I have shingles i'm on a antiviral antibiotic how long will it take for rash to go away?

Shingles: Rash begins to dry up in a week or two and may take a month to disappear completely.

Shingles: Most cases of shingles last 3 to 5 weeks. Usually 1 to 5 days after one experiences pain/burning in a specific area, a rash with blisters appears. This may take a week to 10 days to dry up & become crusty. Usually within a couple of weeks the scabs resolve. REF: https://www.nia.nih.gov/health/shingles#catch
