Chlamydia is one of the most common sexually transmitted infections (STIs) in the United States. Millions of new cases occur each year, and many people don’t realize they have it because symptoms are often mild—or completely absent. Left untreated, chlamydia can affect reproductive health and lead to serious complications.
Chlamydia is a bacterial sexually transmitted infection caused by Chlamydia trachomatis. It spreads through vaginal, anal, or oral sex and can infect people of any gender.
In women, chlamydia most commonly infects the cervix, urethra, rectum, or throat.
In men, it typically affects the urethra, rectum, or throat.
Chlamydia is primarily spread through unprotected sexual contact, including oral, vaginal, and anal sex. Barrier protection, such as condoms, significantly reduces the risk of transmission. Other forms of birth control (like pills or IUDs) do not protect against chlamydia.
Chlamydia can also be passed from a pregnant person to a baby during childbirth, potentially causing eye infections or pneumonia in newborns.
Chlamydia is curable, but untreated infections can lead to long-term health problems, especially in people with repeated or prolonged infections.
Potential complications include:
Pelvic inflammatory disease (PID)
Chronic pelvic pain
Ectopic pregnancy
Infertility
Epididymitis in men
Increased risk of acquiring or transmitting HIV
Because complications can occur even without symptoms, routine testing is essential.
When symptoms do occur, they may include:
Pain or burning with urination
Abnormal vaginal discharge
Bleeding between periods or after sex
Pelvic or lower abdominal pain
Rectal pain, discharge, or bleeding (if rectal infection)
Discharge from the penis
Burning or pain with urination
Testicular pain or swelling
Rectal pain, discharge, or bleeding (if rectal infection)
If the infection spreads, symptoms may include fever, nausea, or worsening abdominal pain.
Routine screening is recommended for:
Sexually active women under age 25
Anyone with new or multiple sexual partners
People with symptoms or known exposure
Testing is done using urine samples or swabs and is quick and highly accurate.
According to the CDC, the first-line treatment for uncomplicated chlamydia is:
Doxycycline 100 mg by mouth twice daily for 7 days
Alternative option (when doxycycline is not appropriate):
Azithromycin 1 g by mouth as a single dose
Most people are cured when antibiotics are taken exactly as prescribed.
Important treatment instructions:
Avoid sexual activity until 7 days after completing treatment
Sexual partners from the past 60 days should also be treated
Retesting is recommended 3 months after treatment to check for reinfection

The Call-On-Doc Guide to Chlamydia
As one of the most common STDs alongside bacterial vaginosis, chlamydia affects well over a million people in the United States alone. Having risen year-over-year, hopes of there being a decline in cases were curbed when the number of cases went from 1,579,885 in 2020 to 1,644,416 in 2021, but fortunately, chlamydia has not returned to pre-pandemic numbers. (1)
Formally known as Chlamydia trachomatis, the STD is most common in younger generations aged 15 to 24, with an estimated 1 in 20 sexually active young women in that age group having the condition. How chlamydia has become so prevalent can be easily explained, with the majority of those infected experiencing no symptoms and going without regular and recommended STD testing.

What is DoxyPEP?
Every year, it's estimated that around 374 million people are infected with curable sexually transmitted infections, most notably syphilis, gonorrhea, and chlamydia. (1) Just in the United States alone, the number of annual infections concerning the same STIs hovers between 1.5 million and just below 2 million. (2) Such rising numbers, alongside concerns for antibiotic resistance STDs, have driven the scientific and healthcare communities towards advancing new methods of cures and spread prevention. That’s where the recent development of DoxyPEP has made such an impact on doctors and patients alike.
Designed to function similarly to a morning-after pill, DoxyPEP is an oral antibiotic that has proven effective against immediate exposure to bacterial sexually transmitted diseases. Most effective if taken within 24 hours of exposure, DoxyPEP is also known to reduce bacterial STDs if taken within 72 hours.
