If itching or even redness occurs, it means that the patient may be allergic to the pessary, in which case it is important to stop using the pessary. If vaginal inflammation is present, you can change to other medications for treatment. You can also wash your vulva with water and, if necessary, use a douche to rinse out the remaining medication in the vagina, which can often be relieved after the above treatment. However, if the symptoms are still severe, oral anti-allergy medications such as loratadine can be given to relieve the symptoms, depending on the severity of the discomfort.
