Chlamydia is one of the most common sexually transmitted infections (STIs) in the UK. A type of bacteria causes it and often spreads through unprotected vaginal, anal, or oral sex. The tricky part? Most people don't get symptoms, meaning it can go unnoticed for weeks or months.
Left untreated, chlamydia can cause serious complications like infertility. That's why regular chlamydia tests and early treatment are so important.
If you've been diagnosed with chlamydia, prompt treatment with antibiotics is highly effective and helps prevent long-term complications. Most people make a full recovery when they complete their prescribed treatment and avoid sexual contact until it is safe to resume. Our sexual health clinics offer discreet testing and treatment across our UK locations if you need support at any stage.
If you're wondering what chlamydia looks like, the answer can be a bit misleading, because in most cases, it doesn't look like anything at all. Around 70% of women and 50% of men won't notice any symptoms.
When symptoms do show up, they might include:
Even if your symptoms disappear, the infection can still be there, and you can still pass it on.
You should get a chlamydia test if:
At Private Medical Clinic, the sexual health services we offer include discreet and same-day testing with quick results.
Testing is straightforward:
Results usually come back within 7 working days, but in some cases, treatment for chlamydia may begin immediately if exposure is likely.
No,it won't go away without proper chlamydia treatment. Ignoring it can cause long-term damage, even if you're not noticing any symptoms.
Chlamydia can be silently active in your system for months, sometimes even years. But damage can begin in just a few weeks, especially for women, where it can lead to pelvic inflammatory disease (PID), infertility, or ectopic pregnancy. Men may experience testicular pain and reduced fertility.
Chlamydia is treated using antibiotics prescribed by a healthcare professional. The exact antibiotic depends on your symptoms, medical history, pregnancy status and current clinical guidance.
Most uncomplicated infections are treated successfully with:
It's important to complete the full course of antibiotics exactly as prescribed, even if your symptoms improve before treatment is finished.
When taken correctly, antibiotic treatment is highly effective at clearing the infection.
Chlamydia is treated with antibiotics, and the good news is, treatment has a 95% plus success rate.
The two main types of chlamydia antibiotics prescribed are:
Our team at Private Medical Clinic will advise you on the right chlamydia medication based on your situation.
Several antibiotics can effectively treat chlamydia. Your clinician will prescribe the most appropriate option based on current treatment guidelines and your individual circumstances.
Never use leftover antibiotics or medication prescribed for someone else. Taking the correct antibiotic at the correct dose is essential for successfully treating the infection.
You may start feeling better within a few days. Most symptoms will clear up within 2-4 weeks. But just because you're feeling okay doesn't mean you're no longer contagious.
Here's what to remember:
Although antibiotics begin working soon after treatment starts, the infection may take a little longer to clear completely.
Many people notice their symptoms begin to improve within a few days, but this varies between individuals.
As a general guide:
Even if you feel better quickly, continue taking all prescribed medication and avoid sexual activity until your healthcare professional advises it is safe to resume.
Like all medicines, antibiotics used to treat chlamydia can occasionally cause side effects.
Common side effects include:
Most side effects are mild and improve after treatment finishes.
If you develop severe diarrhoea, difficulty breathing, swelling or signs of an allergic reaction, seek urgent medical attention immediately.
Most people do not need an immediate test to confirm that treatment has worked if they have completed their antibiotics and their symptoms have resolved.
However, repeat testing may be recommended if:
People under 25 and those at higher risk of sexually transmitted infections are often advised to have another chlamydia test around three months after treatment to check for reinfection. If you're at ongoing risk, it's also worth considering screening for genital warts or HPV alongside your chlamydia retest. For further advice on retesting and reducing your risk of reinfection, patient charities such as Terrence Higgins Trust offer confidential guidance and support.
In some situations, treatment may be offered before test results are available. For example, if a recent sexual partner has tested positive for chlamydia or your clinician believes there is a high likelihood of infection, starting treatment immediately may help prevent complications and reduce transmission.
Whenever possible, testing is still recommended to confirm the diagnosis and identify any additional sexually transmitted infections that may require treatment, such as genital warts, herpes or HIV.
If you test positive, it's important to let your sexual partners from the past 6 months know. If that feels uncomfortable, one of our health advisers can notify them anonymously on your behalf.

Chlamydia is often called "the silent infection" , most people have no symptoms at all. When present, signs include unusual discharge, burning urination, pelvic pain, testicular pain, or pain during sex.

You should avoid vaginal, anal and oral sex until you and your partner(s) have completed treatment and at least seven days have passed after finishing antibiotics. This helps prevent reinfection and transmission.
Doxycycline begins working soon after you start taking it, but symptoms may take several days to improve. Always complete the full seven-day course, even if you feel better.
Many people have no noticeable symptoms after 48 hours, while others may begin to feel an improvement. However, the infection may not yet be fully cleared, so you should continue taking your medication and avoid sexual activity until advised.
