Anaphylaxis is a potentially life-threatening allergic reaction with rapid onset of symptoms. Anaphylaxis usually occurs in people after they are exposed to a substance they are severely allergic to such as foods, medications, and insect stings. It has been estimated that up to 15% of the population is at risk for anaphylaxis. If you or someone near you experiences anaphylaxis, call 911 or seek emergency medical care. Check to see if the person carries an epinephrine (adrenalin) shot (EpiPen, Twinject) and inject it into the thigh immediately. To save time, the shot can be injected through clothing. The person should still receive medical care immediately even if he or she received a shot.
Your immune system usually fights germs to keep you healthy. If you have allergies, your immune system overreacts to fight ordinary substances that normally are not harmful, such as pollen or certain foods. The substances that trigger an allergic reaction are called allergens.
When you are exposed to an allergen, your white blood cells produce antibodies. The antibodies trigger the release of histamine and other chemicals in your blood called mediators. The mediators cause the symptoms of an allergic reaction. The majority of allergic reactions are not life-threatening.
Certain medications, food, and insect stings most frequently cause anaphylaxis, especially penicillin, non-steroid anti-inflammatory drugs (NSAIDS), peanuts, tree nuts, milk, eggs, and shellfish. Insect stings from bees, yellow jackets, wasps, hornets, and fire ants are a common cause of anaphylaxis. The intravenous contrast dye used in radiology imaging, muscle relaxants used in anesthesia, and latex is also common causes of anaphylaxis and anaphylactic shock.
Exercise can cause anaphylaxis. The type of exercise that causes a reaction differs among people. Aerobic exercise; exercising in cold, hot, or humid temperatures; eating before exercising, or just general activity can cause anaphylaxis. In some cases, the cause is unknown (idiopathic anaphylaxis).
Symptoms of anaphylaxis usually develop within seconds or minutes of contact with an allergen; although on rare occasions, delayed symptoms have occurred after 30 minutes. Hives, itching, and pale or flushed (reddened) skin are common skin reactions. It can be difficult to breathe if the airways narrow and the throat and tongue swell. A wheezing noise may be heard while breathing. The pulse may feel weak and fast. Nausea, vomiting, diarrhea, dizziness, and fainting can also occur.
Anaphylaxis is potentially life-threatening. A severe anaphylaxis reaction can cause a person to develop anaphylactic shock and stop breathing or stop the heart. Symptoms of anaphylactic shock include a sudden drop in blood pressure, difficulty breathing, and a loss of consciousness. Again, 911 should be called and emergency medical treatment received if a person is experiencing anaphylaxis. Although it is rare, death can result.
Emergency medical personnel will assess a person’s vital signs. Tell the doctor if the patient was exposed to a known allergen. Inform the doctor if an epinephrine auto-injector was used.
Emergency personnel will deliver medication as necessary to treat an anaphylaxis event. Epinephrine, oxygen, antihistamines, cortisone, and beta-agonists are types of emergency medications that may be delivered. Steroids may be used to treat prolonged symptoms. People with non-life-threatening symptoms are usually released to go home after a period of observation.
Cardiopulmonary resuscitation (CPR), artificial respiratory methods, and other emergencies medical care may be necessary for people with life-threatening symptoms. These people are admitted to the hospital. Following an anaphylaxis event, follow-up evaluation and care by an allergist are recommended.
As a precaution, people who have previously had anaphylaxis and those who are aware of severe allergic reactions to certain allergens will often carry an EpiPen or Twin Injector. These devices deliver a dose of epinephrine to help quickly counteract the symptoms of anaphylaxis. This medication can reverse the allergic reaction, at least temporarily, to provide the life-saving time needed to get further treatment.
If you know you have a serious allergy, wear an emergency alert bracelet or necklace. Carry your auto-injection medication with you at all times. Inform people that are regularly around you what to do if you have an anaphylactic reaction. Follow your allergist’s advice, and attend all of your medical appointments. It is possible for future reactions to be more severe than past reactions, so talk to your doctor about an emergency preparedness plan. Follow your doctor’s advice for preventing allergic reactions.
Am I at Risk
You may have an increased risk of anaphylaxis if:
• You have had an anaphylactic reaction before.
• You have had a severe allergic reaction in the past.
• You have allergies or asthma.
If not treated immediately, death from anaphylaxis can occur. If a severe anaphylactic attack occurs you can stop breathing or your heart can stop. In this case, you’ll need cardiopulmonary resuscitation (CPR) and other emergency treatment right away.
