Allergic Reactions

An allergic reaction is an abnormal response to an otherwise harmless substance. These substances are known as allergens. Allergic reactions can be caused from substances that are inhaled, ingested, absorbed or injected.

Some common causes of allergic reactions can include:

  • Pet dander
  • Insect stings
  • Some foods including nuts.
  • Certain medications
  • Some plants, pollens, or moulds.

Symptoms of a mild to moderate allergic reaction may include:

  • Hives (itchy red spots on the skin)
  • Rash
  • Nasal congestion
  • Watery eyes
  • Red, itchy skin and/or welts
  • Tingling to the lips or mouth
  • Swelling to face and or eyes.

A severe allergic reaction can develop within seconds after coming into contact with an allergen. These types of reactions are known as Anaphylaxis.
