Lactobacillus vaginalis is mainly used clinically to regulate the normal flora in the vagina. By restoring the normal flora in the vagina, the local resistance will be enhanced, so vaginal inflammation can be prevented. It is relatively better to adjust with Lactobacillus after the age-related vaginitis is cured. It is recommended that when adjusting the vaginal flora with Lactobacillus, you should not take other types of antibiotics. If you take antibiotics, they will also kill the Lactobacillus, which will reduce the efficacy of the drug, so you should not take antibiotics orally or use them intravenously. In addition, it is recommended to use the medicine only under the guidance of a doctor. If there is acute inflammation in the vagina, it should be treated with antibiotics first, and after the inflammation is controlled, the local resistance of the vagina should be improved and then treated with lactobacillus.
