Chlamydia is a type of sexually transmitted infection (STI).
It is possible to get chlamydia in the throat after unprotected oral sex with a person infected with chlamydia.
Seek medical care for treatment if you have symptoms similar to strep throat after participating in oral sex.
When it comes to avoiding sexually transmitted infections (STIs), some people think oral sex is safer than intercourse. But several STIs—such as chlamydia, gonorrhea, and syphilis—can spread through oral sex. In many cases, chlamydia is curable with antibiotics, however an untreated chlamydia infection can result in serious health problems, including ectopic pregnancy and infertility.
This article discusses the possibility of getting chlamydia in the throat, what it may look like, and other symptoms. It also talks about diagnosis and treatment options, how chlamydia spreads, and when it’s time to seek medical care.
Can You Get Chlamydia in the Throat?
It is possible to get chlamydia in your throat when you have unprotected oral sex with a person who is infected with chlamydia.
Possible routes of getting chlamydia in the throat include:
- Giving oral sex to a person with an infected penis
- Giving oral sex to a person with an infected vagina or urinary tract
- Giving oral sex to a person with an infected rectum
What Does Chlamydia in the Throat Look Like?
In some people, a chlamydia throat infection doesn’t cause any symptoms, however it can still spread to others. Some people experience symptoms similar to a strep throat infection.
You may have a sore throat and notice that your mouth and throat are more red than usual. Some people also get white spots on their tonsils or back of their throat. In some cases, sores form in the mouth or around the lips. Your tongue may also feel more bumpy.
Symptoms of Chlamydia in the Throat
Common symptoms of oral chlamydia include:
- Sore throat
- Pain the mouth
- Redness in the mouth or throat
- Mouth sores
- Sores around the lips
- Dental problems
- Swollen lymph nodes
- Bumps on the tongue
- White spots in the back of the throat or tonsils
Symptoms of a genital chlamydia infection include:
- Pain or burning during urination
- Frequent urination
- Pain during sexual activity
- Pain or swelling of the testicles
- Itching or burning
- Rectal pain
- Unusual discharge from the penis or vagina, including bloody discharge
Keep in mind that chlamydia symptoms may not surface right away. They usually appear 1-3 weeks after initial sexual contact with an infected individual. Even if a person with chlamydia doesn’t have symptoms, they can still spread the infection to others.
How Is Chlamydia Diagnosed?
Whether you have symptoms of a chlamydia infection in your throat or genitals, it is important to see a healthcare provider as soon as possible. Many tests can screen for chlamydia, but testing for throat chlamydia isn’t usually part of standard STI screening. Tell your medical provider if you’re experiencing symptoms in your throat or are worried about an infection after giving oral sex.
If your medical provider suspects chlamydia in the throat, they’ll ask about your symptoms and sexual contact. They may then swab your throat and send the sample to a lab to test for chlamydia. It’s also possible that you’ll have a general STD test, which may involve a urine sample, blood test, or cheek swab. If you test positive for any STI, make sure to tell your sexual partners so they can take necessary precautions.
Healthcare providers treat throat chlamydia infections with antibiotics such as azithromycin or doxycycline. Antibiotics work by slowing or stopping bacterial growth, which cures the infection. If you are diagnosed with chlamydia of the throat, wait to have oral sex or sexual intercourse until you finish your prescribed dose and your symptoms have completely resolved.
Even if your symptoms improve or go away, make sure to finish the entire course of antibiotics. Stopping early could cause the infection to come back. While antibiotic treatment may cure a current infection, it is possible to get chlamydia again. The recurrence rate of chlamydia is particularly high, so it’s important to take action to prevent future infections.
Preventing throat chlamydia
Because throat chlamydia spreads through contact during oral sex, practice safe sex by using a condom or dental dam.
Other ways to prevent the spread of chlamydia include:
- Avoiding sexual contact if you have sores in your mouth
- Using latex or plastic condoms or a sexual barrier
- Routinely getting checked for STIs
- Encouraging your partner to have regular STI checks
If you have any symptoms of chlamydia or any other STI, it’s best to avoid sexual contact until you receive and finish any treatment. You cannot get chlamydia from contact with toilet seats, sharing clothes or towels, or hugging.
Risks of Chlamydia in the Throat
Along with potentially uncomfortable symptoms, chlamydia carries a risk of other medical complications:
- Infertility in women
- Preterm delivery in pregnant women
- Ectopic pregnancy (a pregnancy that implants outside of the uterus)
- Infections in newborn babies from an infected parent
- Inflammation in the upper genital tract
- Prostate gland infection
- Pelvic inflammatory disease (an infection of the uterus and fallopian tubes that causes pelvic pain and fever)
- Reactive arthritis, also known as Reiter’s syndrome, a type of inflammatory arthritis
If you have chlamydia and think you may be experiencing any of these complications, seek emergency medical care right away. Some chlamydia-related medical issues can be irreversible without proper treatment.
When to See a Doctor
If left untreated, throat chlamydia can result in significant health complications. If you have strep throat-like symptoms after giving oral sex, seek medical care right away, especially if you’re pregnant. A healthcare provider can test you for chlamydia and other STIs and also rule out other infections.
