@prasoon Treatment for acute urticaria includes non-sedating antihistamines taken regularly for several weeks.
Antihistamines, such as cetirizine or fexofenadine, help by blocking the effects of histamines and reducing the rash and stopping the itching.
Various antihistamines can be purchased in pharmacies or online.
Some antihistamines cause drowsiness, especially if the user also consumes alcohol. Some are not suitable during pregnancy unless prescribed by a doctor.
Patients with angioedema may need to see an allergist, an immunologist, or a dermatologist. Angioedema can cause potentially serious breathing difficulties.

If there is swelling of the tongue or lips, or if breathing becomes difficult, the doctor may prescribe an epinephrine auto-injector, for example, EpiPen, in case of emergencies.

Patients should avoid known triggers, if possible.
