Women who have bacterial vaginosis often experience significant itching in the vulva, so it is necessary to choose effective medications for relief. After testing the vaginal discharge and confirming it is bacterial vaginosis, one should choose Metronidazole Vaginal Effervescent Tablets, which are a specific medication for treating this condition. Moreover, after the treatment is finished, it is advisable to continue using Lactobacillus Vaginal Capsules as vaginal medication. The occurrence of bacterial vaginosis in women, besides being caused by bacterial infections, is also related to the imbalance of vaginal flora. This happens when there is a low amount of Lactobacillus, which is unable to maintain the vaginal environment's acidity, leading to the growth of some opportunistic pathogens and inducing bacterial vaginitis. Therefore, after treatment, women need to use Lactobacillus Vaginal Capsules to prevent recurrence and should avoid frequent vaginal douching, which can lead to a significant loss of vaginal lactobacilli. (Medication use should be conducted under the guidance of a physician.)
