A positive test for hydrogen peroxide indicates inflammation of the vagina. It is recommended to use local medication but not to insert medication into the vagina if the woman has no history of sexual intercourse. If you are sexually active or married, it is recommended to insert metronidazole pessary, compound metronidazole pessary or compound sea buckthorn seed oil pessary into the vagina for one week. Do not have sexual intercourse during the medication period, and it is also recommended to avoid eating spicy and sour food and stimulating food. It is recommended that you go to the hospital about 3 days after stopping the medication to recheck the leucorrhea, and if the hydrogen peroxide has turned negative, you can stop using the medication. Women are advised to pay special attention to sexual and menstrual hygiene in their daily life so as to reduce the possibility of vaginal inflammatory infections.
