Chlamydia Infection in Male Teens: Care Instructions


Chlamydia is a bacterial infection that is spread through sexual contact. It can spread from one partner to another during vaginal, anal, or oral sex. Most people who have chlamydia don't have symptoms. But they can still infect their sex partners.

Treatment is important. If chlamydia isn't treated, it can lead to another kind of infection that causes pain and burning when you urinate (urethritis).

It's easy to get chlamydia again. Condoms can help prevent infections. Not having sex is the best way to prevent any sexually transmitted infection.

Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse call line if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.

How can you care for yourself at home?

  • Chlamydia often is treated with a single dose of antibiotics in the doctor's office. If your doctor prescribed antibiotics to take at home, take them as directed. Do not stop taking them just because you feel better. You need to take the full course of antibiotics.
  • Do not have sex with anyone while you are being treated. If your treatment is a single dose of antibiotics, wait at least 7 days after you take the dose before you have sex. Even if you use a condom, you and your partner may pass the infection back and forth.
  • Make sure to tell your sex partner or partners that you have chlamydia. They should get treated, even if they do not have symptoms.
  • Your doctor may have done tests for other STIs.
  • Your doctor may advise you to be tested again for chlamydia in 3 or 4 months.

How can you prevent it?

It's easier to prevent an STI than it is to treat one.

  • Limit your sex partners. The safest sex is with one partner who has sex only with you.
  • Talk with your partner or partners about STIs before having sex. Find out if they are at risk for an STI. It's possible to have an STI and not know it.
  • Wait to have sex with a new partner until you've each been tested.
  • Don't have sex if you have symptoms of an infection or if you're being treated for an STI.
  • Use a condom (a male or female condom) every time you have sex.
  • Don't feel pressure to have sex. It's okay to say "no" anytime you want to stop.
  • Make sure you feel safe with your partner or partners. If you don't, talk with an adult you trust.

Vaccines are available for some STIs, such as HPV. Ask your doctor for more information.

When should you call for help?

Call 911 anytime you think you may need emergency care. For example, call if:

  • You have sudden, severe pain in your belly or pelvis.

  • You have new belly or pelvic pain.
  • You have a fever.
  • You have new or increased burning or pain with urination, or you cannot urinate.
  • You have pain, swelling, or tenderness in your scrotum.

Watch closely for changes in your health, and be sure to contact your doctor or nurse call line if:

  • You have a discharge from your penis.
  • You think you may have been exposed to another STI.
  • Your symptoms get worse or have not improved within 1 week after you start treatment.
