The most important thing is to try to not touch or scratch the rash. This can spread the rash to other parts of the body, increase the chance of spreading the virus to others, and possibly cause open lesions to become infected by bacteria. If you do accidentally touch the rash, wash your hands with soap and water and avoid touching sensitive areas like your eyes, nose, mouth, genitals and rectum (butthole).
Topical benzocaine/lidocaine gels can be used for temporary relief. Oral antihistamines such as Benadryl and topical creams such as calamine lotion or petroleum jelly may help with itching.
Soaking in a warm bath (using oatmeal or other over-the-counter bath products for itchy skin) may offer some relief to the dry, itchy sensations that can come with the rash.
People who have the rash in or around their anus (butthole) or genitals (penis, testicles, labia, vagina), or perineum (taint) may also benefit from a sitz-bath. A sitz bath is a round, shallow basin that can be purchased online or at a pharmacy. Most fit over the rim of a toilet but can also be placed in a bathtub. There is also the option to sit in a bathtub with shallow water. Your healthcare provider may prescribe medication like povidone-iodine or other products to be added to the water in a sitz bath. Adding Epsom salt, vinegar, or baking soda to the water can be soothing.
