First-line treatment for trichomoniasis

Trichomoniasis is caused by a parasite and may cause vaginal discharge, irritation, itching, discomfort during sex, or burning when passing urine. Some people have no noticeable symptoms. A clinician may test a vaginal sample or urine before prescribing treatment. Take the medicine exactly as directed and tell the clinician about allergies, other medicines, liver problems, and pregnancy. Symptoms can improve before the infection has fully cleared, so completing the prescription matters. Vaginal Discharge and Vaginal Itching describe common symptoms but cannot confirm the cause on their own.

Tell current sexual partners so they can receive assessment and treatment. Avoid sex until you and your partners have completed treatment and a clinician says it is reasonable to resume; otherwise reinfection can occur. Use condoms consistently afterward to lower transmission risk. Return for review if symptoms continue, recur, or follow a new sexual exposure. Do not share leftover antibiotics or use treatment prescribed for someone else. Antibiotic Treatment for Pelvic Infection is a related treatment topic, but a clinician should choose medicine for your confirmed diagnosis.

Arrange prompt medical care for pelvic or lower abdominal pain, fever, vomiting, pain during pregnancy, bleeding after sex, or symptoms that rapidly worsen. Seek urgent help for severe pain, fainting, heavy bleeding, or feeling seriously unwell. These features may signal another infection or complication and should not be managed with self-treatment alone.

Ask which test confirmed the infection, whether partners need treatment, when sex can safely resume, whether repeat testing is advised, and what to do if symptoms remain after the prescription.
