Chlamydia treatment and prevention

1-minute read

Chlamydia treatment

Your doctor can usually treat chlamydia, an infection caused by the bacterium Chlamydia trachomatis, with a single course of antibiotics.

You should avoid having sex while taking the antibiotics and for a week after you finish taking them so you don’t pass on the infection to someone else or become re-infected.

It is recommended that you have another test for chlamydia 3 months later to make sure you haven’t been infected again.

If you have chlamydia, anyone you have had sex with in the past 6 months should also be tested and may need treatment at the same time. This is called contact tracing.

As chlamydia is transmitted through unprotected sex, your doctor may suggest you be screened for other sexually transmitted infections and if necessary, you and your partner(s) treated.

Chlamydia prevention

Chlamydia is a sexually transmitted infection (STI), which means you can get it through having unprotected vaginal, anal or oral sex with an infected partner. You can help prevent being infected with chlamydia by practising safe sex. Use a condom when you have vaginal or anal sex, and a condom or dental dam for oral sex.

Remember, many people with chlamydia don’t know they have it.
