Acute Urticaria and Chronic Urticaria: What Is the Difference?
How long it lasts shapes the approach to treatment, and the two focus on different things.
Main differences
- Acute: shorter episodes, usually easing within days to weeks, often linked to infection, food or medicine
- Chronic: weals keep coming back for more than six weeks, triggers are often hard to find, and a systematic check is needed
Similar signs but a different approach
Both cause recurring weals and itching, but with acute episodes the focus is more on finding recent triggers and dealing with them; with chronic urticaria (hives) the focus is more on using medicine regularly to control symptoms, gradually checking for possible underlying factors, and keeping up long-term follow-up with a doctor.
Everyday care
Keep a record of how often episodes happen and how the weals change, and avoid scratching, hot water washing and alcohol-based skin products; use medicine regularly as your doctor advises, and do not stop or increase the dose on your own. If symptoms keep getting worse, or you have trouble breathing or similar signs, see a doctor right away.
