What are the common symptoms of pet allergies. How can you effectively manage and treat allergies to dogs and cats. What steps can be taken to reduce exposure to pet allergens in the home.

Understanding Pet Allergies: Causes and Triggers

Pet allergies are a common issue affecting many individuals worldwide. These allergies occur when the immune system overreacts to proteins found in an animal’s dander, saliva, or urine. While any animal with fur can potentially trigger an allergic reaction, cats and dogs are the most common culprits in household settings.

The primary allergens produced by cats are proteins found in their saliva, skin cells (dander), and urine. These proteins are particularly small and lightweight, allowing them to remain airborne for extended periods. As noted by Allergist Dana Wallace, MD, “Of all the pollen, mold, animal dander, and dust mites that we have studied, cat dander is absolutely the smallest. This means that the allergen remains airborne for at least 30 minutes after you disturb it in a room, allowing for constant exposure to allergic patients.”

Dogs also produce allergens, primarily found in their dander and saliva. Unlike popular belief, there is no truly hypoallergenic breed of cat or dog. While some breeds may produce fewer allergens, all pets produce some level of allergenic proteins.

Recognizing Pet Allergy Symptoms

Pet allergy symptoms can range from mild to severe, depending on an individual’s sensitivity and the level of exposure to allergens. Common symptoms include:

• Sneezing
• Runny or stuffy nose
• Facial pain (from nasal congestion)
• Coughing, chest tightness, shortness of breath, and wheezing
• Watery, red, or itchy eyes
• Skin rash or hives

These symptoms may develop quickly upon exposure to pet allergens or may take time to manifest. In some cases, symptoms may persist even after the pet is no longer present, as allergens can linger in the environment.

Can pet allergy symptoms vary in severity?

Yes, pet allergy symptoms can indeed vary in severity. Some individuals may experience mild discomfort, such as occasional sneezing or itchy eyes, while others may develop more severe reactions, including difficulty breathing or asthma attacks. The severity of symptoms often depends on factors such as the individual’s sensitivity to the allergen, the concentration of allergens in the environment, and the duration of exposure.

Diagnosing Pet Allergies: When to See an Allergist

If you suspect you have a pet allergy, it’s crucial to consult with an allergist for proper diagnosis and treatment. An allergist can perform various tests to confirm the presence of pet allergies and determine the specific allergens causing your symptoms.

Common diagnostic methods include:

1. Skin prick tests: Small amounts of potential allergens are placed on the skin to observe any reactions.
2. Blood tests: These measure the presence of specific antibodies related to pet allergies.
3. Intradermal tests: Similar to skin prick tests but involve injecting allergens under the skin.

Early diagnosis is essential for effective management of pet allergies and prevention of more severe symptoms or complications.

How accurate are pet allergy tests?

Pet allergy tests are generally quite accurate, with skin prick tests having a sensitivity of around 80-90%. However, it’s important to note that no test is 100% accurate, and false positives or negatives can occur. That’s why allergists often combine test results with a patient’s medical history and symptoms to make a definitive diagnosis.

Effective Management Strategies for Pet Allergies

Managing pet allergies involves a combination of avoidance strategies, environmental controls, and medical treatments. Here are some effective ways to manage pet allergies:

1. Avoidance: The most effective way to prevent pet allergy symptoms is to avoid exposure to the allergen. This may involve rehoming pets or limiting contact with animals.
2. Environmental controls: If complete avoidance is not possible, implementing strict environmental controls can help reduce allergen exposure. This includes:
   • Keeping pets out of bedrooms and other areas where you spend a lot of time
   • Using high-efficiency particulate air (HEPA) filters in your home
   • Regularly cleaning and vacuuming with a HEPA-filter vacuum cleaner
   • Washing pets weekly to reduce allergen levels
3. Medications: Various over-the-counter and prescription medications can help manage pet allergy symptoms:
   • Antihistamines to reduce sneezing, runny nose, and itchy eyes
   • Nasal corticosteroids to reduce inflammation and congestion
   • Decongestants to relieve nasal congestion
   • Bronchodilators for asthma-like symptoms
4. Immunotherapy: For severe or persistent allergies, allergen immunotherapy (allergy shots) may be recommended. This treatment involves gradually exposing the body to increasing amounts of the allergen to build tolerance over time.

Is it possible to develop tolerance to pet allergens over time?

While some people may report developing a tolerance to pet allergens over time, this is not a reliable or predictable occurrence. In fact, prolonged exposure to allergens can sometimes lead to worsening symptoms or the development of additional allergies. It’s always best to work with an allergist to develop a safe and effective management plan rather than relying on the possibility of naturally outgrowing the allergy.

