How long does shingles last?
Last updated September 3, 2026.
The rash scabs over in 7 to 10 days and clears within 2 to 4 weeks, per the CDC - but the number that matters is 72 hours. Antivirals started within three days of the rash shorten the illness and lower the risk of postherpetic neuralgia, the nerve pain that can outlast the skin by months and is the most common complication. Rash near the eye is a same-day emergency.
What to do
- Call the day the rash appears. The 72-hour antiviral window closes fast.
- Do not scratch. Keep the rash clean and covered; loose clothing beats friction.
- Protect the vulnerable around you. Cover the rash around pregnant people, newborns, and the immunocompromised until it scabs.
- Get the vaccine at 50-plus. It prevents shingles and the long nerve pain, even after a prior episode.
