Most STDs are curable with a short course of antibiotics, and the ones that aren’t curable can be managed well enough that symptoms stay minimal or disappear entirely. The key factor is which type of infection you have: bacterial, viral, or parasitic. Each category has a different treatment path, different timelines, and different expectations for what “getting rid of it” actually looks like.
Bacterial STDs Are Fully Curable
Chlamydia, gonorrhea, and syphilis are all caused by bacteria, which means antibiotics can eliminate them completely. These are the most straightforward STDs to treat, and in many cases, a single dose or a short course of medication is all it takes.
Chlamydia is treated with a seven-day course of oral antibiotics taken twice daily. It’s one of the most common STDs and also one of the easiest to clear. Gonorrhea requires a single antibiotic injection. Because gonorrhea has developed resistance to many older antibiotics, the injectable form is now the standard recommendation. If your doctor hasn’t ruled out chlamydia at the same time, you’ll typically be treated for both simultaneously, since the two infections frequently occur together.
Syphilis is treated with a penicillin injection. If it’s caught in the early stages (primary, secondary, or early latent), a single injection clears it. Late-stage syphilis requires three injections given one week apart. The earlier syphilis is caught, the simpler treatment is, which is one reason routine screening matters.
For all three of these infections, you should get retested three months after treatment. This isn’t because the antibiotics failed. It’s to check whether you’ve been reinfected, which is common if a sexual partner wasn’t treated at the same time.
Viral STDs Can Be Managed but Not Cured
Herpes, HIV, hepatitis B, and HPV are caused by viruses. Antibiotics don’t work on viruses, so these infections can’t be eliminated from your body the way bacterial STDs can. That said, “not curable” doesn’t mean “not treatable,” and the outlook for each of these varies significantly.
Herpes
Genital herpes is a chronic, lifelong infection, but antiviral medications reduce the frequency and severity of outbreaks and lower the risk of passing the virus to partners. Three antiviral options are available, and all appear equally effective. For a recurrent outbreak, treatment courses range from one to five days depending on the specific medication and dosing schedule your doctor chooses. Some people take antiviral medication daily as suppressive therapy, which keeps the virus inactive for long stretches and significantly reduces transmission risk. Many people with herpes go months or years between outbreaks, especially with suppressive treatment.
HPV
HPV is the most common sexually transmitted infection, and for most people with a healthy immune system, the virus clears on its own within one to two years. There’s no antiviral medication that targets HPV directly. If the infection causes genital warts, those can be removed by cutting or burning them off, but the underlying virus resolves on its own in the majority of cases. Certain high-risk HPV strains can lead to cervical or other cancers over time, which is why routine Pap smears and HPV screening matter for early detection.
HIV
HIV requires lifelong treatment with antiretroviral therapy, but modern medications can reduce the virus to undetectable levels in the blood. At undetectable levels, HIV cannot be transmitted sexually. If you think you’ve been exposed to HIV very recently, post-exposure prophylaxis (PEP) may prevent infection if started within 72 hours. For ongoing prevention, pre-exposure prophylaxis (PrEP) taken daily reaches maximum protection for receptive anal sex after about seven days and for receptive vaginal sex after about 21 days.
Parasitic STDs Are Curable With Simple Treatments
Trichomoniasis is caused by a parasite and is cured with a single oral dose of antiparasitic medication. It’s extremely common, especially in women, and often causes no symptoms at all. Women who test positive should be retested three months after treatment.
Pubic lice are treated with an over-the-counter lotion containing 1% permethrin or a mousse containing pyrethrins. You apply it to the infested area, leave it on for the recommended time, then wash it off. After treatment, remove remaining nits (eggs) with your fingernails or a fine-toothed comb. Repeat treatment in 9 to 10 days if you still find live lice. Machine-wash all clothing, towels, and bedding used in the 2 to 3 days before treatment in hot water (at least 130°F) and dry on the hot cycle. Anything that can’t be washed should be dry-cleaned or sealed in a plastic bag for two weeks.
Getting Tested at the Right Time
Treatment starts with an accurate diagnosis, and testing too soon after exposure can produce a false negative. Each STD has a different window period before it shows up reliably on a test:
- Chlamydia and gonorrhea: One week catches most infections; two weeks catches nearly all.
- Syphilis: One month catches most; three months catches nearly all.
- HIV (blood test): Two weeks catches most; six weeks catches nearly all.
- Herpes (blood test): One month catches most; four months catches nearly all.
- Trichomoniasis: One week catches most; one month catches nearly all.
- Hepatitis B: Three to six weeks.
- Hepatitis C: Two months catches most; six months catches nearly all.
If you test negative but were tested early in the window, consider retesting at the longer interval to be sure.
Why Your Partner Needs Treatment Too
Treating yourself without addressing your sexual partners is one of the most common reasons people end up reinfected. For bacterial STDs like chlamydia and gonorrhea, a practice called expedited partner therapy allows your doctor to write a prescription for your partner without examining them directly. You pick up the medication and deliver it to your partner yourself. This option is legally available in most states, though the specifics vary by location.
For pubic lice, all sexual partners from the past month should be informed and treated. Avoid sexual contact until both you and your partners have completed treatment and confirmed the infestation is gone.
What to Expect After Treatment
For bacterial STDs, symptoms typically start improving within a few days of starting antibiotics, though you should finish the full course if one was prescribed. Avoid sexual contact for seven days after completing treatment (or seven days after a single-dose treatment) to prevent spreading the infection before it’s fully cleared.
For viral STDs like herpes, antiviral medication controls outbreaks but doesn’t eliminate the virus. You may notice outbreaks become less frequent and less severe over time even without medication, as your immune system builds a stronger response. HPV often resolves without any intervention at all.
The three-month retest is one of the most important and most skipped steps in STD treatment. Reinfection rates for chlamydia and gonorrhea are high, particularly when partners go untreated. A quick follow-up test at the three-month mark catches repeat infections early, before they cause complications or spread further.
