The most important causes of acute urticaria are drugs, foods and infections.

Acute urticaria, which is more common in childhood, may be related to foods and infections.

In adulthood, among the causes of acute urticaria, food and infections, as well as drugs, have an important place. Acute urticaria can usually subside within 2-3 weeks.

Urticaria complaints may sometimes be the first complaint as a harbinger of allergic diseases, sometimes they may accompany other allergic diseases. During the course of allergic rhinitis and asthma caused by pollen allergies involving the respiratory tract, urticaria attacks can be seen in patients during the pollen season.

In particular, patients with urticaria are recommended to stay away from NSAI drug groups as pain relief.

Urticaria complaints may occur first in drug allergies, but later on, when the same drug is taken, more serious allergic reactions may develop. Therefore, it is necessary to diagnose acute urticaria and to reveal the underlying causes.

Urticaria plaques, especially chronic urticaria, can be a harbinger of a pre-existing disease or may occur during the course of the disease. Therefore, urticaria should be cared for and its causes should be investigated.
