What should you know about green discharge trichomoniasis?

Trichomoniasis is caused by a parasite and may cause yellow-green or green discharge, an unusual smell, vaginal or vulval itching, burning, soreness, or discomfort when passing urine or having sex. Some people have no symptoms. Other infections and non-infectious changes can also alter discharge, so colour cannot identify the cause on its own.

A healthcare professional may take a vaginal sample or use another approved test. Tell them about pregnancy, recent antibiotics, new or multiple partners, pelvic pain, bleeding, and any medicine allergies so the assessment is appropriate.

Arrange testing rather than self-treating with leftover medicine or scented washes. If trichomoniasis is confirmed, take the prescribed treatment exactly as directed and ask how sexual partners should be tested or treated. Avoid sex until the clinician says it is appropriate, because reinfection can occur when partners are not managed together.

Use plain water or a gentle unscented cleanser externally and avoid douching. A page about vaginal discharge or vaginal itching can help you compare symptoms while you arrange care.

Seek prompt medical care for lower abdominal or pelvic pain, fever, pain during sex, bleeding after sex or between periods, or pregnancy with unusual discharge. Urgent assessment is needed for severe pain, faintness, vomiting, or feeling very unwell. These symptoms can signal a different or more extensive pelvic problem.

Ask which tests are needed, when results will be available, whether other infections should be checked, and when sex can safely resume. Ask whether partners need treatment, how to prevent reinfection, and what to do if symptoms remain after medicine.
