Exposed to chlamydia and want the treatment. Which antibiotic, why an exposure is treated before your own result, and how to get it online.

A partner tested positive, or told you they have symptoms, and you want the treatment rather than a reading list. Here is the short version. The first-line treatment in the United States is doxycycline 100 mg by mouth twice a day for seven days [1]. A named exposure is itself a reason to treat. National guidance is to treat the sex partners of someone diagnosed with chlamydia presumptively, without waiting for their own test result [1]. You can get that prescription from a licensed provider by chat, the same day, with no appointment.
Everything below is the reasoning behind those four steps, for the reader who wants to know why the answer is what it is.
There are three regimens in national guidance for uncomplicated infection in non-pregnant adolescents and adults. Doxycycline 100 mg orally twice daily for seven days is first line. Azithromycin 1 g orally as a single dose and levofloxacin 500 mg orally once daily for seven days are the alternatives [1]. A delayed-release doxycycline tablet, 200 mg once daily for seven days, works as well for genital infection and causes fewer stomach upsets, but it costs more [1].
The reason doxycycline leads is worth knowing, because it is not about the genital infection, where both drugs do well. Doxycycline is effective across genital, rectal and throat infection, while azithromycin is weaker against rectal infection. Rectal infection is common alongside genital infection, and it cannot be predicted from what someone reports about their sex life [10] [1]. Treating with the drug that covers every site is how you avoid clearing one infection and leaving another.
The evidence behind the seven-day course is direct. In a randomized trial of 567 people in which every dose was watched being taken, there were no treatment failures at all in the doxycycline group, against five failures, 3.2 percent, with single-dose azithromycin. Azithromycin did not meet the trial's threshold for being considered equivalent [2].
The gap is wider for rectal infection. In a randomized double-blind trial in Seattle and Boston, cure at four weeks was 100 percent with doxycycline against 74 percent with azithromycin among those who completed follow-up, and 91 percent against 71 percent counting everyone who was randomized [3]. The second pair of numbers is the conservative reading and it still favours doxycycline by twenty points.
Two practical points get skipped and then cause a phone call. Take each dose with a full glass of fluid and stay upright afterwards, and do not take it immediately before bed, because the labeling specifically warns about irritation and ulceration of the food pipe when a dose is washed down with too little liquid or taken lying down [4]. It also causes an exaggerated sunburn reaction in some people, so use sunscreen, and stop and tell us if a rash appears [4]. A beach week in the middle of the course is worth planning around.
Azithromycin has not disappeared, and there is one situation where it is the recommended drug rather than the fallback. In pregnancy the recommended regimen is azithromycin 1 g orally as a single dose, with amoxicillin 500 mg three times daily for seven days as the alternative [1] [5]. Doxycycline is contraindicated in the second and third trimesters because tetracyclines cause discolouration of developing teeth [1] [4]. Erythromycin, which older advice still mentions, is no longer recommended [1].
Outside pregnancy, a single dose is a reasonable choice when a seven-day course genuinely is not going to be finished, though guidance notes that testing after treatment may then be worth doing [1]. That is a conversation, not a preference to state up front.
This is the question people find surprising, and the guidance is unambiguous. Sex partners of someone diagnosed with chlamydia should be evaluated, tested and treated presumptively if they had contact in the 60 days before that person's symptoms started or they were diagnosed. If the diagnosed person had no sex in that window, the most recent partner should still be treated [1].
In other words, a named exposure is itself a reason to treat. Waiting for your own test is not the cautious choice here. It leaves an infection running and keeps it moving back and forth between two people. Several online services will only treat you once you hand them a positive result, which is exactly the gap this page exists to close.
Once treated, abstain from sex for seven days after a single-dose regimen, or until a seven-day course is finished and symptoms have settled, and keep abstaining until every partner has been treated as well [1].
The assessment happens in the chat. A provider needs the date and type of the exposure, whether your partner has a confirmed positive result, any symptoms, anything you are already taking, whether you could be pregnant, and any allergy to tetracyclines or macrolides. If treatment is appropriate the prescription is sent electronically to the pharmacy you name, and you collect it there. We confirm we can cover your state before any of that starts, and we will tell you plainly if the right answer is testing first, or an in-person visit.
The recommended test is a nucleic acid amplification test, and it is the test of choice at every exposed site [1]. Which site gets sampled follows the exposure, not convenience. A vaginal swab, collected by you or by a clinician, or a first-catch urine sample covers genital infection in women; first-catch urine is the preferred sample in men; receptive anal sex means a rectal swab and oral sex means a throat swab [1]. A swab you collect yourself is not a compromise: in the evidence reviewed for the US Preventive Services Task Force, self-collected vaginal samples had a sensitivity of 90 to 98 percent against 90 to 100 percent for clinician-collected ones [9]. That is a large part of why this works remotely.
Timing is where people go wrong. No United States guideline sets a validated number of days between exposure and a reliable test [1]. What is known is the incubation period, roughly one to three weeks [8], and a test cannot find an organism that has not yet multiplied enough to be detected. So a test in the first days after an exposure tells you very little, which is the trap, because a negative result feels like an answer. Testing again once the incubation window has passed is what makes a negative result mean something.
There is a matching trap at the other end. A test run sooner than four weeks after treatment can pick up organisms that are already dead and read positive when the infection is gone [1].
There is no comfortable version of this conversation, so the useful thing is to know what you are actually asking. They need treatment, not a debate about who gave what to whom, and chlamydia is frequently silent for months, so the timeline rarely settles anything.
Beyond telling them yourself, there is a formal route called expedited partner therapy, where treatment is provided for a partner who has not been examined, either handed to you to pass on or sent to a pharmacy. Handing over the medication itself is preferred to a prescription [1]. It is not a workaround, it is a studied intervention. In a randomized trial, persistent or recurrent gonorrhoea or chlamydial infection occurred in 10 percent of patients whose partners were offered expedited treatment against 13 percent with standard referral, and those patients were far less likely to report sex with an untreated partner [6].
Its legal status is not the same everywhere. The Centers for Disease Control and Prevention tracks it jurisdiction by jurisdiction, sorting states into permissible, potentially allowable and prohibited, and updates that map over time [7] (confirmed as of 2026-09-09). We will not guess at your state's position. Message us and we will confirm what is available where you are, and what the alternative is if partner therapy is not on the table there.
These two get confused constantly, and treating one as the other either wastes a test or misses a reinfection.
Most chlamydia is straightforward and is handled well remotely. Some of it is not, and the honest list is short. Lower abdominal or pelvic pain, pain with sex, fever, or bleeding between periods can point to infection that has moved upward into the pelvis and needs an examination; pain under the right ribs with nausea belongs on the same list [1]. One-sided testicular pain and swelling needs to be seen [1]. Rectal pain, discharge or bleeding needs assessment in person, because some rectal infections need a longer course than the standard seven days [1]. Pregnancy changes both the regimen and the follow-up [1]. And symptoms that do not settle after a completed course need a second look rather than a second prescription.
If the person who needs care is 18 or under, we treat them only with a parent or guardian's consent.
If contraception is also on your mind after an exposure, the timing rules there are different and stricter, and they are set out in the morning after pill guide.
