Even though you have been treated and cured for Chlamydia once, you absolutely CAN get re-infected. Both you and your sexual partner(s) must get treated at the same time so you don’t re-infect each other. The best way to avoid getting a sexually transmitted infection is NOT to have sex. If you do decide to have sex, make sure your partner uses condoms 100% of the time to lower your risk of getting STIs (sexually transmitted infections). It’s important that you get treated early so that more serious health problems don’t occur. Your health care provider will decide which medicine is right for you. Remember to take ALL of the medicine as prescribed, even if the symptoms go away. This is because the infection can still be in your body.
