    What is chlamydia?

    Chlamydia is a sexually transmitted infection (STI) caused by the bacterium chlamydia trachmatis, and it can pass from one person to another through coming into contact with infected semen or vaginal fluid, usually by having unprotected sex.

    There are a few different ways in which you can contract chlamydia, the most usual being unprotected vaginal, anal or oral sex. But something as simple as contact between your genitals and your partner’s can lead to transmission, even if there’s no ejaculation, orgasm or penetrative sex. 

    You can get it from infected vaginal fluid or from semen getting into your eye too. Chlamydia can also be transmitted through sharing sex toys that haven’t been washed properly, or that are covered by a condom that has already been used by someone who’s infected.

    Who gets chlamydia?

    Anyone who is sexually active can contract chlamydia. But your risk of getting it increases by having unprotected sex with someone who’s already infected. You may have chlamydia without realising as not everyone gets symptoms, so having unprotected sex is always a risk. You can also pass the infection on to your baby if you’re pregnant, so you should be extra careful and use contraception like a condom. 

    Unlike other sexually transmitted diseases, you can’t get chlamydia from toilet seats, sharing baths, swimming pools, sharing cutlery, kissing or hugging.

    How common is chlamydia?

    Chlamydia is one of the most common STIs; around 130 million people have it across the globe.  A study carried out in 2016 estimated that there were 34 cases of chlamydia per 1000 women, and 33 cases per 1000 men. The figures could be even higher since a lot of the time people experience no symptoms and can be unaware of the infection.

    Chlamydia is usually easy to manage and treat if it’s tackled early on, but it can become a serious problem if it’s not addressed. So it’s important to get tested regularly for STIs if you’re sexually active to make sure that you get treatment promptly should a problem arise. If there’s any possibility that you’ve been exposed to chlamydia, you can order a test from us or upload your results for treatment.

    How we source info.

    When we present you with stats, data, opinion or a consensus, we’ll tell you where this came from. And we’ll only present data as clinically reliable if it’s come from a reputable source, such as a state or government-funded health body, a peer-reviewed medical journal, or a recognised analytics or data body. Read more in our editorial policy.

    What causes chlamydia?

    Chlamydia is caused by a bacterium called chlamydia trachomatis. This bacteria transfers from one person to another through unprotected sex or contact with infected vaginal fluids or semen. So you can contract chlamydia even if there’s no penetrative sex. The infection spreads inside the body when the infected cells multiply.

    The infection isn’t limited to the genital area. Women can get chlamydia in the cervix, rectum, or throat, and men can get it in the urethra (inside of the penis), rectum, or throat. And if you’ve had chlamydia in the past and received treatment for it, you can still get re-infected should you have unprotected sex with someone who has it. There’s also the possibility of transmitting the infection to your baby during childbirth.

    What are the symptoms of chlamydia?

    Chlamydia can be a silent condition, meaning that you can be a carrier of the infection without showing or feeling any symptoms. This happens in many cases, so there’s a chance that you may have unprotected sex with someone who carries chlamydia without them being aware of it. So the safest route is to wear a condom and get regularly tested.

    If you do get chlamydia symptoms, they will usually appear anywhere between one and three weeks after having unprotected sex or contact with genital fluids with someone who’s infected. But it may also take months for you to develop any symptoms. 

    Sometimes symptoms may clear up after a couple of days, but that doesn’t mean that the bacteria are gone from your system. You can still have chlamydia and pass it on to sexual partners unless you get treatment.

    At least 70% of women carrying the chlamydia bacteria don’t have any symptoms or they’re so subtle that the carrier doesn’t notice them. If you do get symptoms, they may include:

    • pain when you urinate
    • abdominal pain that could be mistaken for menstrual cramps
    • pain during or after sex
    • unusual vaginal discharge (this can be a strange smell, consistency, or colour)
    • bleeding right after sex, or during
    • bleeding between periods, whether it’s heavy or light spotting

    At least 50% of men with chlamydia have no clear symptoms. But if they do get symptoms, they might include:

    • pain when you urinate
    • white, cloudy, or watery discharge from the tip of your penis
    • testicular pain
    • a burning sensation or itching in the urethra

    If you experience any of these symptoms but haven’t had unprotected sex in a while, it’s better to get tested anyway because you might have been carrying the infection and only just became symptomatic.

    Can chlamydia lead to other problems?

    Yes. Although chlamydia is easy to treat when it’s diagnosed early on, if you don’t get help as soon as possible it can lead to complications.

    For women, untreated chlamydia can spread to the womb and cause pelvic inflammatory disease, a very serious condition that can lead to lifelong infertility or ectopic pregnancies.

