The first-line cure for gonorrhea is a single intramuscular injection of ceftriaxone 500 mg, given in the clinic — this is the treatment recommended by the CDC 2021 STI guidelines and the WHO. If a chlamydia co-infection has not been ruled out, a 7-day course of doxycycline is added. Gonorrhea is completely curable when treated correctly and early.
As a practising andrologist, I see gonorrhea most weeks. Unlike its quieter cousin chlamydia, gonorrhea usually announces itself — the thick discharge and the burning send men in fast, often within days. The mistake I see again and again is a man taking a random antibiotic from a pharmacy, half-treating the infection, and breeding resistance. Gonorrhea today is genuinely harder to kill than it was a decade ago, so the right injection, the partner treated, and a retest is the only protocol I trust. Let me walk you through the treatment, the testing, and the symptoms.
Gonorrhea treatment is a single ceftriaxone 500 mg intramuscular injection (1 g if you weigh 150 kg or more), per the CDC 2021 STI Treatment Guidelines and the WHO. If chlamydia has not been excluded, doxycycline 100 mg twice daily for 7 days is added. The infection is confirmed with a painless first-void urine test, the partner must be treated at the same time, and — because reinfection and antibiotic resistance are real — I retest at three months.
Quick Facts
- Gonorrhea is a bacterial STI caused by Neisseria gonorrhoeae, spread through vaginal, anal and oral sex.
- In men it is usually symptomatic — a thick, yellow-green penile discharge and burning urine, appearing fast (2–5 days after exposure).
- It is diagnosed by a painless first-void urine NAAT (PCR); a urethral swab with Gram stain and culture is added when resistance testing is needed.
- The cure is a single ceftriaxone 500 mg injection (CDC 2021); the partner must be treated and you should retest at three months.
- Left untreated it can cause epididymitis and threaten fertility; in women it can climb to cause pelvic inflammatory disease and infertility.
- Gonorrhea is becoming resistant to antibiotics worldwide — the reason self-medication is dangerous (WHO).
Everything that matters, in 60 seconds
The essentials an andrologist wants every man to know — how it is treated, what it does, and why the right cure matters more than ever.
The cure
A single ceftriaxone 500 mg injection into the muscle (CDC 2021). Doxycycline is added if chlamydia is not excluded. Simple, fast and highly effective when done properly.
The first sign
Usually a thick, pus-like yellow-green discharge from the penis and burning when you urinate — appearing quickly, about 2–5 days after exposure.
How it is diagnosed
A painless first-void urine NAAT (PCR) — no blood, no penile swab needed for the diagnosis. A swab and culture are added when resistance needs checking.
Why resistance matters
N. gonorrhoeae has grown resistant to nearly every antibiotic thrown at it. Half-treating with a random pill breeds resistant strains — the reason a proper injection beats self-medication.
If left untreated
Can cause epididymitis and threaten fertility in men, and pelvic inflammatory disease and infertility in women. Rarely it spreads to the blood and joints (disseminated infection).
Partner & retest
Every partner must be treated — even without symptoms — or you simply re-catch it. Because reinfection is common, I retest at around three months.
Gonorrhea treatment: the injection that cures it
This is the part that matters most, so let me be exact and current. For years the advice was “dual therapy” — ceftriaxone plus azithromycin. That has largely been retired. The CDC 2021 STI Treatment Guidelines now recommend a single antibiotic for uncomplicated gonorrhea of the urethra, rectum or throat:
- Recommended (first-line): Ceftriaxone 500 mg as a single intramuscular (IM) injection — a dose of 1 g is used if you weigh 150 kg (about 300 lb) or more.
- If chlamydia has not been ruled out: add doxycycline 100 mg orally twice daily for 7 days (chlamydia rides along with gonorrhea very often).
- If ceftriaxone is unavailable: gentamicin 240 mg IM plus azithromycin 2 g orally as a single dose is the recognised alternative.
- Pharyngeal (throat) gonorrhea is harder to clear, so a test-of-cure is advised 7–14 days after treatment.
A few rules I give every patient: abstain from sex for 7 days after the injection so you neither pass it on nor get reinfected; every partner from the last 60 days must be treated, even with no symptoms; and because reinfection rates are high, come back for a retest at around three months. Done this way, gonorrhea is cured — the discharge and burning typically settle within a few days.
