If vulvar itching occurs with sanitary napkins, it is most likely due to sanitary napkin allergy. It is recommended to use cotton sanitary napkins instead of mesh ones, and it is also recommended to change sanitary napkins regularly so as to avoid pathogenic bacteria from multiplying and causing itching of the vulva. If the vulva itching occurs change the sanitary napkin for another brand of sanitary napkin and apply mometasone ointment to the itching area for effective anti-allergy treatment. It is recommended that if the itching is not relieved by three consecutive days of medication, you can go to the hospital for an examination to rule out the vulva itching caused by bacterial infection. And it is recommended that when itching clinically, you should not eat sour and spicy as well as stimulating foods, and you should not drink alcohol. It is recommended to develop good habits and ensure sufficient sleep to help the disease heal as soon as possible.
