Age-related vaginitis occurs mainly in post-menopausal women due to a decrease in local resistance of the vagina caused by a decrease in estrogen levels, which causes bacterial infections and leads to inflammation. The main treatment is: first, to increase the resistance of the vagina through estrogen supplementation. For example, ointments containing estrogen can be applied, such as estriol ointment 1-2 times a day for 14 days, or oral medication, such as oral tibolone, 2.5 mg once a day. Secondly, you can use antibacterial agent vaginally, using norfloxacin 100 mg, put it into the deep vagina once a day for 7-10 days as a course of treatment. You can use Chinese herbal medicine’s Povidon suppositories, and clinically, metronidazole suppositories are also commonly used, with one tablet placed in the vagina every night for 7-10 days. The treatment of senile vaginitis by estrogen supplementation and the application of antibacterial agents is very effective.
