Urticaria, commonly known as hives is a common itchy rash, causing weals and swelling. If your hives last less than 6 weeks, usually hours to days, this is classified as acute. When lasting longer than 6 weeks with episodic or daily weals, it is categorised as chronic.
1 in 5 people experience an episode of acute urticaria (short term hives) during there lifetime. Hives occur when immune cells (mast cells) rouse under the skin, releasing histamine into the affected area. This causes an adverse reaction.

All dermatologists at the Queensland Institute of Dermatology have experience in treating this condition. Your specialist will investigate the cause of your hives with questions to determine obvious triggers and a determined path for treatment in your consultation. If a trigger is identified, avoidance is recommended. If no trigger is identified, hives are often treated with regular antihistamines. Due to hives' spontaneous nature, they may resolve on their own with no intervening treatment needed.
