If you have trichomonal vaginitis, there will be an increase in vaginal discharge and itching in the vulva. If not treated thoroughly, it may recur frequently. It is recommended for trichomonal vaginitis to purchase some cleansing solution to wash the vulva and use metronidazole vaginal tablets to reduce inflammation and treat the condition, continuing for seven to ten days as one treatment course. If the symptoms are severe, it might be necessary to undergo three treatment courses, and the sexual partner should also be treated simultaneously. During the treatment period, refrain from sexual intercourse to prevent cross-infection.
