Itching of the vulva occurs during menstruation. It is recommended to wash the vulva twice with 30% cleanser and to apply topical Pirexone ointment. This condition is mostly due to itching caused by local skin inflammation during menstruation when the sanitary napkin is not breathable. It is advisable to change sanitary napkins regularly and use cotton sanitary napkins instead of mesh ones. You should pay attention to your diet, do not eat spicy and sour food and stimulating food, and it is recommended to change underwear regularly to keep the local clean. Ensure sufficient sleep, eat more fresh fruits and vegetables, and take vitamins to help relieve the symptoms of vulvar itching as soon as possible.
