't fully clear the bacteria doesn't just fail — it can help the surviving bacteria practice resisting the very drug relied on next.

This progression is part of why the recommended treatment has changed more than once in recent years, and why any single regimen carries something like an expiration date: it remains the right choice only until resistance catches up with it, which is exactly what happened to the antibiotics ceftriaxone replaced.

Why So Many Infections Go Unnoticed at First

Gonorrhea can infect the genitals, rectum, or throat, and a large share of these infections — especially in the throat and rectum — cause no symptoms at all, which is part of why it spreads through networks of partners before anyone realizes anything is wrong 3. Left untreated, gonorrhea can cause pelvic inflammatory disease, ectopic pregnancy, and infertility 3.

More than 600,000 gonorrhea cases were reported in the U.S. in 2023 4, and the true number is almost certainly higher, since throat and rectal infections require site-specific swabs that aren't always part of a routine test. A person can carry and transmit gonorrhea at any of these sites without any of the discomfort that might otherwise prompt testing.

Throat infections are particularly easy to overlook, since they rarely produce a sore throat or any sensation distinct enough to prompt a visit on their own, and they don't always show up on a genital-only test. That gap between where an infection actually lives and where testing looks is one of the more common reasons gonorrhea passes between partners unnoticed.

Who Should Be Screened, and How Often

National screening guidelines call for annual gonorrhea and chlamydia testing in sexually active women under 25, regular screening for men who have sex with men based on individual risk, and testing as part of routine prenatal care 5. Because gonorrhea so often causes no symptoms, screening — not waiting for something to feel wrong — is what catches most infections early enough to prevent complications.

Anyone tested at the genitals alone, without a throat or rectal swab where relevant to their sexual activity, can still be carrying gonorrhea at a site the test never checked. Asking a clinician directly which sites are being tested is a reasonable question, not an unusual one.

Screening intervals are not one-size-fits-all: someone with a single long-term partner and someone with several new partners a year fall under different recommended timelines even within the same guideline, which is why individual risk, not just age or gender alone, shapes how often testing makes sense.

Treating a Partner at the Same Time

Gonorrhea treatment isn't complete until sexual partners are treated too, for the same reason it matters with any curable bacterial STI: an untreated partner can simply pass the infection back. National guidelines call for clinicians to routinely offer expedited partner therapy for gonorrhea, delivering medication or a prescription directly to a partner from the previous 60 days when that partner is unlikely to see a clinician of their own in time 6.

Preventing reinfection depends as much on this step as on the antibiotic itself — a dose of ceftriaxone works exactly as intended, and someone can still test positive again a few weeks later if the person they were exposed to never got treated. That pattern is reinfection, not a sign the original treatment failed.

In practice, this means a diagnosis rarely stays a private matter between one patient and one clinician — notifying recent partners, however that conversation happens, is part of what actually stops the infection from cycling back. Some health departments can help with this notification confidentially when a patient would rather not have the conversation directly.

Gonorrhea vs. Chlamydia, and Getting Retested

Gonorrhea and chlamydia are often tested for together, on the same swab or urine sample, and frequently occur as a coinfection — part of why doxycycline is added to gonorrhea treatment whenever chlamydia hasn't been ruled out. Understanding the difference between gonorrhea and chlamydia matters in practice: how chlamydia is treated involves an oral antibiotic course alone, while gonorrhea now requires an injection specifically because of resistance concerns chlamydia's bacterium doesn't share to the same degree.

Retesting after treatment follows the same logic as with any bacterial STI: a test taken too soon can still pick up genetic material from bacteria that are already dead, so clinicians generally aim a follow-up gonorrhea test window at catching a new infection rather than confirming the last one cleared. Anyone with ongoing exposure risk is a reasonable candidate for periodic rescreening, not just a one-time retest.

Because the two infections are usually tested for on the same sample, there's rarely a reason to test for one without the other — a single visit can answer both questions at once, which is also why treatment plans are built to cover whichever combination the results show.

Common questions

Gonorrhea bacteria have grown resistant to nearly every oral antibiotic that used to work against them, leaving an injectable cephalosporin, ceftriaxone, as the one option guidelines consider reliably effective across the country. Pills alone are no longer considered dependable treatment for gonorrhea on their own.

Not necessarily, but doxycycline is often added to gonorrhea treatment when a chlamydia infection hasn't been specifically tested for or ruled out, because the two infections travel together often enough that covering both is standard practice rather than an assumption either way.

Yes, most often through reinfection from a partner who wasn't treated rather than the original antibiotics failing. That's why partner treatment is considered part of curing gonorrhea, not a separate optional step, and why a positive test weeks later usually points to a new exposure.

Resistant strains exist and are taken seriously enough that public-health agencies monitor them closely, which is part of why ceftriaxone is used carefully and why self-treating with leftover or unrelated antibiotics is discouraged. Most cases still respond fully to current treatment when it's given correctly.

Testing too soon can pick up genetic material from bacteria that are already dead, producing a misleading result, so a follow-up test is generally timed to catch a new infection rather than to double-check the last one cleared. A clinician can advise on timing for a specific situation.

When Gonorrhea Symptoms Need Same-Day Care

  • —Joint pain, swelling, or a skin rash that develops days after infection, together with fever — possible signs of disseminated infection
  • —Severe lower abdominal or pelvic pain, especially with fever, nausea, or vomiting
  • —Pain or swelling in one testicle
  • —Eye pain, redness, or discharge, which needs prompt evaluation separate from genital treatment

Fever with joint pain and a spreading rash, severe pelvic pain, or sudden testicular pain and swelling warrants same-day medical care or an emergency room visit rather than waiting for a routine appointment.

This article is educational and does not replace an in-person evaluation. A clinician can confirm the diagnosis, test for chlamydia and other coinfections, and choose treatment appropriate to a specific situation, including any prior antibiotic allergies.
