Chlamydia Treatment Guide: Symptoms, Testing and Antibiotics

Top view women reproductive system and pills

What Is Chlamydia?

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.

What Does Chlamydia Look Like?

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:

  • Pain when peeing
  • Unusual discharge from the penis, vagina, or anus
  • Lower tummy pain or pain in the testicles
  • Bleeding between periods or after sex
  • Red, sticky eyes (less common but possible)

Even if your symptoms disappear, the infection can still be there, and you can still pass it on.

Chlamydia Testing: Quick, Free, and Easy

When to Get a Chlamydia Test

You should get a chlamydia test if:

  • You've had unprotected sex
  • A partner has tested positive
  • You have symptoms
  • You're under 25 and sexually active (testing is recommended annually)

At Private Medical Clinic, the sexual health services we offer include discreet and same-day testing with quick results.

What Does a Chlamydia Test Involve?

Testing is straightforward:

  • Urine sample (for those with a penis)
  • Vaginal swab (can often be done yourself)
  • Throat or rectal swabs if needed, based on sexual activity

Results usually come back within 7 working days, but in some cases, treatment for chlamydia may begin immediately if exposure is likely.

Chlamydia Treatment: What You Need to Know

Does Chlamydia Go Away On Its Own?

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.

How Long Can You Have Chlamydia Before It Causes Damage?

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.

Treatment for Chlamydia: Antibiotics That Work

What Chlamydia Treatments Are Available?

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.

48 Hours After Chlamydia Treatment: What to Expect

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:

  • Avoid any sex (oral, vaginal, anal) until 7 full days after treatment ends
  • Make sure your partner(s) are treated too, or you risk getting infected again
  • If symptoms linger after treatment, return to the clinic for a check-up

Telling Your Partners and Staying Protected

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.

Going forward, protect yourself by:

  • Using condoms or dental dams
  • Getting regular STI checks; gonorrhoea is the most commonly co-occurring STI with chlamydia, especially with new partners
  • Washing or covering sex toys before each use

Explore our STI screening packages for ongoing peace of mind.

In Summary: Your Action Plan

  • Get tested regularly
  • Follow your full course of chlamydia antibiotics
  • Avoid sex for at least 7 days after treatment
  • Make sure partners are treated too
  • Speak with your doctor if symptoms persist

Q1: What are the symptoms of chlamydia and how do I know if I have it?


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. The only reliable way to know is through a chlamydia test — testing is fast, simple, and confidential.

Q2: How is chlamydia tested and how long do results take?


Chlamydia is detected via a urine sample or swab (vaginal, urethral, or rectal depending on risk). Private chlamydia testing delivers results within 24–48 hours. No GP referral is needed — book directly, attend the clinic, and receive results quickly with expert advice on next steps.

Q3: What antibiotics treat chlamydia and how effective are they?


Chlamydia is treated with antibiotics — typically azithromycin (single dose) or doxycycline (7-day course). Both are highly effective when completed correctly. A private GP can prescribe the right antibiotic based on your medical history, confirm the infection has cleared, and advise on partner notification.

Q4: What happens if chlamydia is left untreated?


Untreated chlamydia can cause pelvic inflammatory disease (PID), ectopic pregnancy, infertility in both men and women, and increased HIV risk. These complications develop silently over months or years. Early testing and treatment through our sexual health clinic prevents serious long-term damage completely.

Q5: How often should sexually active people get tested for chlamydia?


Anyone sexually active under 25 should test annually or with each new partner. Those with multiple partners should test every 3–6 months. Private sexual health testing is discreet, fast, and doesn't require a GP referral — making regular testing easy, accessible, and completely confidential.
