Urticaria (Hives): Causes, Symptoms & Treatment in Australia

Urticaria, commonly known as hives, is a condition that causes raised, itchy welts on the skin. These welts can appear suddenly, change shape, and often come and go within hours.

In clinical practice, urticaria is something we see quite often. It can be short-lived (acute) or persist for weeks to months (chronic urticaria), and the experience can vary significantly between individuals.

While it can be uncomfortable and sometimes distressing, most cases are not dangerous — although identifying triggers and patterns can be important.

At Dermo Direct, dermatologists can assess suspected urticaria online and help guide appropriate management.

4. Specialist Treatments

For persistent or severe chronic urticaria, referral to a specialist may be recommended. This can include:
