Hives typically last from a few days up to a few weeks. Each individual hive usually fades within 24 hours, but new hives can continue to appear, making the overall episode last longer
. If hives persist for more than six weeks, they are classified as chronic hives, which can last for months or even years, often recurring frequently over time
. Chronic hives may eventually resolve on their own but can require medical treatment to manage symptoms
. In summary:
- Acute hives: Usually last a few days to a few weeks; individual hives last less than 24 hours.
- Chronic hives: Last longer than 6 weeks, sometimes months or years, with recurring episodes.
If hives last longer than a few weeks or are accompanied by severe symptoms like swelling of the face or difficulty breathing, medical attention should be sought promptly
