The most effective treatment for vulvar itching is to wash the vulva and then apply topical Parasol ointment or mometasone ointment, which will have an immediate effect. The cause of vulvar itching must be investigated clinically. If the itching is caused by vulvar dermatitis, the treatment will achieve the goal of curing. If it is due to vulvovaginal pseudomycosis or trichomonas vaginitis, or mycoplasma, chlamydia infection caused by vulvovaginal itching, topical application of Piperisone or mometasone can only alleviate the symptoms, treating the symptoms but not the root cause. It is necessary to give targeted medication for the pathogenic bacteria of the vaginal infection in order to achieve the desired effect, so that the symptoms of vulvar itching can be cured as soon as possible.
