There may also be other allergy symptoms , including an itchy, raised rash hives ; feeling or being sick; swelling angioedema or stomach pain. Anaphylaxis is a medical emergency. It can be very serious if not treated quickly. If you're having an anaphylactic reaction, you can follow these steps yourself if you feel able to. You may also receive glucocorticoid and antihistamines intravenously. These medications help to reduce inflammation in the air passages, improving your ability to breathe.
Your doctor may give you beta-agonists such as albuterol to make breathing easier. You may also receive supplemental oxygen to help your body get the oxygen it needs. Anaphylactic shock can be extremely dangerous, even fatal.
Recovery will depend on how quickly you get help. Long term, you may be prescribed antihistamines or other allergy medication to reduce the likelihood or severity of future attacks. You should always take the allergy medications prescribed to you by your doctor and consult them before stopping.
Your doctor may suggest carrying an EpiPen in case of a future attack. They may also help you identify what caused the reaction so you can avoid triggers in the future. From first exposure to life-threatening complications, learn how quickly an allergy attack can escalate and why it can become life threatening. Anaphylaxis is a life-threatening allergic reaction that causes a range of symptoms. Check out pictures of the symptoms, and learn more about them. Bee sting allergy refers to a serious bodily reaction to bee venom.
Learn about symptoms and treatment. Getting a shot of emergency epinephrine as quickly as possible can save your life — but what should you do afterward? If you have an allergy to peanuts, you may be at risk for delayed anaphylaxis. Treatment always begins with the administration of epinephrine. In cases of severe anaphylactic shock, a person may need additional treatment. This may include the following therapies and medications:. It is important for people with a history of anaphylactic reactions to know which substances or allergens trigger symptoms.
A doctor will typically recommend allergy testing. This is because people with a history of anaphylactic reactions to one substance may also have severe allergic reactions to other allergens. Avoiding these allergens can be lifesaving. People who are allergic to substances that cannot be avoided, such as insect stings, may be able to prevent anaphylaxis with allergy treatment.
Desensitization , also known as immunotherapy or allergy shots, involves slow and steady exposure to tiny amounts of an allergen to reduce the risk of an allergic reaction. People can ask for a referral to an allergist who can decide whether desensitization is an option. People have anaphylactic reactions because of allergies. The body produces proteins that can attack dangerous invaders, including viruses and bacteria. A person with allergies produces immunoglobulin E IgE proteins in response to harmless substances.
These substances trigger white blood cells called mast cells to release specific chemicals, often histamines that cause an allergic reaction. After a first anaphylactic reaction, it is essential to follow up with a doctor. This may include getting a prescription for an EpiPen and assessing the risk of future reactions. People who already know they have an allergy should also follow up with a doctor after every anaphylactic reaction.
They should discuss with a doctor planning in case of a future emergency. People with an EpiPen should inject epinephrine, as soon as possible, before going to the emergency room. Anaphylaxis and anaphylactic shock can cause fatal respiratory complications.
If anaphylaxis isn't treated right away, it can be fatal. Anaphylaxis symptoms usually occur within minutes of exposure to an allergen. Sometimes, however, anaphylaxis can occur a half-hour or longer after exposure. In rare cases, anaphylaxis may be delayed for hours.
Signs and symptoms include:. Seek emergency medical help if you, your child or someone else you're with has a severe allergic reaction. Don't wait to see if the symptoms go away.
If you have an attack and you carry an epinephrine autoinjector, administer it right away. Even if symptoms improve after the injection, you still need to go to an emergency room to make sure symptoms don't recur, even without more exposure to the allergen. This second reaction is called biphasic anaphylaxis. Make an appointment to see your provider if you or your child has had a severe allergy attack or signs and symptoms of anaphylaxis in the past.
The diagnosis and long-term management of anaphylaxis are complicated, so you'll probably need to see a doctor who specializes in allergies and immunology.
The immune system produces antibodies that defend against foreign substances. This is good when a foreign substance is harmful, such as certain bacteria or viruses. But some people's immune systems overreact to substances that don't normally cause an allergic reaction.