The Impact of Pet Allergies on Daily Life

Pet allergies can significantly impact an individual’s quality of life, affecting various aspects of daily living. Some of the ways pet allergies can influence daily life include:

• Limitations on social interactions: Visiting friends or family members with pets may become challenging
• Workplace difficulties: Pet allergens can be brought into work environments on clothing, potentially causing symptoms
• Travel restrictions: Staying in hotels or vacation rentals that allow pets may trigger allergic reactions
• Emotional stress: The need to rehome a beloved pet due to allergies can be emotionally taxing
• Sleep disturbances: Nighttime allergy symptoms can lead to poor sleep quality and daytime fatigue

Understanding these potential impacts can help individuals with pet allergies make informed decisions about their lifestyle and treatment options.

How can pet allergies affect children in school settings?

Pet allergies can pose unique challenges for children in school settings. Allergens can be brought into classrooms on the clothing of students and teachers who have pets at home. This indirect exposure can lead to persistent symptoms, affecting a child’s ability to concentrate and participate fully in school activities. Additionally, class pets or therapy animals used in schools may trigger allergic reactions in sensitive children. It’s important for parents to work closely with school administrators and teachers to ensure appropriate accommodations are made for children with pet allergies.

Emerging Treatments and Research in Pet Allergy Management

The field of allergy treatment is continually evolving, with researchers exploring new approaches to managing pet allergies. Some promising areas of research include:

1. Novel immunotherapy approaches: Researchers are investigating new methods of delivering immunotherapy, such as sublingual immunotherapy (under the tongue) and epicutaneous immunotherapy (through the skin), which may offer more convenient alternatives to traditional allergy shots.
2. Biologics: These are targeted therapies that block specific components of the allergic response. While currently used primarily for severe asthma and other allergic conditions, research is ongoing to evaluate their potential in treating pet allergies.
3. Gene therapy: Scientists are exploring the possibility of modifying genes involved in allergic responses to potentially prevent or cure allergies at a genetic level.
4. Hypoallergenic pets: While no truly hypoallergenic cats or dogs exist, research continues into breeding practices and genetic modifications that could result in pets producing fewer allergens.

These emerging treatments offer hope for more effective management of pet allergies in the future, potentially improving the quality of life for those affected by these conditions.

What role does genetic research play in understanding pet allergies?

Genetic research plays a crucial role in understanding pet allergies. Scientists have identified several genes associated with an increased risk of developing allergies, including those specific to pet allergies. This research not only helps explain why some individuals are more prone to allergies than others but also paves the way for potential genetic therapies. By understanding the genetic basis of allergies, researchers hope to develop more targeted and personalized treatments in the future, potentially even preventing the development of allergies in susceptible individuals.

Living with Pets Despite Allergies: Is It Possible?

For many people with pet allergies, the thought of giving up a beloved pet is heartbreaking. While it’s generally recommended to avoid allergens, some individuals may choose to keep their pets despite allergies. If you decide to live with a pet despite having allergies, here are some strategies that may help minimize symptoms:

• Create pet-free zones: Designate certain areas of your home, especially bedrooms, as pet-free zones to reduce allergen exposure during sleep.
• Use air purifiers: High-quality air purifiers with HEPA filters can help remove allergens from the air.
• Groom pets regularly: Frequent brushing and bathing of pets can help reduce the amount of allergens they shed. It’s best if a non-allergic person performs these tasks.
• Clean frequently: Regular vacuuming with a HEPA filter vacuum, dusting, and washing of pet bedding can help reduce allergen levels in the home.
• Consider medication: Work with your allergist to develop a medication regimen that can help control your symptoms.
• Explore immunotherapy: Allergy shots may help increase your tolerance to pet allergens over time.

It’s important to note that these measures may not be sufficient for everyone, especially those with severe allergies or asthma. Always consult with your allergist before deciding to keep a pet despite allergies.

Can air purifiers effectively remove pet allergens from indoor air?

Yes, air purifiers can be effective in removing pet allergens from indoor air, but their efficiency depends on several factors. High-quality air purifiers equipped with HEPA (High-Efficiency Particulate Air) filters are capable of capturing particles as small as 0.3 microns, which includes most pet allergens. However, the effectiveness of an air purifier also depends on the size of the room, the air exchange rate, and the overall cleanliness of the environment. While air purifiers can significantly reduce airborne allergens, they should be used in conjunction with other allergen reduction strategies for best results. It’s also important to regularly maintain and replace filters as recommended by the manufacturer to ensure optimal performance.

