    What are the treatments for Shingles ?
    ### Response:
    The severity and duration of an attack of shingles can be significantly reduced by immediate treatment with antiviral drugs, which include acyclovir, valcyclovir, or famcyclovir. Antiviral drugs may also help stave off the painful after-effects of shingles known as postherpetic neuralgia.
