Allergic ReactionAn allergic reaction is an overreaction to a harmless substance. Symptoms and signs of an allergic reaction include hives, rashes, swelling, itching, wheezing, nausea, and even anaphylactic shock in severe reactions. Treatment involves avoiding triggers, taking oral antihistamines, applying anti-inflammatory steroid creams, and using an EpiPen.
Hives and AngioedemaHives are a sudden allergic skin reaction. Hives are raised reddish bumps that cause severe itching. Angioedema is similar to hives but the welts are larger and involve a deeper layer in the skin.

Severe reactions should be treated by a health care professional.