Pets, Dog and Cat Allergies | Symptoms & Treatment

Overview

A pet </span>” rel=”tooltip”>allergy can contribute to constant allergy symptoms, as exposure can occur at work, school, day care or in other indoor environments, even if a pet is not present.

Pet Allergy Symptoms

• Sneezing
• Runny or stuffy nose
• Facial pain (from nasal congestion)
• Coughing, chest tightness, shortness of breath and wheezing
• Watery, red or itchy eyes
• Skin rash or hives

Pet Allergy Management and Treatment

• Avoid being around dogs and cats; if you have a pet at home, take specific steps to limit exposure.
• Nasal sprays, antihistamines and bronchodilators can help relieve symptoms.
• Consider allergy shots ( Immunotherapy involves giving gradually increasing doses of the substance, or allergen, to which the person is allergic.

It’s time for an allergist.

Cat Allergies

If your nose runs and your eyes water or you start sneezing and wheezing after petting or playing with a cat, you likely have a cat allergy. A cat allergy can contribute to constant allergy symptoms, as exposure can occur at work, school, day care or in other indoor environments, even if a cat is not present.

Cats produce multiple allergens (proteins that can cause allergy). These allergens are found on the fur and skin and in saliva. All cats produce allergens; studies have not shown that cats can be hypoallergenic (meaning that they don’t cause allergy). Homes with more than one cat have higher levels of cat allergens. Characteristics such as the length of a cat’s hair, its sex and the amount of time a cat spends indoors are not associated with cat allergen levels.

Dust and pollen in a cat’s coat can also cause allergy symptoms. In those cases, the allergy is to the dust or pollen, not to the cat.

Of all the pollen, and mold, and animal dander, dust mites that we have studied, the cat dander is absolutely the smallest dander. And what that means is that allergen remains airborne for at least 30 minutes after you disturb it in the room. That just allows the allergic patient to have a constant exposure to that allergen.

Allergist Dana Wallace, MD

Cat Allergy Symptoms

Cat allergy symptoms range from mild to severe, depending on an individual’s sensitivity and the level of exposure to allergens. Those variables may also influence how quickly symptoms develop after exposure. Highly sensitive people can develop symptoms, including breathing problems or a rash, within minutes of touching a cat or entering a house with a cat.

Cat allergy symptoms may include:

• Sneezing or a runny or stuffy nose
• Facial pain (from nasal congestion)
• Coughing, chest tightness, shortness of breath and wheezing
• Watery, red or itchy eyes
• Skin rash or hives

Some people may also develop a rash or hives after being scratched by a cat.

Diagnosing Cat Allergies

Do you suspect you’re suffering from cat allergies? An allergist can provide you with a diagnosis and treatment.

A skin-prick test is the most common way of diagnosing a cat allergy. For this test, a small amount of an extract of cat allergen is placed on your skin. Your skin is then pricked with a small, sterile probe, allowing the liquid to seep under the skin’s surface. You’ll then be monitored for swelling and redness or other signs of a reaction, signaling an allergy. Results typically become evident within 15 to 20 minutes.

Even if you’re sure your symptoms are caused by a cat, it’s a good idea to be tested, since the symptoms may actually be caused by other environmental exposures.

Cat Allergy Management and Treatment

Avoidance is the best way to manage a cat allergy. If you have a cat and are allergic to cats, consider removing the cat from the home.

If you have a cat but don’t want to find it a new home, or if your family wants a cat even though someone in the household is allergic, here are some strategies that may help keep symptoms at bay:

• Keep the cat out of your bedroom and restrict it to only a few rooms. Be advised that keeping the cat in only one room will not limit the allergens to that room.
• Don’t pet, hug or kiss the cat; if you do, wash your hands with soap and water.
• High-efficiency particulate air (HEPA) cleaners run continuously in a bedroom or living room can reduce allergen levels over time.
• Regular use of a high-efficiency vacuum cleaner or a central vacuum can reduce allergen levels.
• Giving your cat a bath at least once a week can reduce airborne cat allergen.

Treatments for cat allergy vary, depending on the symptoms.

Your allergist can help determine what treatment would be best to treat your cat allergy. Nasal symptoms often are treated with steroid nasal sprays, oral antihistamines or other oral medications. Eye symptoms are often treated with antihistamine eyedrops.

Dog Allergy

If your nose runs or you start sneezing and wheezing after petting or playing with a dog, you may be allergic to dogs.

