For trichomoniasis, the main treatment method is medication, including local and systemic vaginal medication. In principle, attention should be paid to the treatment of both men and women and regular follow-up: 1. Before using the medication, the pH of the vagina should be changed and the vagina should be washed with acidic lotion such as lactic acid or acetic acid, which can reduce the foul-smelling vaginal discharge. During the treatment period, attention should be paid to avoid drinking alcohol, and breastfeeding women should suspend breastfeeding to reduce the impact on the baby. Even if only women visit the clinic, both partners should be treated at the same time to ensure the effectiveness of the treatment. 2. After treatment, the vaginal discharge should be rechecked after each menstrual period, and a negative result for three consecutive times means cure.
