From the Guidelines
The recommended dose of doxycycline for treating chlamydia is 100 mg taken orally twice daily for 7 days. This regimen is considered the first-line treatment for uncomplicated chlamydial infections in non-pregnant adults, as outlined by the Centers for Disease Control and Prevention (CDC) 1. It's essential to take the full course of antibiotics even if symptoms improve before completion to ensure the infection is completely cleared. Doxycycline should be taken with a full glass of water, and patients should remain upright for at least 30 minutes after taking it to prevent esophageal irritation. Food doesn't significantly affect absorption, but taking it with food may reduce stomach upset. Patients should avoid dairy products, antacids, iron supplements, and calcium supplements within 2 hours of taking doxycycline as these can reduce absorption. During treatment, patients should abstain from sexual activity or use condoms consistently to prevent transmission, as recommended by the CDC 1. Doxycycline works by inhibiting bacterial protein synthesis, preventing the bacteria from reproducing and allowing the immune system to clear the infection. Side effects may include photosensitivity, so sun protection is advised during treatment.
Some key points to consider when treating chlamydia with doxycycline include:
- The importance of completing the full 7-day course of treatment, even if symptoms resolve before completion 1
- The need to abstain from sexual activity or use condoms consistently during treatment to prevent transmission 1
- The potential for side effects, such as photosensitivity, and the importance of sun protection during treatment
- The recommendation to avoid certain products, such as dairy products and antacids, that can reduce doxycycline absorption 1
It's also important to note that doxycycline is not the only treatment option for chlamydia, and other antibiotics, such as azithromycin, may be recommended in certain situations, such as pregnancy or allergy to doxycycline 1. However, the 100 mg twice daily for 7 days regimen of doxycycline remains a widely recommended and effective treatment option for uncomplicated chlamydial infections.
From the FDA Drug Label
Uncomplicated urethral, endocervical, or rectal infection in adults caused by Chlamydia trachomatis: 100 mg, by mouth, twice a day for 7 days. The recommended dose of doxycycline for treating chlamydia is:
- 100 mg, by mouth, twice a day for 7 days 2 Key points:

- The absorption of doxycycline is not markedly influenced by simultaneous ingestion of food or milk.
From the Research
Doxycycline Dose for Chlamydia
- The recommended dose of doxycycline for treating chlamydia is 100 mg, taken orally twice daily for 7 days 3, 4, 5, 6, 7.
- This dosage has been shown to be effective in treating urogenital and rectal chlamydia infections in various studies 4, 5, 6, 7.
- A 7-day course of doxycycline has been found to be superior to a single dose of azithromycin in treating rectal chlamydia infection among men who have sex with men 4, 7.
Efficacy of Doxycycline
- Doxycycline has been shown to have a high efficacy rate in treating chlamydia infections, with cure rates ranging from 96.9% to 100% 4, 5, 6, 7.
- The efficacy of doxycycline has been compared to azithromycin in several studies, with doxycycline generally showing higher cure rates 4, 6, 7.
Treatment Guidelines
- The Centers for Disease Control and Prevention (CDC) recommend doxycycline as a first-line treatment for chlamydia infections, with a dosage of 100 mg taken orally twice daily for 7 days 4, 5, 6, 7.
- Other treatment guidelines, such as those from the Infectious Diseases Society of America, also recommend doxycycline as a treatment option for chlamydia infections 7.