Dogs produce multiple allergens, or proteins that can cause allergy. These allergens are found in dog hair, dander, saliva and urine. All dogs produce allergens; studies have not shown that dogs can be hypoallergenic (not cause allergy). Dog allergen levels increase if the dog lives indoors and are higher in the rooms where a dog is allowed.

Dust and pollen in a dog’s coat can also cause allergy symptoms. In those cases, the allergy is to dust or pollen, not to the dog.

If you remove a cat from a home, you clean all the walls down, do the laundry, do the draperies, it still takes six months for the level of cat protein to get down to normal.

Dog Allergy Symptoms

Do you suspect you’re suffering from dog allergies? An allergist can provide proper diagnosis and treatment.

Symptoms may include:

• Sneezing or a runny or stuffy nose
• Facial pain (from nasal congestion)
• Coughing, chest tightness, shortness of breath, and wheezing
• Watery, red or itchy eyes
• Skin rash or hives

Some people may also develop a rash or hives after being scratched or licked by a dog.

Is there an allergy-free dog?

While poodles, Portuguese water dogs and a number of other breeds (including several types of terriers) have a reputation for being hypoallergenic, a truly allergy-free breed does not exist. A 2011 study compared dust samples from homes with dog breeds reported to be hypoallergenic and those of homes with other dogs. The levels of dog allergen in homes with “hypoallergenic” dogs did not differ from the levels in homes with other breeds.

Insect Sting Allergies | Symptoms & Treatment

Diagnosing

If you are concerned that you may have an "}" data-sheets-userformat="{"2":8963,"3":{"1":0},"4":[null,2,16777215],"11":4,"12":0,"16":10}">Allergies are inappropriate or exaggerated reactions of the immune system to substances that, in the majority of people, cause no symptoms. Symptoms of the allergic diseases may be caused by exposure of the skin to a chemical, of the respiratory system to particles of dust or pollen (or other substances), or of the stomach and intestines to a particular food.</span>” rel=”tooltip”>allergy to insect venom, your best option is to see an allergist.

Your allergist should take a detailed medical history, including questions about previous stings (how many there have been and where you were stung), your reaction to those stings (what you experienced, how long the reaction lasted and what you did to get relief) and any additional symptoms.

Your allergist may perform one or more tests to diagnose allergy to insect venom, such as a skin-prick test, an intradermal skin test or a blood test.

In the skin-prick test, a small amount of a liquid containing insect venom is placed on the back or forearm, which is then pricked with a small, sterile probe to allow the liquid to seep into the skin. If a raised, reddish spot forms within 15 to 20 minutes, that can indicate an allergy. In the blood test, a blood sample is sent to a laboratory to test for the presence of immunoglobulin E (IgE) antibodies to insect venom.

If the skin prick test is negative or inconclusive your allergist will likely recommend an intradermal skin test, in which a small amount of venom extract is injected just under the skin. The site is examined after about 15 minutes for signs of an allergic reaction. This test is considered more accurate than the skin-prick or blood tests in determining the presence of IgE antibodies. If both skin prick and intradermal skin tests are negative then your allergist may recommend a blood test.

The strength of a reaction to a skin or blood test does not indicate how severe your allergic reaction will be the next time you are stung.

Management and Treatment

Insect sting allergy is treated in a two-step approach:

1. The first step is the emergency treatment of the symptoms of a serious reaction when they occur.
2. The second step is preventive treatment of the underlying allergy with venom immunotherapy.

Life-threatening allergic reactions can progress very rapidly and require immediate medical attention. Emergency treatment usually includes administration of certain drugs, such as epinephrine, antihistamines, and in some cases, corticosteroids, intravenous fluids, oxygen and other treatments. Once stabilized, these patients sometimes require close observation in the hospital overnight.

Injectable epinephrine for self-administration is often prescribed as emergency rescue medication for treating an allergic reaction. People who have had previous allergic reactions and rely on epinephrine must remember to carry it with them at all times. Also, because one dose may not be enough to reverse the reaction, recent guidelines recommend keeping two doses of injectable epinephrine available and to activate emergency medical services if used. Even if symptoms improve after a single dose of epinephrine, immediate medical attention following an insect sting is recommended.

Venom Immunotherapy

The long-term treatment of insect sting allergy is called venom immunotherapy, a highly effective program administered by an allergist, which can prevent future allergic reactions to insect stings.

