Antibiotics for chlamydia are highly effective, and most of the time, chlamydia goes away. Unlike herpes, chlamydia does not stay in your system for life. However, chlamydia can come back after treatment if you contract the infection again. Antibiotics do not provide protection going forward and will only treat current infections. You should take adequate precautionary measures to protect yourself. We recommend carrying out a chlamydia test each time you have a new sexual partner.
