Anaphylaxis is a severe, potentially life-threatening allergic reaction that can occur within seconds or minutes of exposure to an allergen. It is a medical emergency that requires immediate treatment.
Anaphylaxis is caused by the body's immune system overreacting to an allergen, such as peanuts, shellfish, insect stings, or certain medications. When the allergen enters the body, the immune system releases a flood of chemicals, including histamine, which cause the symptoms of anaphylaxis.
The symptoms of anaphylaxis can vary from person to person, but they often include difficulty breathing, swelling of the face, throat, and tongue, hives, nausea, vomiting, and dizziness. In severe cases, anaphylaxis can lead to loss of consciousness and death.

Sudden onset
One of the most important things to know about anaphylaxis is that it can come on very suddenly. Symptoms can develop within seconds or minutes of exposure to an allergen.
- Rapid progression:
Anaphylaxis can progress very quickly. Symptoms can worsen rapidly, and it is important to seek medical attention immediately.
- Life-threatening:
Anaphylaxis can be life-threatening if it is not treated promptly. In severe cases, it can lead to loss of consciousness and death.
- Unpredictable:
It is difficult to predict who will experience anaphylaxis and when it will occur. Even people who have had mild allergic reactions in the past may experience anaphylaxis the next time they are exposed to the same allergen.
- Be prepared:
If you have a known allergy that could cause anaphylaxis, it is important to be prepared. Carry an epinephrine auto-injector (EpiPen) with you at all times, and make sure you know how to use it.
The sudden onset of anaphylaxis is one of the things that makes it so dangerous. It is important to be aware of the signs and symptoms of anaphylaxis and to seek medical attention immediately if you think you or someone else is experiencing it.
Can be fatal
Anaphylaxis is a medical emergency that can be fatal if it is not treated promptly. In severe cases, anaphylaxis can lead to loss of consciousness and death.
- Airway obstruction:
Anaphylaxis can cause swelling of the throat and airways, which can make it difficult to breathe. In severe cases, this can lead to respiratory arrest.
- Cardiovascular collapse:
Anaphylaxis can also cause a sudden drop in blood pressure, which can lead to cardiovascular collapse. This can be fatal if it is not treated immediately.
- Shock:
Anaphylaxis can also lead to shock, which is a life-threatening condition that occurs when the body is unable to get enough oxygen and nutrients to its cells.
- Multiple organ failure:
In severe cases, anaphylaxis can lead to multiple organ failure, which can be fatal.
The severity of anaphylaxis can vary from person to person. Some people may experience only mild symptoms, while others may experience severe, life-threatening symptoms. It is important to be aware of the signs and symptoms of anaphylaxis and to seek medical attention immediately if you think you or someone else is experiencing it.
Triggered by allergens
Anaphylaxis is triggered by allergens, which are substances that the body perceives as harmful. Common allergens include:
- Foods:
Peanuts, tree nuts, shellfish, milk, eggs, soy, and wheat are some of the most common food allergens.
- Insect stings:
Insect stings, particularly from bees, wasps, and yellow jackets, can cause anaphylaxis in some people.
- Medications:
Certain medications, such as penicillin and other antibiotics, aspirin, and ibuprofen, can cause anaphylaxis in some people.
- Latex:
Some people are allergic to latex, which is a natural rubber found in many products, such as gloves, balloons, and condoms.
It is important to know what allergens you are allergic to so that you can avoid them. If you have a known allergy, it is important to carry an epinephrine auto-injector (EpiPen) with you at all times and to make sure you know how to use it.
Symptoms include difficulty breathing and swelling
Anaphylaxis can cause a variety of symptoms, including difficulty breathing and swelling. These symptoms can be life-threatening if they are not treated promptly.
- Difficulty breathing:
Anaphylaxis can cause swelling of the throat and airways, which can make it difficult to breathe. This can be a life-threatening symptom.
- Swelling:
Anaphylaxis can also cause swelling of the face, lips, tongue, and extremities. This swelling can be itchy and uncomfortable, and it can also be a sign of a more serious allergic reaction.
- Hives:
Hives are a common symptom of anaphylaxis. They are raised, itchy welts that can appear anywhere on the body.
- Nausea and vomiting:
Anaphylaxis can also cause nausea and vomiting. These symptoms can be severe and can lead to dehydration.
If you experience any of these symptoms, especially if they occur suddenly after exposure to an allergen, it is important to seek medical attention immediately. Anaphylaxis is a medical emergency that can be fatal if it is not treated promptly.
Requires immediate treatment
Anaphylaxis is a medical emergency that requires immediate treatment. If you think someone is experiencing anaphylaxis, call 911 immediately.
- Epinephrine:
The first-line treatment for anaphylaxis is epinephrine. Epinephrine is a medication that helps to open up the airways, reduce swelling, and improve blood pressure. Epinephrine is available in an auto-injector, which is a small device that delivers a single dose of epinephrine. People who are at risk for anaphylaxis should carry an epinephrine auto-injector with them at all times.
- Antihistamines:
Antihistamines are medications that can help to relieve the symptoms of anaphylaxis, such as hives and itching. Antihistamines are not a substitute for epinephrine, but they can be used in addition to epinephrine to help relieve symptoms.
- Corticosteroids:
Corticosteroids are medications that can help to reduce inflammation. Corticosteroids may be given to people who are experiencing anaphylaxis to help prevent a relapse.
- Oxygen:
Oxygen may be given to people who are experiencing anaphylaxis to help improve their breathing.
The goal of treatment for anaphylaxis is to stop the allergic reaction and prevent serious complications. Treatment should be started as soon as possible after the onset of symptoms.
Can be managed with epinephrine
Epinephrine, commonly known as epinephrine, is a hormone that is produced naturally by the body in response to stress. It helps to open up the airway, constrict blood vessels, and increase heart rate. Epinephrine can be used to treat anaphylactic shock, a severe allergic reaction that can be fatal if not treated immediately.
Epinephrine is available in an auto-injector, which is a small device that delivers a single dose of epinephrine. People who are at risk for anaphylactic shock should carry an epinephrine auto-injector with them at all times.
To use an epinephrine auto-injector, follow these steps:
- Remove the cap: Grasp the auto-injector with one hand and use your other hand to remove the cap.
- Place the auto-injector on your thigh: Position the auto-injector against the outer thigh, with the orange tip pointing towards your leg. Make sure that the auto-injector is not pointing at your hand or any other body part.
- Press the auto-injector: Use your fist to press the auto-injector firmly against your thigh. You will hear a click when the epinephrine is injected.
- Hold the auto-injector in place for 10 seconds: Keep the auto-injector pressed against your thigh for 10 seconds, even after you hear the click. This will ensure that the epinephrine is fully injected.
- Call 911: After using the epinephrine auto-injector, call 911 immediately. Even if you feel better, it is important to be seen by a doctor as soon as possible.
Epinephrine auto-injectors are available by prescription. If you have a known allergy that could cause anaphylactic shock, talk to your doctor about getting an epinephrine auto-injector.
Epinephrine is a life-saving medication that can be used to treat anaphylactic shock. If you have a known allergy that could cause anaphylactic shock, it is important to carry an epinephrine auto-injector with you at all times.
Prevention is key
The best way to prevent anaphylaxis is to avoid exposure to the allergens that trigger it. This can be difficult, especially if you have a food allergy or an allergy to insect stings. However, there are a number of things you can do to reduce your risk of anaphylaxis, including:
