Your body has an allergic reaction when it is exposed to an allergen and perceived
it as harmful. People are triggered by different allergens, so what triggers
you might not trigger someone else. Common allergens include food, such as nuts,
eggs, shellfish and dairy products, as well as certain medications and dust.
Depending on the severity of your allergy, you may experience an itchy rash, itchy
or watery eyes, nasal congestion, hives, vomiting or stomach pain. Over-the-counter
antihistamines can alleviate many of the symptoms of mild allergic reactions.
If you suspect someone is having a severe allergic reaction, call an ambulance
immediately. Ask if they carry an EpiPen and, if they do, inject it into their
thigh. Lie them down and turn them on their side if they vomit or cough up blood.
Perform CPR if they stop breathing.
