Signs of an Allergic Reaction

Knowing the signs of an allergic reaction can help you seek medical attention quickly and prevent a potentially serious outcome. Your allergist, Surprise, AZ can then perform tests to determine the specific allergen and provide you with the ideal treatment plan.

  • Foods: Certain foods can trigger an allergic reaction, such as peanuts, shellfish, wheat, and dairy.
  • Insects: Stings or bites from certain insects may cause an allergic reaction, such as swelling, redness, and itching.
  • Medications: Even over-the-counter medications such as aspirin and ibuprofen can cause a reaction in some people.
  • Pollen: Environmental pollen from grass, trees, and other plants can trigger an allergic response.
  • Mold: Mold spores found in household dust can cause severe allergic reactions in many people.
