Chlamydia trachomatis is treated with antibiotics. You may receive a one-time dose, or you may need to take the medication daily or multiple times a day for five to 10 days.
In most cases, the infection resolves within one to two weeks. During that time, you should abstain from sex. Your sexual partner or partners also need treatment even if they have no signs or symptoms. Otherwise, the infection can be passed back and forth between sexual partners.
Having chlamydia or having been treated for it in the past provides no immunity against reinfection in the future.
