Several antiviral medicines—acyclovir, valacyclovir, and famciclovir—are available to treat shingles. These medicines will help shorten the length and severity of the illness. But to be effective, they must be started as soon as possible after the rash appears. Thus, people who have or think they might have shingles should call their healthcare provider as soon as possible to discuss treatment options. Analgesics (pain medicine) may help relieve the pain caused by shingles. Wet compresses, calamine lotion, and colloidal oatmeal baths may help relieve some of the itching. | |||

Overview
Several antiviral medicines—acyclovir, valacyclovir, and famciclovir—are available to treat shingles. These medicines will help shorten the length and severity of the illness. But to be effective, they must be started as soon as possible after the rash appears. Thus, people who have or think they might have shingles should call their healthcare provider as soon as possible to discuss treatment options. Analgesics (pain medicine) may help relieve the pain caused by shingles. Wet compresses, calamine lotion, and colloidal oatmeal baths may help relieve some of the itching.
