Chlamydia is a sexually transmitted infection (STI). It is caused by a bacteria most often spread through vaginal, oral, or anal sex. You have an increased risk of chlamydia if you have another STI, such as gonorrhea. Your risk is also higher if you have more than 1 sex partner.



  • Antibiotics kill the bacteria that causes chlamydia. Take them as directed.
  • Take your medicine as directed. Call your healthcare provider if you think your medicine is not helping or if you have side effects. Tell him if you are allergic to any medicine. Keep a list of the medicines, vitamins, and herbs you take. Include the amounts, and when and why you take them. Bring the list or the pill bottles to follow-up visits. Carry your medicine list with you in case of an emergency.

Follow up with your healthcare provider as directed:

You may need to return regularly for tests. Write down your questions so you remember to ask them during your visits.


  • Keep your genital area clean and dry. Take showers instead of baths, and use unscented soap.
  • Do not douche unless your healthcare provider tells you to. Do not use feminine hygiene sprays or powders.
  • Tell your healthcare provider if you are pregnant.

Prevent the spread of chlamydia:

  • Wash your hands often. Use soap and water. Wash your hands after you use the bathroom. This helps prevent the infection from spreading to other parts of your body, such as your eyes.
  • Wear a latex condom to prevent chlamydia and other STDs. Use a new condom each time you have sex.
  • Tell your sex partners. Tell anyone you have had sex with in the last 3 months that you have chlamydia. They may also be infected and need treatment.
  • Do not have sex until you and your partner have taken all your antibiotics. Ask your healthcare provider when it is safe to have sex.

Contact your healthcare provider if:

  • Your signs or symptoms last longer than 1 week or get worse during treatment.
  • Your signs or symptoms return after treatment.
  • You have pain during sex.
  • You have questions or concerns about your condition or care.

Return to the emergency department if:

  • You have a fever or repeated vomiting.
  • You have severe abdominal pain.