Venom immunotherapy involves administering gradually increasing doses of venom to decrease a patient’s sensitivity to the venom. This can reduce the risk of a future allergic reaction to that of the general population. In a matter of weeks to months, people who previously lived under the constant threat of severe reactions to insect stings can return to leading normal lives.

If you think you might be allergic to insect stings, talk to your allergist. Based on your past history and certain tests, the allergist will determine if you are a candidate for skin testing and immunotherapy.

Avoiding Insect Stings

Knowing how to avoid stings from fire ants, honeybees, wasps, hornets and yellow jackets leads to a more enjoyable summer for everyone. Stinging insects are most active during the late spring, summer, summer and early fall. Insect repellents do not work against stinging insects.

Yellow jackets will nest in the ground and in walls. Hornets and wasps will nest in bushes, trees and on buildings. Use extreme caution when working or playing in these areas. Avoid open garbage cans and exposed food at picnics, which attract yellow jackets. Also, try to reduce the amount of exposed skin when outdoors.

Effective methods for insecticide treatment of fire ant mounds use attractant baits. These baits often contain soybean oil and corn grits combined with chemical agents. The bait is picked up by the worker ants and taken deeper into the mound to the queen. It can take weeks for these insecticides to work.

Allergists recommend the following additional precautions to avoid insect stings:

• Avoid wearing sandals or walking barefoot in the grass. Honeybees and bumblebees forage on white clover, a weed that grows in lawns throughout the country.
• Never swat at a flying insect. If need be, gently brush it aside or patiently wait for it to leave.
• Do not drink from open beverage cans. Stinging insects will crawl inside a can attracted by the sweet beverage.
• When eating outdoors, try to keep food covered at all times.
• Garbage cans stored outside should be covered with tight-fitting lids.
• Avoid sweet-smelling perfumes, hair sprays, colognes and deodorants.
• Avoid wearing bright-colored clothing.
• Yard work and gardening should be done with caution. Wearing shoes and socks and using work gloves will prevent stings on hands and feet and provide time to get away from an unexpected mound.
• Keep window and door screens in good repair. Drive with car windows closed.
• Keep prescribed medications handy at all times and follow the instructions if you are stung. These medications are for immediate emergency use while en route to a hospital emergency room for observation and further treatment.

If you have had an allergic reaction to an insect sting, it’s important that you see an allergist.

Fire Ant Sting

Fire ant sting allergy treatment

Fire ant sting allergy is treated in a two-step approach:

• The first step is the emergency treatment of the symptoms of a serious reaction when they occur.
• The second step is preventive treatment of the underlying allergy with whole body extract immunotherapy.

Life-threatening allergic reactions can progress very rapidly and require immediate medical attention. Emergency treatment usually includes administration of certain drugs, such as epinephrine, antihistamines, and in some cases, corticosteroids, intravenous fluids, oxygen and other treatments. Once stabilized, these patients sometimes require close observation in the hospital overnight.

Injectable epinephrine is often prescribed as emergency rescue medication for treating an allergic reaction. People who have had previous allergic reactions and rely on epinephrine must remember to carry it with them at all times.

Also, because one dose may not be enough to reverse the reaction, recent guidelines recommend keeping two doses of injectable epinephrine available and to activate emergency medical services if used. Even if symptoms improve after a single dose of epinephrine, immediate medical attention following an insect sting is recommended.

What is a normal reaction to a fire ant sting, and how is it treated?

The severity of a fire ant sting reaction varies from person to person. One of the main differences between fire ants and other insects is that a usual sting event consists of multiple fire ants stinging. This is because when a fire ant mound is disturbed hundreds to thousands of fire ants respond. In addition, each ant can sting repeatedly. Each ant will bite and hold on with its mandibles (jaw) and sting several times. If not removed, this results in a little semi-circular pattern of stings. Since fire ants hold on with their mandibles, they often have to be pulled off individually and are not easily brushed off when they are stinging.

Almost all people stung by fire ants develop an itchy, localized hive or lump at the sting site, which usually subsides within 30 to 60 minutes. This is followed by a small blister within four hours. This usually appears to become filled with pus-like material by eight to 24 hours. However, what is seen is really dead tissue, and the blister has little chance of being infected unless it is opened. When healed, these lesions may leave scars.

