Women with yellowish leucorrhea and fishy odor are not advised to take medication blindly, but should be treated with oral medication under medical supervision after examining the cause. You can use drugs like metronidazole and ornidazole, which are mainly for bacterial or trichomonas inflammatory vaginitis, and cephalosporins for gonococcal vaginitis. You should also pay attention to the hygiene and cleanliness of your genital area, change your underwear regularly, and suspend sexual intercourse to avoid cross-infection. Before taking the medication, it is recommended to go to the local regular hospital for gynecological examination and routine examination of the white belt, and then choose the appropriate medication for treatment.
