Women are tested for bacterial vaginitis, mainly because of low body resistance, dysbiosis of vaginal flora, which increases leukocytes or pus cells, and infection caused by dysbiosis of flora due to long-term heavy use of antibiotics. Inflammation caused by bacterial infection becomes bacterial vaginitis, which is common in clinical practice. The main clinical manifestations of bacterial vaginitis are increased leucorrhea, yellowish-green color, odor, which may be accompanied by local redness and pain in vulva or vagina. If infected urinary system can appear frequent, urgent and painful urination. Women who have sex can choose metronidazole vaginal tablets or tinidazole suppositories to plug the vagina every night before bedtime for a week, which can be cured. If the leucorrhea is more, you can use douche solution to flush out the excessive leucorrhea and drug residue from the vagina before putting the pills, which will be more effective. For women who do not have sex, oral medication is the main choice. You can choose Ornidazole dispersible tablets or metronidazole tablets, which need to be taken for 5-7 days. If vulvar itching is serious, you can use erythromycin ointment to stop itching externally.
