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)
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.
