The reasons why mycotic vaginitis patients become more itchy with medication are as follows: 1. Mycotic vaginitis is caused by changes in the acidic environment of the vagina, and if no targeted medication is administered, the condition can worsen and become more itchy with medication; 2. When the immunity of the body decreases, if antibiotics are used in large doses at this time, the normal vaginal flora environment will be damaged, making the acidic environment of the vagina gradually become alkaline and become more itchy with medication. Therefore, if high doses of antibiotics are used and drugs that are not specifically for the treatment of mycosis vaginalis, the itchier the more drugs are used, so we must pay attention to the selection of drugs in the treatment, and if necessary, we need to go to the hospital.