Fire ant sting treatment is aimed at preventing secondary bacterial infection, which may occur if the pustule is scratched or broken. Clean the blisters with soap and water to prevent secondary infection. Do not break the blister. If a blister is accidentally opened, careful attention to keeping the area clean with soap and water should still prevent infection. Topical corticosteroid ointments and oral antihistamines may relieve the itching associated with these reactions.

symptoms, causes, types, treatment and complications – consultation of experienced dermatologists and allergists of the MEDSI clinic

Urticaria is an allergic disease (dermatosis), which is manifested by the formation of blisters on the skin and mucous membranes. Its symptoms, according to statistics, are experienced by about 25% of the world’s population. At the same time, only 2–7% are children, the rest are adults. The onset of the disease often occurs before the age of 40. Under the condition of constant contact with the allergen, the disease becomes chronic. Pathology is dangerous because it can cause Quincke’s edema.

Classification of diseases

Urticaria can be acute and chronic.

In the first case, it is manifested by the rapid (within one hour) appearance of numerous bright pink blisters. After some time, they either disappear completely, or a second wave sets in with the formation of new ones. Chronic urticaria is characterized by a long course. Moreover, it can occur not only in contact with an allergen, but also in diseases of the liver and digestive organs.

Also, depending on the location of the rash, the following forms of urticaria are distinguished:

• Localized. In this case, the rash forms only on certain parts of the body
• Generalized. Rash spread all over body

Depending on the causes, the following types of pathology are distinguished:

• Allergic urticaria
• Endocrine
• Solar
• Cold
• Medicinal
• Infectious
• Reactogenic etc.

Urticaria in children

This pathology is also called strofulus. It usually occurs in children who are breastfed or on an age-inappropriate diet. Insect bites, contact with allergens, infectious infections, and the appearance of parasites in the body can provoke the disease. Blisters in children quickly transform into pink-brown nodules with a small bubble. The affected skin itches and itchs. Often, bloody crusts form on it. Skin folds and limbs are often affected. Gradually, the rash can spread throughout the body. Babies under 3 years of age additionally develop symptoms such as diarrhea or constipation and vomiting. If the pathology becomes chronic, the child may become drowsy and lethargic, suffer from sleep disturbances and loss of appetite. Interestingly, after 7 years, almost all children have it without a trace.

Other types of diseases

Symptoms of urticaria in some women appear before menstruation, the cause of the pathology in this case is hormonal changes. Usually, formations are noticeable on the chest and in the face area. They do not cause pronounced discomfort, they can only cause slight swelling and slight itching.

There is also a toxic form of the disease. It occurs upon contact with certain insects, animals, fish, marine life (for example, jellyfish) and plants (including poisonous ones).

Chronic sluggish urticaria can develop in the presence of a pet.

Causes of disease

Urticaria in adults and children occurs against the background of:

• Insect bites
• Use of certain drugs
• Eating new food
• Vaccinations
• Blood transfusions
• Direct contact with allergen

A rash occurs as a result of a reaction to high temperatures or cold, vibration, exposure to ultraviolet radiation, mechanical friction, etc. Infectious agents (fungi, bacteria, etc.) also lead to the development of pathology. In about 30% of patients, it is not possible to find out the causes of urticaria.

Symptoms

The main signs of a pathological condition include:

• Rash on body
• Itching
• Transformation of rash into blisters

Usually the rash is concentrated on the limbs, face and scalp. In some cases, it also appears on the mucous membranes. In addition, the symptoms of urticaria include headache and drowsiness, a feeling of weakness and nausea. In some cases, patients complain of an increase in body temperature.

Important! With a favorable course, the symptoms disappear very quickly.

If the disease has acquired a chronic form, then it is characterized by less pronounced symptoms, but a long course.

Diagnostics

Before determining how to treat hives, a doctor needs to identify its symptoms and causes. Usually, the diagnosis is made on the basis of a survey of patients and a study of clinical manifestations. If necessary, identify the allergen. For this, special tests are carried out.

Methods of treatment of urticaria in children and adults

The most effective method of therapy is to eliminate contact with the allergen. If it cannot be detected, the patient is prescribed antihistamines that prevent the risks of developing the disease.

Treatment of acute urticaria

To quickly eliminate symptoms, not only antihistamines are recommended, but also avoiding contact with household chemicals, cosmetics, perfumes and other potentially hazardous substances. Patients are also prescribed a special diet. Thanks to it, it is possible to eliminate the risks of occurrence of factors that provoke unpleasant symptoms of the disease.

The diet is selected individually, while there are general principles.

These include an exception to the diet:

• Products that can provoke an allergic reaction
• Lots of protein food
• Products that are unknown to the patient and have not been previously tried by him
• Sauces and condiments
• Complex dishes with many components (especially unknown ones)
• Alcohol
• Spicy dishes
• Pickles and marinades

It is also important for the patient to limit the consumption of table salt and sugar, to use only fresh proven products for cooking.

