Chlamydia

What Is Chlamydia?

Chlamydia is a bacterial infection that you get through sexual contact. It's one of the most common STIs in Ireland, which means you're not alone if you get it—loads of people do. The excellent news? It's easily treatable with antibiotics. A simple course of tablets and you're sorted. No lasting damage, no complications if caught early.

How Do You Get It?

Chlamydia spreads through sexual contact—vaginal, anal, or oral sex with someone who has the infection. It can also be passed to a baby during birth, but that's not relevant for most people reading this. You catch it from someone who has chlamydia, usually without knowing they have it (since many people have no symptoms).

Symptoms

• Unusual discharge from the penis, vagina, or rectum—might be clear, white, or yellowish
• Burning or pain when peeing
• Pain during sex (dyspareunia)
• Lower abdominal pain or pelvic pain
• Bleeding between periods or heavier periods (if you menstruate)
• Symptoms can appear 1-3 weeks after infection—but many people have zero symptoms

Just because you feel fine doesn't mean you don't have it. Regular testing is the only way to know for sure.

Testing & Diagnosis

Chlamydia is diagnosed with a simple urine test or swab (from the urethra, cervix, or rectum depending on where you might have been exposed). It's quick, non-invasive, and painless.

Irish clinics offering free tests:

• Your GP (free)
• Sexual Health Clinics (free on the HSE)
• Brook Ireland (sexual health service for young people)
• Pharmacies (some offer free testing)

If you're sexually active, get tested at least once a year—more often if you have multiple partners or new partners.

Treatment

Chlamydia responds brilliantly to antibiotics. Your doctor will prescribe the right course for you.

What to expect:

• A course of antibiotics (usually 1-2 weeks)—commonly azithromycin or doxycycline
• Take all the medication as prescribed, even if symptoms go away
• Avoid sex for at least a week during treatment to avoid reinfection
• Your sexual partner(s) need to be tested and treated too—at the same time
• Follow-up testing after 3-4 weeks confirms it's cleared

That's it. You're done. Back to normal life.

Why It Matters If Left Untreated

If chlamydia hangs around untreated for months, it can lead to pelvic inflammatory disease (PID) in people with a vulva, which can affect fertility. In people with a penis, it can cause epididymitis (inflammation of tubes that store sperm). Again—this is entirely preventable with early treatment. This is why testing matters, especially if you're sexually active.

Prevention

• Condoms—significantly reduce transmission risk (not 100% but very effective)
• Regular testing—at least yearly if you're sexually active, more often with new partners
• Partner notification—tell sexual partners so they can get tested
• Open communication about sexual health status

Support & Resources

Chlamydia is super common—seriously, loads of people get it. There's zero shame in it. Irish sexual health clinics see it constantly and will treat you quickly and discreetly. You can test and get treatment without anyone judging you. If you're worried about telling a partner, most clinics offer partner notification services to make it easier.
