Trichomoniasis symptoms and treatment

Trichomoniasis is a sexually transmitted infection caused by a parasite. When symptoms occur, they may include a change in discharge, an unusual smell, genital itching, soreness, burning when urinating, or discomfort during sex. A [Vaginal Discharge](/symptoms/vaginal-discharge/) or [Vaginal Itching](/symptoms/vaginal-itching/) page can help you describe what you notice, but symptoms alone cannot identify the cause.

A vaginal swab or urine sample may be used for testing. A breast lump is not relevant here: vaginal symptoms can have several explanations, so avoid treating yourself based only on appearance or discomfort.

Arrange a sexual-health or gynaecology appointment for testing. If the result is positive, take the prescribed oral medicine exactly as directed and finish the course. Avoid sex until treatment instructions say it is appropriate and current partners have been assessed, because untreated partners can pass the infection back.

Do not share leftover antibiotics or use vaginal products to mask the discharge. Ask whether you need testing for other sexually transmitted infections and whether a follow-up test is advised. Information about [Antibiotic Treatment for Pelvic Infection](/treatments/medical-gynaecology/antibiotic-treatment-for-pelvic-infection/) may explain how prescribed antimicrobial treatment is approached.

Seek prompt medical care for pelvic or lower-abdominal pain, fever, vomiting, pain during pregnancy, unusual bleeding, or feeling faint. These features may point to a different or more extensive problem and should not be managed by waiting for symptoms to settle.

If symptoms continue after treatment, return to the clinician rather than repeating medicine yourself. Tell them when treatment was taken and whether every partner was treated.

Which test will confirm the cause of my symptoms? Should my current or recent partners be tested and treated? When can we safely resume sex? Do I need screening for other infections or a repeat test?
