High Hives (Allergy)

Symptoms: 

The symptoms include:

  • Raised itchy bumps, either red or skin-colored
  • “Blanching” (when pressed, the center of a red hive turns white)
Tests to diagnose: 

A skin biopsy or blood tests are done to confirm that you had an allergic reaction

Treatment: 

Antihistamines (cetirizine, fexofenadine, loratadine) are usually prescribed to provide relief from symptoms. For severe hive or angioedema outbreaks, an injection of epinephrine or a steroid medication may be needed.
