The most common cause is dermatitis of the vulva, such as eczema of the vulva, which can cause itching of the vulva in addition to red papules. 2. Allergies due to certain medications, such as vaginal medications or oral medications, lead to allergic phenomena and drug rashes, which manifest as red dots on the vulva. 3. See red dots on the vulva caused by syphilis. Therefore, in this case, gynecological examination is recommended. 1. to find out whether the local skin of the vulva is rough and of the nature of a small papule. 2. to find out whether there is an increase in vaginal discharge and whether there is a recent history of vaginal plugs or oral medication. 3. to recommend serological screening for syphilis.
