Trichomonas infection in women results in trichomonal vaginitis, which is treatable and curable. The primary treatment for trichomonal vaginitis involves oral intake of metronidazole or tinidazole, and metronidazole can also be placed inside the vagina. However, during treatment, both male and female partners must undergo treatment simultaneously, as this disease is mostly transmitted through sexual intercourse. Therefore, if a woman has trichomonas, it is very likely that the male partner also has it. If the male does not receive treatment, he may re-infect the female during subsequent sexual activities. Thus, thorough treatment can only be achieved after both partners are treated. (Specific medications should be taken under the guidance of a physician.)
