What to do for an allergic reaction to allergy shots
An allergen is an otherwise harmless substance that causes an allergic reaction. Allergic rhinitis, or hay fever, is an allergic response to specific allergens. Pollen is the most common allergen in seasonal allergic rhinitis. These are allergy symptoms that happen with the change of seasons.
Nearly 8 percent of adults in the United States experience allergic rhinitis of some helpful, according to the American Academy of Allergy, Asthma & Immunology (AAAAI). Between 10 and 30 percent of the worldwide population may also own allergic rhinitis.
What is the immune system?
The purpose of the immune system is to defend itself and hold microorganisms, such as certain bacteria, viruses, and fungi, out of the body, and to destroy any infectious microorganisms that do invade the body. The immune system is made up of a complicated and vital network of cells and organs that protect the body from infection.
The organs involved with the immune system are called the lymphoid organs.
They affect growth, development, and the release of lymphocytes (a type of white blood cell). The blood vessels and lymphatic vessels are significant parts of the lymphoid organs. They carry the lymphocytes to and from diverse areas in the body. Each lymphoid organ plays a role in the production and activation of lymphocytes.
Lymphoid organs include:
Appendix (a little tube that is connected to the large intestine)
Adenoids (two glands located at the back of the nasal passages)
Spleen (a fist-sized organ located in the abdominal cavity)
Lymph nodes (small organs shaped love beans, which are located throughout the body and join via the lymphatic vessels)
Blood vessels (the arteries, veins, and capillaries through which blood flows)
Lymphatic vessels (a network of channels throughout the body that carries lymphocytes to the lymphoid organs and bloodstream)
Thymus (two lobes that join in front of the trachea behind the breast bone)
Bone marrow (the soft, fatty tissue found in bone cavities)
Peyer’s patches (lymphoid tissue in the little intestine)
Tonsils (two oval masses in the back of the throat)
Anaphylaxis affects at least one in 50 people living in the U.S.
What Is Anaphylaxis?
Anaphylaxis (anna-fih-LACK-sis) is a serious allergic reaction that is rapid in onset and may cause death.
What Are the Symptoms of Anaphylaxis?
Symptoms generally involve more than one organ system (part of the body), such as the skin or mouth, the lungs, the heartand the gut.
Some symptoms include:
- Skin rashes, itching or hives
- Swelling of the lips, tongue or throat
- Uterine cramps
- Dizziness and/or fainting
- Shortness of breath, trouble breathing or wheezing (whistling sound during breathing)
- Stomach pain, bloating, vomiting or diarrhea
- Feeling love something terrible is about to happen
Ask your doctor for a finish list of symptoms and an anaphylaxis action plan. Anaphylaxis must be treated correct away to provide the best chance for improvement and prevent serious, potentially life-threatening complications.
What Can I Do to Prevent Anaphylaxis?
An allergist can assist you create a plan to hold you safe.
- If you own adrug allergy, be familiar with both the generic name and brand names of medicines that cause you to own a severe allergic reaction. And be aware of ingredients in a combination product. Become familiar with medicines that might cause a cross-reaction. Read drug information carefully.
- If you own a food allergy, be careful about everything you eat. Check ingredients on every food labels.
Wash hands, and use clean surfaces and utensils to prepare food. Enquire restaurant staff how they prepare foods. (Learn more on our related website for Kids With Food Allergies:What Is a Food Allergy?)
- If you react to insect stings or exercise, talk to your doctor about how to avoid these reactions.
- Carry your epinephrine auto-injectors with you at every times.This is extremely significant and can save your life or the life of a loved one.
- Prepare with a plan.Have your doctor assist you create an anaphylaxis action plan.
- Talk to your doctor and caregivers.Make certain they know the names of any medications you are allergic to and what symptoms you had when you took them.
Give them a list of every drug you take. Some common medicines, love beta-blockers, can worsen anaphylaxis.
- Wear a medical ID bracelet or necklace.It lets others know of your allergy in an emergency. Also, hold a card in your wallet or purse that explains your allergy.
What Causes Anaphylaxis?
An allergy occurs when the body’s immune system sees something as harmful and reacts. Your immune system tries to remove or isolate the trigger. The result is symptoms such as vomiting or swelling. The most common triggers of anaphylaxis areallergens.
Medicines, foods, insect stings and bites, and latex most often cause severe allergic reactions.
- Medicines are the leading cause in adults
Common culprits are penicillin and other antibiotics, aspirin and aspirin-related products and insulin.
- Foods are the leading cause in children
In the U.S., the most common food allergies are peanuts, tree nuts, shellfish, fish, milk, eggs, soy and wheat. These are the “top 8 allergens.” In children, the most common food allergies are milk, eggs, peanuts, soy and wheat.
In adults, the most common food allergies are shellfish, tree nuts and peanuts.
Natural rubber latex may cause a mild skin irritation or it can trigger a severe allergic reaction. Direct contact with latex items (latex gloves, condoms and balloons) can cause a reaction. Inhaling little latex particles that own become airborne can trigger latex allergy.
Putting on and removing latex gloves can release little latex particles into the air.
- Insect stings and bites
Stinging insects such as bees, wasps, hornets, yellow jackets and fire ants can cause anaphylaxis. Certain tick bites can cause a person to develop severe allergic reactions to meat. Bites from the "kissing bug" and deer fly also cause a local allergic reaction.
- Physical activity
Exercise-induced anaphylaxis is a rare allergic reaction that occurs after vigorous physical activity. Temperature, seasonal changes, drugs, alcohol or eating certain foods before exercise may be co-factors.
In other words, both exercise and this other factor own to be present for a person to own the severe allergic reaction.