    In men, chlamydia can cause serious swelling in the testicles and in the epididymis (the tubes that carry sperm from the testicles) and this can have a long term impact on fertility.

    If you have unprotected anal sex, chlamydia can also infect the rectum and cause general discomfort, itching, a burning sensation, and rectal discharge. It can also affect the throat if you have unprotected oral sex, and the eyes if any infected semen or vaginal fluid comes into contact with them.

    What medications are there for chlamydia?

    Most of the time, antibiotics will treat chlamydia effectively. The success rate is high, with over 95% of chlamydia cases cured with antibiotics, specifically Doxycycline and Azithromycin.

    The ‘go-to’ option when prescribing a treatment for chlamydia is Doxycycline. But if for any reason you can’t take it, Azithromycin will be prescribed as an alternative. If neither of these treatments are suitable because you have an allergy, for example, Amoxicillin and Erythromycin can also be prescribed. These are safe options if you’re pregnant too.

    Antibiotics prescribed to treat chlamydia usually work by giving the immune system time to fight off the infection before the bacteria spread throughout the  body.

    Is there a ‘best’ treatment for chlamydia?

    There isn’t a ‘best’ treatment as such, as each person has specific health needs that will require different medications. But taking into account your health background and your current situation, we can help to find the right medication for you. 

    The first option our clinicians will explore with you is Doxycycline, but it will not be prescribed to you if you have a history of allergy to antibiotics, if you’re pregnant or if you’re prone to any specific side effects like sensitivity to sunlight and stomach upset. If that’s the case, Azithromycin will likely be the best treatment option for you.

    Does chlamydia always need treatment?

    Yes. Even if your chlamydia symptoms end up disappearing, the infection can remain asymptomatic in your body if it’s not treated, and you can still transmit it to a sexual partner or even to your baby during childbirth.

    The treatment for chlamydia is only a short course. It usually lasts for just one week if you’re taking Doxycycline, and two days if you’re taking Azythromycin. And since treatment is so highly effective with the right medication, you are likely to overcome the infection quickly.

    FAQ: Chlamydia

    Have something specific you want to know? Search our info below, or ask our experts a question if you can’t find what you’re looking for.

    How many tablets do I need if I’m taking Doxycycline for malaria?

    The number of tablets you need depends on the number of days you’ll be spending in a risk area. You need to take the tablets 1-2 days before you travel, each day you’re away, and then for 28 days when you get back. So, the number of tablets you need is equal to the number of days you are away, plus 30.

    So, if you’re away for:

    • Up to 10 days, you’ll need 40 tablets,

    • 11 to 18 days, you’ll need 48 tablets,

    • 19 to 26 days, you’ll need 56 tablets,

    • 27 to 34 days, you’ll need 64 tablets,

    • 35 to 42 days, you’ll need 72 tablets,

    • 43 to 50 days, you’ll need 80 tablets.

    For trips of more than 50 days, you may need to make multiple orders.

    How is Doxycycline different to other treatments for chlamydia?

    Doxycycline is the first choice antibiotic used to treat chlamydia. Azithromycin is sometimes prescribed as an alternative if Doxycycline is not suitable for you.

    Doxycycline and Azithromycin are both antibiotics and both work in the same way, but the way you take them is different. Azithromycin is a three day course, and Doxycycline a seven day course.

    Do I need to have a positive test result to order Doxycycline for chlamydia?

    You will need proof of a positive test result to order Doxycycline for chlamydia.

    If you don’t already have proof of a positive test you can order one from us and our pathology lab will process it before your treatment begins.

    If your partner has tested positive for chlamydia, you can begin your treatment before your test result comes back from the lab. But you’ll need to take your test sample before starting the treatment.

    How effective is Doxycycline at treating chlamydia?

    Doxycycline is the most effective treatment for chlamydia. Scientific analysis shows that Doxycycline can have a 100% success rate when a course of treatment is followed correctly.

    Chlamydia is one of the most common STIs in the UK. It is becoming resistant to antibiotics like Doxycycline. This doesn’t mean Doxycycline won’t work, but it can become less effective if you do not follow the treatment exactly as your clinician has told you to.

    Do I need a prescription for Doxycycline?

    If you are ordering Doxycycline for chlamydia you’ll need a prescription for it. You will also need a positive test result. If your partner has tested positive you can get a combined treatment and test kit that allows you to start taking the medication whilst you wait for the result of your test. Prescription and testing are important parts of your treatment as they ensure that you have chlamydia, and not another infection for which a different antibiotic might be more effective.

    You’ll need a prescription if you are ordering Doxycycline as an antimalarial treatment because your clinician will need to check that it’s the best treatment for the area you’re travelling to.

