If vulvar itching occurs at night, if there is not much vaginal discharge and there is no labia minora or labia majora redness, it is often due to dermatitis of the vulva. In the perineum you can see rougher skin with local flushing or there will be small red papules. It is recommended to apply Paregoric Pine ointment or Mometasone ointment to the area for treatment 3-4 times a day. If symptomatic, this symptom will disappear in about 3 days. If the symptoms cannot be relieved clinically after 3 days of medication, you must go to the hospital for appropriate examination, mainly to understand the condition of the vulva. It is recommended to do routine laboratory tests of the leucorrhoea to exclude vulvar itching caused by secretions stimulated by vaginal pathogenic bacterial infections.
