In brief: A week

Prompt treatment (within 72 hours of onset) with an antiviral such as valacyclovir or Famciclovir will resolve most cases of shingles within a week.
By "resolve" i mean most of the pain and inflammation will be gone, and no new blisters will be forming; complete resolution takes longer. A longer course may mean an underlying problem with the immune system, and your doctor will run some tests.
