High Hives (Allergy)


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


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.