What is gonorrhea?
Gonorrhea is an infection caused by the bacterium Neisseria gonorrhoeae, a gram-negative diplococcus. It is one of the most common bacterial STIs in the world and, in men, one of the leading causes of urethritis — inflammation of the urine pipe. It can infect the urethra, the rectum, the throat and the eyes, and in women the cervix — anywhere infected sexual fluid makes contact.
What sets it apart from chlamydia is speed and volume: gonorrhea tends to produce a heavier, more obvious discharge and to do so faster. That is a mixed blessing. It means men usually notice and seek help early — but it also means the temptation to grab a pharmacy antibiotic and “sort it out quietly” is strong, and that is exactly how resistant infections are created.
Gonorrhea symptoms in men
In men, gonorrhea is usually symptomatic, and the symptoms come on quickly — typically 2–5 days after exposure. The classic picture is:
- Thick, pus-like penile discharge — often yellow, green or white, and more profuse than the scant discharge of chlamydia.
- Burning or pain on passing urine (dysuria).
- Testicular pain or swelling — a warning that the infection has reached the epididymis.
- Rectal pain, discharge or bleeding after receptive anal sex (often silent).
- Throat infection after oral sex — almost always symptom-free.
- Red, discharging eye (conjunctivitis) if infected fluid reaches the eye by hand.
In women gonorrhea is far quieter — many have no symptoms until it has climbed to cause pelvic inflammatory disease, which is why treating the partner is non-negotiable. And a crucial clinical point: gonorrhea and chlamydia travel together so often that we treat for both unless chlamydia has been specifically excluded.
How is gonorrhea diagnosed?
The test is simpler than most men fear — no blood, and no penile swab needed just to make the diagnosis. The gold standard is a NAAT (nucleic acid amplification test), a gonorrhea PCR, done in men on a first-void urine sample — the first part of your stream in a cup. It is highly accurate and completely painless, and the same sample is routinely tested for chlamydia at once.
Where the history calls for it — after receptive anal or oral sex — a rectal or throat swab is added, because those infections are almost always silent. And when the discharge is being sampled, a urethral swab with a Gram stain (which shows the gram-negative intracellular diplococci) and a culture can be taken: culture matters because it lets the lab test which antibiotics still work — increasingly important in the age of drug-resistant gonorrhea. I also co-test for the infections that keep gonorrhea company — our pages on chlamydia, syphilis and HIV explain what each one looks for.
Antibiotic-resistant gonorrhea — why self-medication is dangerous
Here is the single most important reason to be treated properly rather than guessing at a pharmacy. Neisseria gonorrhoeae has, one by one, defeated nearly every antibiotic we have used against it — penicillins, tetracyclines, fluoroquinolones and now, in places, the cephalosporins themselves. The WHO tracks multidrug- and extensively drug-resistant gonorrhea as a global priority threat. Every half-finished, sub-standard course of antibiotics selects for the toughest bacteria and pushes us closer to strains nothing can touch. That is why the correct injectable dose, given once and completely, protects not only you but everyone you might pass the infection to.
Complications if gonorrhea is left untreated
Treated early, gonorrhea is a footnote. Left to simmer, it climbs — and as an andrologist, the fertility consequences are my particular concern.
Epididymitis and male fertility
When gonorrhea ascends the tract it inflames the epididymis — the coiled tube above the testicle where sperm mature — causing a tender, swollen testicle. Repeated or untreated epididymo-orchitis can scar the ducts that carry sperm and impair semen quality, which is why I treat genital infections early and aggressively.
Pelvic inflammatory disease in women
In a female partner, untreated gonorrhea can climb into the upper genital tract and cause pelvic inflammatory disease, raising the long-term risk of ectopic pregnancy, chronic pelvic pain and infertility.
Disseminated gonococcal infection
Rarely, the bacterium spills into the bloodstream and causes disseminated gonococcal infection — fever, a skin rash, and painful, swollen joints (a form of septic arthritis). It is uncommon, but it is a reminder that an “ignored” genital infection can surface far from where it began.
