Myth: Reactions get worse each time you have one

Allergic reactions are unpredictable. When they occur, they can be the same, less severe than, or more severe than previous reactions. Additionally, a person with food allergies might not always experience the same symptoms of an allergic reaction (for example, an individual may have hives with one reaction, and vomiting with a subsequent reaction). The nature of a reaction depends on a person's level of allergy and how much of the allergy-causing food was ingested.
