Gonorrhea treatment is now a single injection of the antibiotic ceftriaxone, replacing the oral pills and drug combinations once used. The bacterium has grown resistant to nearly every older option, so current CDC guidance recommends ceftriaxone alone as the reliable cure. It works fast, but you still need to avoid sex and treat partners to keep it from coming back.

The bottom-line difference
If you're comparing "the shot" with the antibiotics gonorrhea used to be treated with, the comparison is short: the old drugs no longer work dependably, and ceftriaxone does. The single ceftriaxone injection is the one recommended regimen for uncomplicated gonorrhea CDC, 2021. Older oral antibiotics — the fluoroquinolones, earlier cephalosporin pills, and others — have been dropped because the bacteria outran them. These aren't equal choices on a menu. It's the current standard against options that resistance retired.
What each one is
Ceftriaxone (the injection used today)
Ceftriaxone is a cephalosporin antibiotic given as a single intramuscular shot, usually in the muscle of the buttock or thigh. It kills the bacterium that causes gonorrhea, Neisseria gonorrhoeae, by attacking the cell wall it needs to survive. Because it's an injection, the full dose lands in your bloodstream at once, with no relying on you to finish a bottle of pills. That's part of why it's so effective. The main side effect is soreness at the injection site for a day or two.
The old oral antibiotics
For decades, gonorrhea was treated with pills — penicillins, then tetracyclines, then fluoroquinolones (drugs like ciprofloxacin), and at times oral cephalosporins. Each was convenient and cheap. But gonorrhea has progressively developed resistance to nearly every antibiotic ever used against it CDC, drug-resistant gonorrhea. When a drug stops killing enough of the bacteria, an apparently "treated" infection quietly survives and spreads, and those oral regimens were pulled from guidelines for that reason.
The key differences
Reliability against resistance
Ceftriaxone still clears the infection at the dose it's given. The retired orals increasingly don't. Taking the wrong drug, or a dose too low to finish the job, lets resistant strains persist and pass on, and that's part of why gonorrhea became one of the hardest STIs to keep treatable. Using the right drug at the right dose protects your cure and protects the drug for everyone.
How it's taken
A shot is one-and-done, given in front of a clinician, so there's no half-finished course. Pills depend on you taking every dose on schedule, and the most common treatment mistake is stopping once you feel better, which leaves a partly-treated infection behind.
Side effects and interactions
Ceftriaxone's main downside is a sore injection site. The older oral antibiotics carried their own baggage depending on the drug. Doxycycline, for example — still used for chlamydia and some other infections — can cause stomach upset and sun sensitivity, so it's taken with food while you stay out of strong sun. None of that applies to a single ceftriaxone shot.
Side-by-side comparison
| Feature | Ceftriaxone (current) | Older oral antibiotics |
|---|---|---|
| Form | Single intramuscular injection | Pills, often multi-dose |
| Still recommended? | Yes — the one recommended regimen | No — retired due to resistance |
| Works against today's strains | Yes | Increasingly fails |
| Depends on you finishing a course | No — given on the spot | Yes |
| Main drawback | Soreness at injection site | Resistance; drug-specific side effects |
Which one applies to you
For uncomplicated gonorrhea, it's the ceftriaxone injection, and there isn't a current oral alternative your clinician would reach for first. If you've read about pill regimens online or remember being treated with antibiotics years ago, that information is out of date. A few situations change the picture: a documented severe allergy to cephalosporins, an infection in the throat (which is harder to clear), or a case that isn't responding. Those are decisions a clinician makes individually, and they don't put the old orals back on the table for most people.
Gonorrhea and chlamydia often travel together, so you may be treated for both. And if your symptoms turn out to be something else entirely, like trichomoniasis, the medicine is different — see trichomoniasis treatment for how that parasite is handled. A real diagnosis matters because there's no over-the-counter product, yogurt, garlic, or detox that cures a bacterial STI. You need the specific prescription drug matched to the specific infection.
The practical next step
Treatment for gonorrhea usually looks like a single shot at a clinic, and it's often free or low-cost at a health department or Planned Parenthood. Many of these places can treat your partners too without a separate visit, through expedited partner therapy, where your clinician sends them the medicine or a prescription. Skipping partner treatment is one of the two main ways an infection bounces straight back.
- Confirm the diagnosis with a test rather than guessing — get tested if you haven't already, since symptoms overlap heavily across STIs.
- Get the ceftriaxone injection from a clinician; don't try to source antibiotics on your own.
- Avoid sex until you and your partners have finished treatment and any wait period your clinician gives — often about a week after a single-dose treatment — so you don't pass it back and forth.
- Make sure partners are treated, in the same window, even if they feel fine.
- Ask whether you need a follow-up test. Feeling better in a few days is not proof of cure, and some cases call for a retest weeks to months later.
When to talk to a clinician
See a clinician promptly if you have symptoms like discharge, burning with urination, or pelvic pain, or if a partner tells you they tested positive. Go back if symptoms don't improve within a few days of the shot, or if they clear and then return, which can signal a re-exposure or, less commonly, a strain that needs a different approach. Untreated gonorrhea causes real harm. In women it can ascend to cause pelvic inflammatory disease (infection of the reproductive organs that can damage the fallopian tubes and threaten fertility), and in men it can cause epididymitis (painful inflammation of the tube behind the testicle). If you're not sure how soon after a possible exposure a test will be accurate, check when to test after exposure before you book.