Even with restrictions, you need to try to make the diet as diverse as possible. It is desirable to include in it: yellow or green (not red) apples, lean meat, mild cheese, grain bread, cabbage, herbs, white currants, peas, beans.

Important! It should be understood that an allergy can occur to almost any product. Therefore, they should be introduced into the diet in small portions and a special food diary should be kept, describing in it the reactions to the use of products.

Treatment of chronic urticaria

Therapy requires special attention from the doctor. He needs to carefully select the initial set of drugs. It is determined by the severity of the pathology and the symptoms of the disease. If a negative reaction occurs to any of the means, the reception is immediately stopped. It is also important to cleanse the intestines and remove potentially dangerous substances from the body.

Important! The patient needs to be prepared for the fact that the treatment of urticaria is often delayed for months. In this case, there is always a chance that all symptoms will suddenly disappear.

Treatment of urticaria in children

The therapy is carried out in the same way as in adults. Special preparations are prescribed to reduce the body’s sensitivity to the allergen, remove the skin reaction and ensure the prevention of exacerbations.

Important! If necessary, gastroenterologists, gynecologists and other narrow specialists are involved in the treatment of urticaria in adults and children. This is due to the fact that in some cases the pathology develops against the background of diseases of internal organs and systems and requires an integrated multidisciplinary approach.

1. Use antihistamines before vaccination and local anesthesia
2. Keep a food diary

Urticaria is an allergic disease, the causes of which in children and adults can be very different. The main symptom of the disease is the appearance on the skin of rashes in the form of blisters, which are very itchy and resemble a nettle burn.

According to statistics, 25% of the entire population of the planet at least once in their life faced with this pathology, mostly children, women under the age of 40 years. With constant contact with the allergen, the disease becomes chronic, and in half of all cases it is accompanied by Quincke’s edema.

Causes of urticaria

Urticaria never develops on its own, there must be a reason for this. In some cases, it is not difficult to identify it, but sometimes it is difficult to do so.

Most often, urticaria in children occurs after the use of certain drugs in the treatment or the consumption of certain foods. The most allergenic for babies are honey, nuts, fish, food additives in foods, spices, sausages, semi-finished products. Therefore, they are not recommended for children under 3 years of age.

Also provoking factors include:

• insect bites;
• the presence of parasites in the body;
• plant pollen;
• mold;
• chemicals, including household chemicals;
• latex;
• ultraviolet;
• vibration.

However, it is not always possible to find out what exactly the patient developed allergic urticaria for. In about a third of all patients with this diagnosis, the causes of the disease, even after numerous tests and analyzes, remain unknown.

Urticaria symptoms

The main manifestation is the appearance on the skin of spots of red or pink color, of various shapes, and blisters, the size of which can reach several centimeters. A slight swelling may appear, which gradually disappears during the day, rarely two.

If the swelling affects the deeper layers of the skin or mucous membranes, angioedema may occur – a life-threatening condition that requires immediate medical attention.

Allergic urticaria rash is always accompanied by unbearable itching, and some patients describe it as an unbearable burning sensation. Violent combing of such areas can lead to infection of the epidermis with a further complication in the form of pustules and wounds.

Minor manifestations of urticaria include:

• headache;
• fever;
• sleep disorder;
• anxiety;
• loss of appetite.

According to the nature of the course, an allergic disease is divided into two types.

Acute urticaria is the most commonly diagnosed. Blisters and puffiness of the skin with this form appear quite suddenly, sometimes against the background of a person’s well-being. Most often caused by some external causes, food. It also happens after the use of drugs, especially when self-medicating. Symptoms resolve on their own within a few days to a few weeks.

Chronic urticaria is a condition in which symptoms persist for more than 6 weeks from the first skin rash. This variant is characterized by an undulating course, when periods of complete absence of symptoms (recovery) are abruptly replaced by exacerbations with the appearance of a new portion of spots and blisters. This is accompanied by unbearable itching and the rapid development of Quincke’s edema. The elements of the rash that appear can merge with each other, covering more and more new areas of the skin.

Sometimes periods of complete well-being without symptoms can last for a long time – up to 10 years.

Children’s urticaria is an allergic skin disease that most often develops against the background of an already existing exudative diathesis and appears due to foods introduced as complementary foods.

It has been observed that this type of allergy mainly develops in babies who are bottle-fed or eat foods that are not appropriate for their age.

Complications of urticaria

It is important to know what urticaria looks like and to be able to properly provide first aid. This will help prevent the development of serious complications that can lead to death.

