What causes vaginal dryness and itching after menstruation?

The term "below" usually refers to the vulva. Dryness and itching of the vulva after menstruation may be caused by factors such as an allergic reaction to sanitary pads, eczema, or vaginitis. It is recommended to obtain a clear diagnosis and receive treatment under a doctor's guidance.

1. Allergy to sanitary pads

During menstruation, using low-quality sanitary pads may trigger an allergic reaction in the vulvar area, leading to dryness and itching. It is advised to promptly change the sanitary pad and apply topical medications such as erythromycin ointment, tacrolimus ointment, or triamcinolone acetonide-nystatin cream to alleviate symptoms.

2. Eczema

If sanitary pads are not changed frequently during menstruation, the vulvar area may become excessively warm and moist, which can lead to eczema and cause itching. Under medical guidance, consider using anti-inflammatory, antipruritic, and antiallergic treatments such as hydrocortisone butyrate cream, mometasone furoate cream, or cyproheptadine hydrochloride cream.

3. Vaginitis

During menstruation, the body's immunity is relatively low. If infected with bacteria or viruses at this time, inflammatory reactions in the vagina may occur, resulting in itching. Under medical supervision, treatment options include metronidazole suppositories, tinidazole suppositories, or miconazole nitrate cream.

Besides the above causes, conditions such as lichen sclerosus may also be responsible.
