Most of the itching and redness in the vulva is caused by inflammation, so you can use topical dehumidifying and anti-itching lotion, or compound cypress lotion, Baian lotion, Chuanbao lotion, etc. to wash the vulva locally. Topical ointments such as nifurtimox vaginal ointment can be applied to relieve the symptoms. However, it is best to determine the cause of the redness and itching before applying the right medication. You can go to the hospital to check the white belt routine, or vaginal secretions of mycoplasma, chlamydia and so on, to determine the specific cause of vulvar itching, redness and swelling, and then use the right medicine. If it is bacterial, you can use metronidazole suppositories with the above mentioned creams, if it is mycotic, you can directly use Mecampa suppositories or Nifurtal vaginal ointment.
