Causes

You are most likely to go into allergic shock after taking a drug or eating something you are allergic to, or after an insect sting. Allergic shock also can happen after skin contact with an allergen, such as latex. Under certain conditions, you can develop allergic shock while exercising.

Symptoms

Mild allergic reactions can include sniffling, sneezing, and watery eyes, almost like the symptoms of a cold. You may also have a mild rash. When you go into allergic shock, your whole body can be involved. Allergic shock can happen within 15 minutes of exposure to an allergen, so quick action is needed. Signs of allergic shock include:

• Choking or gasping for air
• Difficulty swallowing/lump in throat
• Extensive facial swelling
• Swelling of lips, tongue, or throat
• Dusky, bluish color of lips or nails
• Tight feeling in throat that persists or progresses
• Trouble speaking or husky voice
• Persistent coughing and difficulty breathing
• Cool, clammy, pale skin
• Significant weakness or dizziness
• Drowsiness, confusion, or loss of consciousness
• Seizures

Prevention

• Avoid foods, chemicals, drugs, and other substances that have caused allergic reactions.
• Wear a medical alert bracelet that warns of your allergy and tells what to do in an emergency. Inform your friends and co-workers of your allergies.
• Tell your doctor and dentist about any medication allergies you have. This includes prescription and over-the-counter medications.
• Check labels before taking over-the-counter medication or eating foods if you have medication or food allergies.

First Aid

• Some people with severe allergies carry an EPIPEN, a syringe that injects a medication that makes the reaction less severe. If the person shows symptoms of a severe allergic reaction, use the EPIPEN immediately.
• A double dose of Benadryl can be given to help control the reaction if no EPIPEN is available.
• Call 911.
