Can I pass on chlamydia after treatment?

Chlamydia is one of the most common sexually transmitted infections (STIs) worldwide. It is caused by the bacterium Chlamydia trachomatis and can affect both men and women. If left untreated, chlamydia can lead to serious health complications, such as infertility and pelvic inflammatory disease. Therefore, it is vital to seek treatment for chlamydia as soon as possible. But what happens after treatment? Can you still pass on chlamydia to others? In this blog post, we will explore the post-treatment considerations for chlamydia and the steps you can take to prevent transmission.

Treatment for Chlamydia

The primary treatment for chlamydia is antibiotics. There are two main options when it comes to antibiotic treatment for chlamydia: single dose antibiotics or a seven-day course of antibiotics.

Single Dose Antibiotics

Single dose antibiotics, such as Azithromycin, are commonly prescribed for treating chlamydia. This means that you take the medication once and it is usually effective in curing the infection. However, it is important to note that even with single dose antibiotics, it is still necessary to abstain from sexual activity for a period of time after treatment to prevent spreading the infection to partners.

Seven-Day Course of Antibiotics

In some cases, a healthcare provider may prescribe a seven-day course of antibiotics, such as Doxycycline, to treat chlamydia. This means taking the medication for a full week to ensure that the infection is completely eradicated. Again, it is crucial to refrain from sexual activity while undergoing this treatment.

Completing the Full Course of Antibiotics

Regardless of whether you are on a single dose or a seven-day course of antibiotics, it is essential to complete the full course as prescribed. Even if you start feeling better, stopping the medication prematurely can lead to treatment failure and the persistence of the infection.

Abstinence from Sexual Activity During Treatment

During your course of antibiotic treatment, it is recommended to abstain from any sexual activity. This includes vaginal, anal, and oral sex. This precaution is crucial because even though you may be actively treating the infection, there is still a possibility of passing it on to your sexual partner.

Post-Treatment Considerations

Once you have completed your treatment for chlamydia, you may wonder about the duration of the post-treatment period and the risk of passing on the infection to others.

Duration of Post-Treatment Period

The typical recommendation is to abstain from sexual activity for 7 days after a single dose of antibiotics or until the completion of a 7-day course of antibiotics. This period allows sufficient time for the antibiotics to work and for the infection to be cleared from your body.

Risk of Passing on Chlamydia After Treatment

After completing your treatment, the risk of passing on chlamydia decreases significantly. The antibiotics are effective in killing the bacteria and curing the infection, but it is essential to remember that there is still a small chance of reinfection if you are exposed to the infection again. Moreover, if you have had sexual contact with an infected partner before diagnosis and treatment, there is a chance that you may have unknowingly transmitted the infection to others during that time.

Abstinence to Prevent Spreading the Infection

To prevent spreading chlamydia to your sexual partners, it is essential to practice abstinence from sexual activity until you have completed your treatment and the recommended post-treatment period. This responsibility to abstain applies to both individuals who have chlamydia and those who have been treated as a precautionary measure if they were exposed to the infection.

Importance of Informing Sexual Partners

It is crucial to inform your sexual partners if you have been diagnosed with chlamydia and have undergone treatment. This allows them to seek testing and treatment to prevent further transmission of the infection. It can be an uncomfortable conversation to have, but it is crucial for the health and well-being of both you and your partners.

Preventive Measures

To reduce the risk of getting chlamydia or transmitting it to others, there are several preventive measures you can take.

Regular Testing for Chlamydia

Regular testing for chlamydia is crucial, especially if you engage in sexual activity with multiple partners or if you have had unprotected sex. Getting tested allows for early detection and treatment if necessary, which can help prevent the spread of the infection.

Safe Sexual Practices

Practicing safe sex is essential in preventing the transmission of chlamydia and other STIs.

Using Condoms

Using condoms consistently and correctly during every sexual encounter can significantly reduce the risk of contracting and spreading chlamydia. Condoms act as a barrier, preventing direct contact with infected bodily fluids.

Limiting Sexual Partners

Limiting the number of sexual partners reduces the risk of exposure to chlamydia. Engaging in a monogamous relationship with a partner who has been tested and is free of STIs can significantly decrease the risk.

Partner Treatment and Testing

If you have been diagnosed with chlamydia, it is essential that your sexual partners also get tested and treated, if necessary. Treating all partners simultaneously helps prevent reinfection and further transmission of the infection.


Treating chlamydia with antibiotics is crucial for your health and the prevention of complications. It is important to understand the post-treatment considerations, such as abstaining from sexual activity for a specific period, to prevent passing on the infection to others. By taking the necessary precautions and practicing safe sex, you can reduce the risk of chlamydia transmission and protect both yourself and your sexual partners. Regular testing and open communication with your partners are essential for maintaining sexual health and preventing the spread of chlamydia and other STIs.
