What Happens If You Have Sex While Being Treated for Chlamydia?

Chlamydia is a common sexually transmitted infection (STI) caused by the bacterium Chlamydia trachomatis. It often presents without noticeable symptoms, leading many individuals to be unaware they are infected. Despite its often silent nature, chlamydia can lead to serious health complications if left untreated, making timely and complete antibiotic treatment important. Treatment aims to eliminate the bacteria and prevent potential long-term issues such as pelvic inflammatory disease in women.

Sexual Activity During Chlamydia Treatment

Engaging in sexual activity while undergoing treatment for chlamydia carries significant risks, even when using condoms. Antibiotics typically require seven days to effectively clear the bacterial infection. During this period, the Chlamydia trachomatis bacteria may still be present and transmissible.

While condoms offer a barrier, they do not provide absolute protection against STIs like chlamydia. Transmission can occur through contact with infected areas not covered by a condom, such as through genital-to-genital rubbing or oral sex. The risk of passing the infection to a partner remains elevated throughout the treatment period.

Reasons for Abstinence During Treatment

Healthcare providers strongly advise abstaining from all forms of sexual activity during the entire course of chlamydia treatment. This prevents transmission of the infection to sexual partners.

Abstinence also ensures the full eradication of the bacteria from the infected individual’s system without interruption. Re-infection from an untreated partner is a common reason for treatment failure and can perpetuate the cycle of transmission. Avoiding sexual contact until treatment is complete and partners are also treated reduces the risk of re-acquiring the infection and developing complications.

Confirming Cure and Preventing Future Infections

After completing the prescribed antibiotic course, follow-up steps are important to confirm the infection is gone and to prevent future occurrences. The Centers for Disease Control and Prevention (CDC) recommends retesting approximately three months after treatment for chlamydia. This retest primarily aims to detect potential re-infections, which are common and can lead to complications such as pelvic inflammatory disease.

Crucially, all sexual partners from the recent past, typically those within the last 60 days, should be notified, tested, and treated. This step is vital to prevent re-infection of the treated individual and to stop further community spread. Engaging in broader safe sex practices, including consistent and correct condom use, regular STI screening, and open communication with partners, also helps reduce the risk of future infections.