With proper evaluation, allergists identify most causes of anaphylaxis. Some people own allergic reactions without any known exposure to common allergens. If an allergist cannot identify a trigger, the condition isidiopathic anaphylaxis.
What Is the Treatment for Anaphylaxis?
Epinephrine (ep-uh-NEF-rin) is the most significant treatment available. Always carry two epinephrine auto-injectors so you can quickly treat a reaction wherever you are. (Learn more on our related website for Kids With Food Allergies:Epinephrine Is the First Line of Treatment for Severe Allergic Reactions).
- Promptly inject the medicine at the first sign of an anaphylactic reaction.Consider carrying your anaphylaxis action plan along with your auto-injectors.
- Call to go to a hospital by ambulance.
You must seek medical careimmediately– even if you feel better – because symptoms can recur.
- You may need other treatments, in addition to epinephrine.
How Can I Tell the Difference Between Anaphylaxis and Asthma?
People with asthma often own allergies as well. This puts them at higher risk of developing anaphylaxis, which also can cause breathing problems. For that reason, it is significant to manage your asthma well.
Some of the symptoms of a severe allergic reaction or a severe asthma attack may seem similar. A helpful clue to tell the these apart is that anaphylaxis may closely follow ingestion of a medication, eating a specific food, or getting stung or bitten by an insect.
If you are unsure if it is anaphylaxis or asthma:
- Use your epinephrine auto-injector first (it treats both anaphylaxis and asthma).
- Then use your asthma relief inhaler (e.g.
- Call and go to the hospital by ambulance.
Who Is At Risk for Anaphylaxis?
- People who own experienced anaphylaxis before
- People with allergies to foods, insect stings, medicine and other triggers
If you are at-risk:
- Keep your epinephrine auto-injectors on-hand at every times and be ready to use them if an emergency occurs.
- Talk with your doctor about your triggers and your symptoms. Your doctor may tell you to see an allergist. An allergist can assist you identify your allergies and study to manage your risk of severe reactions.
- Ask your doctor for an anaphylaxis action plan.
This will assist you know what to do if you experience anaphylaxis.

If you ponder you are having anaphylaxis, use your self-injectable epinephrine and call
Do not delay. Do not take antihistamines in put of epinephrine. Epinephrine is the most effective treatment for anaphylaxis.
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.
A second anaphylactic reaction, known as a biphasic reaction, can happen as endless as 12 hours after the initial reaction.
Call and get to the nearest emergency facility at the first sign of anaphylaxis, even if you own already istered 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 happen in the future.
If you own had an anaphylactic reaction in the past, you are at risk of future reactions.
Allergic disease is one of the most common chronic health conditions in the world. People with a family history of allergies own an increase risk of developing allergic disease. Hay fever (allergic rhinitis), eczema, hives, asthma, and food allergy are some types of allergic diseases. Allergy symptoms can range from mild to a serious, life-threatening allergic reaction (anaphylaxis).
Allergic reactions start in your immune system. When a harmless substance such as dust, mold, or pollen is encountered by a person who is allergic to that substance, the immune system may over react by producing antibodies that «attack» the allergen.
The can cause wheezing, itching, runny nose, watery or itchy eyes, and other symptoms.
What is anaphylactic shock?
Anaphylactic shock, also called anaphylaxis, is a severe, life-threatening reaction to certain allergens. Body tissues may swell, including tissues in the throat. Anaphylactic shock is also characterized by a sudden drop in blood pressure. The following are the most common symptoms of anaphylactic shock. However, each person may experience symptoms differently. Other symptoms may include:
Swelling of the throat and tongue or tightness in throat
Loss of consciousness
Itching and hives over most of the body
Nausea, vomiting, or diarrhea
Difficulty breathing or shortness of breath
Pain or cramps
Abnormal heart rate (too quick or too slow)
Anaphylactic shock can be caused by an allergic reaction to a drug, food, serum, insect venom, allergen extract, or chemical.
Some people who are aware of their allergic reactions or allergens carry an emergency anaphylaxis kit that contains injectable epinephrine (a drug that stimulates the adrenal glands and increases the rate and force of the heartbeat).

Symptoms of allergic rhinitis
Common symptoms of allergic rhinitis include:
You’ll generally feel one or more of these symptoms immediately after coming into contact with an allergen. Some symptoms, such as recurrent headaches and fatigue, may only happen after long-term exposure to allergens.
Fever isn’t a symptom of hay fever.
Some people experience symptoms only rarely. This likely occurs when you’re exposed to allergens in large quantities. Other people experience symptoms every year endless. Talk to your doctor about possible allergies if your symptoms final for more than a few weeks and don’t seem to be improving.
How does a person become allergic?
Allergens can be inhaled, ingested, or enter through the skin. Common allergic reactions, such as hay fever, certain types of asthma, and hives are linked to an antibody produced by the body called immunoglobulin E (IgE).
Each IgE antibody can be extremely specific, reacting against certain pollens and other allergens. In other words, a person can be allergic to one type of pollen, but not another. When a susceptible person is exposed to an allergen, the body starts producing a large quantity of similar IgE antibodies. The next exposure to the same allergen may result in an allergic reaction. Symptoms of an allergic reaction will vary depending on the type and quantity of allergen encountered and the manner in which the body’s immune system reacts to that allergen.
Allergies can affect anyone, regardless of age, gender, race, or socioeconomic status.
Generally, allergies are more common in children. However, a first-time occurrence can happen at any age, or recur after numerous years of remission. Hormones, stress, smoke, perfume, or environmental irritants may also frolic a role in the development or severity of allergies.
