Urgent Evaluation of Purulent Vaginal Discharge in Levonorgestrel IUD Users

Guideline Recommendations (CDC, 2024)

The 2024 CDC contraception guidelines state that women with active purulent cervicitis or a confirmed chlamydia/gonorrhea infection should not have a levonorgestrel intrauterine device in place. 1
When abnormal vaginal symptoms occur in IUD users, the CDC recommends promptly evaluating for an underlying sexually transmitted infection (STI) or other genital tract infection. [1][2]
Patients should be seen within 24–48 hours for assessment of possible infection. [1][2]
A complete pelvic examination, including inspection of the cervical os, is advised as the first step in the urgent work‑up. 1
Cervical specimens for nucleic‑acid amplification testing for Chlamydia trachomatis and Neisseria gonorrhoeae should be obtained. 1

Discharge described as “larger than a grape” occurring 2–3 times daily exceeds the volume of normal vaginal secretions and is a red‑flag sign. 1
A yellow‑green coloration of the discharge strongly suggests a bacterial infection or cervicitis. 1
Onset of symptoms within the past 2 days warrants rapid evaluation because early infection can progress quickly. 1

Lower abdominal (pelvic) pain on examination is a key symptom to document. 1
Fever ≥ 38 °C is an objective sign that raises concern for ascending pelvic infection. 2

Do not delay care; untreated pelvic infection can jeopardize future fertility. 1
Do not assume the discharge is a normal adjustment to the IUD; purulent discharge always requires investigation. 1
Do not remove the IUD before medical evaluation unless a clinician determines it is necessary after infection has been excluded. [1][2]