    Doxycycline is generally effective in most risk areas, but some regions have become resistant to certain antibiotics. It’s important to check advice about your particular destination, and our clinicians will discuss this with you during your consultation. You can also get information at the Fit4Travel website where you’ll find information and up to date guidance.

    Why should I buy Doxycycline online with Treated?

    From testing to treatment, our clinicians will be with you every step of the way. Our confidential online consultations means that you will be able to access the treatment that you need without having to visit a clinic in person.

    Not only will our clinicians formulate the best treatment plan for you, they will also check in with you to offer support and guidance after the course of treatment has finished.

    How is Azithromycin different to other treatments for chlamydia?

    Azithromycin is an effective antibiotic used to treat chlamydia, but Doxycycline is the most common treatment because it’s slightly more effective. If you can’t take Doxycycline (for example, if you’re allergic to anything in it) you’ll be prescribed Azithomycin.

    Both tablets are antibiotics that attack and kill chlamydia. Doxycycline is taken over a longer period of time than Azithomycin and comes in a different dosage size.

    Do I need to have a positive test result to order Azithromycin?

    If your sexual partner has tested positive for chlamydia, you don’t need a positive test result for yourself before you can start taking Azithromycin. It’s recommended you collect a sample for testing, but don’t wait for the result to come back before starting the treatment.

    Otherwise, to be prescribed Azithromycin you’ll need a positive chlamydia test result. You can provide this test result before ordering, or you can order a test first and then we’ll advise you on treatment if your test is positive.

    How effective is Azithromycin at treating chlamydia?

    Azithromycin is an effective treatment for chlamydia and has a success rate of over 90%, according to a study published in the New England Journal . However, the more we use antibiotics, the less effective they become at killing infections because the bacteria in them adapt and become resistant to the antibiotic. It’s important to take your course of treatment exactly as your clinician tells you to so that you reduce the risk of antibiotic resistance.

    Do I need a prescription for Azithromycin?

    You’ll need a prescription for Azithromycin because our clinician will need to check that the infection you’ve got is chlamydia. If you’ve got a different type of infection, a different antibiotic might be more effective.

    If your partner hasn’t tested positive, you'll need a positive chlamydia test result to order Azithromycin. You can provide a test result from somewhere else, or you can use our testing service to get your result before starting your course of treatment.

    If your partner has a positive test result, you can order our test + treat kit and start your treatment whilst you wait for your test result.

    Why should I buy Azithhromycin online with Treated?

    Our experts can help you get the diagnosis and treatment you need, without having to visit the clinic in person. Chat to us to get your test online, and if you’re positive, we’ll help you find the treatment you need.

    We’ll check in with you too once you’ve started treatment just to make sure it’s working for you. And if you’re unsure of anything, our experts are here to answer any questions you have.

    How is chlamydia diagnosed?

    Chlamydia is tested and diagnosed using a swab or urine sample. This can be provided by your local sexual health clinic or ordered from us. Men are usually asked to provide a urine sample only, while women will often be asked for either a urine sample or a vaginal swab.

    How long do I need to wait for chlamydia test results?

    It will usually take between seven and ten days for your results to come back. But if you’ve had unprotected sex with someone who has chlamydia, or if they’re already showing chlamydia symptoms, then it’s likely that you’ve contracted the bacteria. In these circumstances, you can start your treatment for the infection even before your results come back.

    If you speak to our clinicians, they will advise you on whether or not you should be waiting for test results, or if you should start your chlamydia treatment as soon as possible

    Can you get side effects from chlamydia treatment?

    Just like any other medication, chlamydia treatment can cause side effects. But not everyone gets them.

    Doxycycline can cause side effects like sensitivity to sunlight, so you need to use high-factor sunscreen if you’re going to be exposed to direct sunlight whilst you’re being treated. It can also cause stomach upset, so you need to remember to eat before you take the tablet.

    Azythromycin can have side effects like sickness, diarrhoea and abdominal pain. If you get more serious side effects like an allergic reaction, characterised by a skin rash, joint pain, swallowing and breathing difficulties, you need to seek emergency medical attention as soon as possible.

    Does chlamydia treatment always work?

    Chlamydia treatment has a 95% effectiveness rate, so it’s extremely likely that it’ll work well for you.

    You might not need to return to a sexual health clinic after your chlamydia treatment is over. But you will need to do another test if you or your partner had sex before you finished the treatment course, if you forgot to take the medication as directed, if you didn’t take it correctly, if you’re pregnant, or if symptoms persist after the treatment course has ended.

    Why should I buy chlamydia treatment online with Treated?

    At Treated, we work hard to make medical treatment and ongoing care easy and convenient. You just need to talk to us about your health and our clinicians will recommend medications that are safe and the right fit for you. From our options, the choice of medication is yours.
