Allergies: When it’s An Emergency
Get to know the Pharmacist at Walmart
What are severe allergic reactions?
A severe allergic reaction is when the body’s immune system reacts badly to a substance that is usually harmless to most people. We call this substance an allergy trigger. A severe allergic reaction can occur within minutes to several hours after you come in contact with the trigger.
Some of the symptoms of a severe allergic reaction can be life threatening. For example, if your throat swells or airways become blocked you would be unable to breathe. Another example, is a sudden drop in blood pressure, which can make you feel dizzy, weak and faint, or make you pass out.

After you have taken your epinephrine go to the nearest emergency medical facility immediately, even if you feel much better. A health care professional will be able to determine whether you need further care.
