There is currently no cure for shingles, but the rash usually clears up in 2–4 weeks. However, treatment can help manage it. If a person takes antiviral medication soon after the rash appears, it may shorten the duration of the infection and reduce the severity of symptoms.
Over-the-counter pain relief, wet compresses, calamine lotion, and lukewarm baths with colloidal oatmeal may help manage discomfort.
