The best treatment for urticaria is to identify and avoid the cause and any aggravating factor.
Doctors prescribe anti-histamines for immediate relief of symptoms.
Antihistamines, when taken orally, take about an hour or so to relieve a rash.
They work best if taken on a regular basic to prevent the eruption of urticaria. To avoid side-effects like drowsiness, heaviness, non-sedative antihistamines are often taken side by side.
Elimination diets are not of much help unless a particular food allergen is suspected
