When are antibiotics recommended for trichomoniasis?

Trichomoniasis is caused by a parasite and can affect the vagina, cervix, or penis. Some people have no symptoms; others notice irritation, soreness, discomfort when urinating, or a change in vaginal discharge or smell. A clinician may use a swab or another test to confirm the infection. The medicine prescribed is designed to clear the parasite, and treatment of current sexual partners is important because infection can pass between partners even when symptoms are absent.

Take the prescribed medicine exactly as directed and tell the clinician about pregnancy, breastfeeding, allergies, or other medicines. Avoid sexual contact until you and your partner or partners have completed treatment and symptoms have settled as advised. Do not use leftover medicine or assume that a product for thrush will treat trichomoniasis. Arrange review if discharge, irritation, or urinary discomfort continues after treatment.

Seek prompt medical care for pelvic pain, fever, pain during pregnancy, bleeding that is unusual for you, or symptoms that are getting worse. Emergency help is needed for severe pain, fainting, confusion, heavy bleeding, or difficulty breathing, because these signs may point to another or more serious problem.

Ask which test confirmed the infection, whether partners need treatment, when sexual contact can resume, whether repeat testing is advised, and how to manage symptoms while the medicine takes effect.
