Treatment for both pregnant and non-pregnant women is usually with metronidazole, by mouth once. Caution should be used in pregnancy, especially in the first trimester. Sexual partners, even if they have no symptoms, should also be treated. Single oral dose of nitroimidazole is sufficient to kill the parasites. For 95–97% of cases, infection is resolved after one dose of metronidazole. Studies suggest that 4–5% of trichomonas cases are resistant to metronidazole, which may account for some "repeat" cases. Without treatment,<unk>  can persist for months to years in women, and is thought to improve without treatment in men. Women living with HIV infection have better cure rates if treated for seven days rather than with one dose. Topical treatments are less effective than oral antibiotics due to Skene's gland and other genitourinary structures acting as a reservoir.