Gonorrhea vs chlamydia: how to tell
Men constantly confuse these two, and because we test for and often treat them together, here is a clean comparison. Both are bacterial, both can damage fertility through epididymitis — but the treatment is different, which is exactly why a proper test matters.
| Gonorrhea | Chlamydia | |
|---|---|---|
| Organism | Neisseria gonorrhoeae | Chlamydia trachomatis |
| Discharge | Thick, pus-like, yellow-green, profuse | Watery or cloudy, scant |
| Symptom onset | 2–5 days (fast) | 1–3 weeks |
| Symptomatic in men? | Usually yes | About half have none |
| First-line treatment | Ceftriaxone 500 mg IM ×1 (CDC 2021) | Doxycycline 100 mg twice daily × 7 days |
| Co-infection | Often with chlamydia | Often with gonorrhea |

How to prevent gonorrhea
Prevention is genuinely simple, and none of it is exotic:
- Use condoms correctly and consistently with new or non-monogamous partners.
- Fewer partners, and mutual testing before you stop using condoms in a relationship.
- Get tested after any new partner or condomless sex — you cannot rely on a partner having symptoms.
- Always treat partners, and retest at around three months, because reinfection from an untreated partner is the commonest reason gonorrhea “comes back.”
In my STD practice, gonorrhea is the infection men actually feel — that thick discharge and the burning bring them in within days, which is a gift, because it means we can treat it before it damages anything. The trap I watch men fall into is the pharmacy shortcut: a friend’s leftover antibiotic, or a single tablet bought over the counter. It half-works, the discharge eases, and they assume it is gone — while a partly treated, now more resistant infection quietly persists. Please do not do this. One correct injection, the partner treated in the same window, and a retest at three months — that is the whole cure, and it costs less than the fertility work-up a neglected infection can lead to.
When to see a doctor
See a doctor — or simply get tested — if you have a penile discharge, burning when you urinate, testicular pain or swelling, a partner who tested positive, or condomless sex with a new partner. With gonorrhea, do not wait it out and do not self-medicate: the discharge may settle on a random pill while the infection persists and resistance builds. A first-void urine test is painless, confidential and fast, and the treatment is a single visit.

Frequently asked questions
How is gonorrhea treated?
With a single intramuscular injection of ceftriaxone 500 mg (1 g if you weigh 150 kg or more), per the CDC 2021 guidelines. If chlamydia has not been excluded, doxycycline 100 mg twice daily for 7 days is added. The partner must be treated too, and a retest at three months is advised.
Can gonorrhea be cured permanently?
Yes — gonorrhea is completely curable with the correct antibiotic injection. But treatment gives you no lasting immunity, so you can catch it again. That is why every partner must be treated and why reinfection is common if a partner is missed.
What are the symptoms of gonorrhea in men?
Typically a thick, yellow-green, pus-like discharge from the penis and burning on urination, appearing quickly — usually 2–5 days after exposure. Testicular pain, or silent rectal and throat infections, can also occur.
How soon do gonorrhea symptoms show?
Usually within 2–5 days of exposure — faster than chlamydia, which takes 1–3 weeks. In women, and in throat or rectal infections, gonorrhea is often silent.
Is a single injection enough to cure gonorrhea?
For uncomplicated urethral, rectal or throat gonorrhea, yes — a single ceftriaxone 500 mg injection is the recommended cure (CDC 2021). Doxycycline is added only if chlamydia has not been ruled out, and throat infections need a test-of-cure after 1–2 weeks.
Can I treat gonorrhea with tablets from a pharmacy?
Please do not. Gonorrhea has become resistant to many oral antibiotics, and a half-dose from a pharmacy often eases the discharge without curing the infection — while breeding resistant bacteria. The reliable cure is the correct injectable dose, given once and completely, after a proper test.
What is the difference between gonorrhea and chlamydia?
Gonorrhea usually causes a thick, profuse, yellow-green discharge within 2–5 days and is treated with a ceftriaxone injection; chlamydia causes a scant, watery discharge (or none) after 1–3 weeks and is treated with doxycycline tablets. They frequently occur together, so we often test for and treat both.
Does my partner need treatment too?
Yes — absolutely, and even if they have no symptoms. If your partner is not treated you will simply be reinfected. Both of you should complete treatment and avoid sex for 7 days afterwards.
Can gonorrhea cause infertility in men?
It can, if left untreated. Gonorrhea can inflame and scar the epididymis and seminal ducts, impairing sperm transport and quality. In women it can cause pelvic inflammatory disease and infertility. Early treatment is the way to prevent this.
