Urticaria is very common, especially in people who have experienced other allergic reactions.
Many substances, called allergens, can trigger the allergic response.
Common allergens include
- Foods (such as berries, fish, nuts, eggs and milk)
- Animal dander (especially from cats)
- Insect bites
Signs & Symptoms
- Red or skin colored eruptions with clearly defined edges
- Sudden onset
- Rapid resolution
- Eruptions enlarge, spread, or join together to form large flat raised areas
- Eruptions change shape, disappear and reappear within minutes or hours
The best treatment for urticaria is to find and remove the cause.
Antihistamines are usually prescribed to provide relief.
