In most cases, people with allergies develop mild to moderate symptoms, such as watery eyes, a runny nose or a rash. But sometimes, exposure to an allergen can cause a life-threatening allergic reaction known as anaphylaxis. This severe reaction happens when an over-release of chemicals puts the person into shock. Allergies to food, insect stings, medications and latex are most frequently associated with anaphylaxis. Show
A second anaphylactic reaction, known as a biphasic reaction, can occur as long as 12 hours after the initial reaction. Call 911 and get to the nearest emergency facility at the first sign of anaphylaxis, even if you have already administered epinephrine, the drug used to treat severe allergic reactions. Just because an allergic person has never had an anaphylactic reaction in the past to an offending allergen, doesn’t mean that one won’t occur in the future. If you have had an anaphylactic reaction in the past, you are at risk of future reactions.
Don’t let allergies or asthma hold you back. Find an Allergist SymptomsAnaphylaxis symptoms occur suddenly and can progress quickly. The early symptoms may be mild, such as a runny nose, a skin rash or a “strange feeling.” These symptoms can quickly lead to more serious problems, including:
People who have had a severe allergic reaction are at risk for future reactions. Even if your first reaction is mild, future reactions might be more severe. That’s why it’s important to carry self-injectable epinephrine if you are at risk, and 911 should be dialed in the event of a very serious reaction. The best way to understand anaphylaxis and the things that can trigger this severe allergic reaction is to see an allergist who will help you manage your condition. DiagnosisIf you have a history of allergies and/or asthma and have previously had a severe reaction, you are at greater risk for anaphylaxis. Allergists are specially trained to review your history of allergic reactions, conduct diagnostic tests (such as skin-prick tests, blood tests and oral food challenges) to determine your triggers, review treatment options and teach avoidance techniques. Talk with an allergist if:
Management and TreatmentAn anaphylactic reaction should be treated immediately with an injection of epinephrine (adrenaline). Doses, available by prescription, come in an auto-injector that should be kept with you at all times. Two injections may be necessary to control symptoms. Here are some tips for reducing the risk of anaphylaxis:
Be S.A.F.E. Action GuideAllergists and emergency physicians have teamed up to create the Be S.A.F.E. action guide to help you remember steps to take during and after an allergic emergency. S Seek immediate medical help.Call 911 and get to the nearest emergency facility at the first sign of anaphylaxis, even if you have already administered epinephrine, the drug used to treat severe allergic reactions. If you have had an anaphylactic reaction in the past, you are at risk of future reactions. A Identify the Allergen.Think about what you might have eaten or come in contact with – food, insect sting, medication, latex – to trigger an allergic reaction. It is particularly important to identify the cause because the best way to prevent anaphylaxis is to avoid its trigger. F Follow up with a specialist.Ask your doctor for a referral to an allergist/immunologist, a physician who specializes in treating asthma and allergies. It is important that you consult an allergist for testing, diagnosis and ongoing management of your allergic disease. E Carry Epinephrine for emergencies.Kits containing fast-acting, self-administered epinephrine are commonly prescribed for people who are at risk of anaphylaxis. Make sure that you carry an epinephrine kit with you at all times, and that family and friends know of your condition, your triggers and how to use epinephrine. Consider wearing an emergency medical bracelet or necklace identifying yourself as a person at risk of anaphylaxis. Teachers and other caregivers should be informed of children who are at risk for anaphylaxis and know what to do in an allergic emergency. What are the 4 signs someone has gone into anaphylactic shock?Skin reactions, including hives and itching and flushed or pale skin. Low blood pressure (hypotension) Constriction of the airways and a swollen tongue or throat, which can cause wheezing and trouble breathing. A weak and rapid pulse.
What are the 5 symptoms of anaphylaxis?Swelling of the lips, tongue or throat. Shortness of breath, trouble breathing, wheezing (whistling sound during breathing) Dizziness and/or fainting. Stomach pain, vomiting or diarrhea.
Which 3 symptom is a common anaphylactic reaction?The first signs of an anaphylactic reaction may look like typical allergy symptoms: a runny nose or a skin rash. But within about 30 minutes, more serious signs appear. There is usually more than one of these: Coughing; wheezing; and pain, itching, or tightness in your chest.
What are 3 common causes of anaphylactic shock?But sometimes, exposure to an allergen can cause a life-threatening allergic reaction known as anaphylaxis . This severe reaction happens when an over-release of chemicals puts the person into shock. Allergies to food, insect stings, medications and latex are most frequently associated with anaphylaxis.