Urticaria is often accompanied by Quincke’s edema, which is also called angioedema. Its development in the larynx is especially dangerous, as it can compress the trachea and disrupt breathing.

Another serious complication is anaphylactic shock. This is a life-threatening allergic reaction of the immediate type, which occurs when the human body is hypersensitive to a particular allergen. It usually develops upon repeated contact with the allergen and requires immediate medical attention.

Diagnosis of urticaria

Before starting treatment, it is important to understand what exactly a person has such a strong allergic reaction to. Only by removing this provocative factor from habitual life, one can not be afraid that the symptoms of urticaria will appear again, and this is possible even after the correct therapy has been carried out.

Most often, this type of allergy appears on food. It is possible to establish from what exactly the rash appeared by a blood test: the level of IgE antibodies to a mixture of food allergens is detected. First of all, you need to diagnose the presence of an allergic reaction to:

• nuts;
• vegetables and legumes;
• citrus fruits and fruits;
• seafood;
• cereal and sesame flour;
• fruits and gourds;
• infant formula;
• fish;
• meat;
• mushrooms;
• leaf tea;
• goat milk.

In addition to food, allergic manifestations can also be on other substances that surround us in life almost everywhere:

• molds;
• pollen from early flowering trees;
• pollen from late flowering trees;
• weed pollen;
• epithelium of domestic animals;
• house dust;
• house dust mite;
• poultry feather.

To identify the exact type of allergen, allergy tests are carried out for certain foods. It often happens that rashes appear due to seasonings and herbs used in cooking: paprika, cumin, cloves, basil, ginger, tarragon, thyme, marjoram, dill, bay leaf, black pepper, vanilla.

Some fish species may also be allergenic: cod, halibut, mackerel, and squid meat. But sometimes an allergic reaction in the form of hives develops on such familiar products as:

• cucumber;
• apricot;
• cherry;
• tomato;
• plum;
• grapes;
• persimmon;
• carrots;
• beets;
• watermelon.

All tests are carried out only by a specialist laboratory assistant. It is impossible to independently determine the presence of an allergy in the form of urticaria to a particular food or substance. This can be life-threatening, as it is possible to develop not only Quincke’s edema, but also anaphylactic shock.

First aid for urticaria

It is important that allergy medications are always in the home first aid kit, since urticaria in adults, and in a child, too, can appear at any time. Allergy medications can be in the form of drops or tablets. Modern drugs do not cause drowsiness and they have virtually no side effects.

Doctors recommend having Fenistil drops in the home medicine cabinet to eliminate urticaria and itching, which can be used from childhood, Erius tablets, which have a long antihistamine effect after taking, Loratadine, which helps to cope with Quincke’s edema, which often accompanies urticaria.

It is important to take the medicine at the first symptoms, without waiting for the general condition to worsen. If after 20 minutes from the moment of admission there was no improvement, you should call an ambulance.

Urticaria treatment

The only way to get rid of the disease is to avoid contact with the allergen, which is previously detected by laboratory tests. If the testing did not reveal a provocative factor, and the urticaria is episodic, then taking antihistamines will quickly eliminate the symptoms.

During treatment, it is recommended to follow a diet that will help prevent the recurrence of the disease in case of urticaria. The menu should include only hypoallergenic foods: lean boiled meat, soups with secondary meat broth or vegetarian. From cereals it is better to choose rice, buckwheat, oatmeal. Low-fat cottage cheese, natural yogurt, apples, dried fruit compote, with the exception of raisins, whole grain bread are recommended.

Citrus fruits, nuts, fish and all seafood, chocolate products, smoked meats, coffee, eggs, honey, store-bought muffins should be excluded from the menu for the duration of treatment.

Treatment is carried out by a dermatologist and an allergist-immunologist. For topical application, urticaria ointments will be effective, which not only relieve itching, but also eliminate swelling, redness and burning sensation on the skin. One of the most effective is Dimetinden gel, which must be applied in a thin layer to the affected area of ​​the skin up to 4 times a day.

A course of antihistamines is prescribed in the form of tablets. Also, the doctor may prescribe calcium gluconate or calcium chloride preparations for hives. They help to reduce the manifestations of allergies, but they should only be administered under the supervision of a doctor in the treatment room.

If antihistamines do not respond quickly, or for severe urticaria, corticosteroids are used, which can be applied to the skin or taken as a tablet or injection.

How long does it take to cure urticaria

Within 4-6 weeks, acute urticaria disappears in almost all patients with this diagnosis.
