Urticaria, commonly known as hives, manifests as itchy rashes characterised by redness and skin swelling, often resembling mosquito bites of varying sizes.


When hives occur around loose tissue, such as the eyes or lips, leading to swelling in these areas, the condition is known as angioedema. 

Examples of angioedema
Urticaria can be categorised into acute and chronic.
- Acute urticaria: The most common form in children, lasts less than six weeks, with fluctuations in size and location of the rashes.
- Chronic urticaria: Persists for over six weeks and is seen in both children and adults.
Urticaria is a common condition that affects up to 20% of people at some point in their lives1. Chronic urticaria is most commonly caused by the immune system, usually resolving over time. However, it may take 6 months or longer for the condition to be resolved.
