What medication should be taken for vaginitis?

Patient's question:

Another recurrence, what kind of help do you want: May I ask what kind of medicine I should take to this condition. How many courses of treatment do I need to take

Doctor's answer:

Consider bacterial vaginosis. Bacterial vaginosis is a disease caused by an imbalance in the vaginal ecosystem, where Gardnerella vaginalis and anaerobic bacteria increase while Lactobacillus decreases. It can be treated with oral medications such as metronidazole, tetracycline, and clindamycin.
Vaginal douching: A 1% lactic acid or acetic acid solution can be used for vaginal douching to restore the normal physiological environment and inhibit bacterial growth. During treatment, sexual activity should be avoided, plenty of water should be consumed, and spicy, cold, or other irritating foods should not be eaten.
