What is allergic rhinitis?

Nasal allergy symptoms and hay fever are referred to as “allergic rhinitis.” Seasonal allergic rhinitis is nasal allergies that change with the seasons because of pollen from plants (trees, grasses, or weeds). Seasonal symptoms arise during the pollinating seasons for specific plants. Because you can be allergic to more than one thing, your symptoms may get worse at diverse times throughout the year, or may be constant.

What are the types of allergies and how are they treated?

People can be allergic to a wide variety of substances; the most common are pollen and dust mites. Other airborne allergens include molds and animal dander.

Mold Allergy

How Can I Prevent an Allergic Reaction to Mold?

There is no cure for allergies. But you can reduce your allergy symptoms by avoiding contact with the mold spores. Several measures will help:

Reduce Your Exposure to Mold Spores Outside

  1. Limit your outdoor activities when mold counts are high.

    What causes allergies inside home

    This will lessen the quantity of mold spores you inhale and your symptoms.

  2. Wear a dust mask when cutting grass, digging around plants, picking up leaves and disturbing other plant materials.

Reduce Your Exposure to Mold Spores Inside

  1. Lower your indoor humidity. No air cleaners will assist if excess moisture remains. If indoor humidity is above 50%, fungi will thrive. A hygrometer is a tool used to measure humidity. The goal is to hold humidity under 45%, but under 35% is better.

    If you own to use a humidifier, clean the fluid reservoir at least twice a week to prevent mold growth.

    Air conditioners and dehumidifiers can also be a source of mold.

  2. Use central air conditioning with a CERTIFIED asthma & allergy friendly® filter attachment. This can assist trap mold spores from your entire home. Freestanding air cleaners only filter air in a limited area. Avoid devices that treat air with heat, electrostatic ions or ozone.
  3. Prevent mold and mildew build up inside the home. Pay shut attention to mold in bathrooms, basements and laundry areas. Be aggressive about reducing dampness.

To Reduce Mold in Your Bathrooms:

  1. Remove bathroom carpeting from places where it can get wet.
  2. Scour sinks and tubs at least monthly.

    Fungi thrive on soap and other films that jacket tiles and grout.

  3. Use an exhaust fan or open a window in the bathroom during baths and showers.
  4. Quickly repair any plumbing leaks.

To Reduce Mold in Your Kitchen:

  1. Clean refrigerator door gaskets and drip pans.
  2. Quickly repair any plumbing leaks.
  3. Clean trash pails frequently.
  4. Use an exhaust fan when you are cooking or washing dishes.

To Reduce Mold in Your Laundry Area:

  1. If you own a front-loading washing machine, clean the rubber seal and inside of the door.

    Leave the door cracked open when the machine is not in use.

  2. Don’t leave wet, damp clothes sitting around.
  3. Remove clothes from washing machine promptly.
  4. Make certain your laundry area has excellent air circulation.

To Reduce Mold in Your Bedrooms:

  1. Throw away or recycle ancient books, newspapers, clothing or bedding.
  2. Check windows for condensation (water droplets or mist).
  3. Polyurethane and rubber foams seem especially prone to fungus invasion. Use plastic covers on bedding made from these foams.
  4. Improve air flow through your bedroom. If your closet is colder than the relax of your room, leave the closet doors open.

To Reduce Mold in Your Basement:

  1. Quickly repair any plumbing leaks.
  2. Promote ground water drainage away from a home.

    Remove leaves and dead vegetation near the foundation and in the rain gutters.

To Reduce Mold in Your Whole House:

  1. Increase air flow in your home. Open doors between rooms, move furniture away from walls and use fans if needed.
  2. Use an electric dehumidifier to remove moisture and hold humidity in your home under 45 percent. Drain the dehumidifier regularly and clean the condensation coils and collection bucket.
  3. Repair roof leaks and roof gutters.

    Clean out your gutters to remove leaves and debris. When gutters are full or damaged, it can cause leaking.

How common are allergies?

More than 50 million Americans (1 in 6) suffer from every types of allergies, including indoor/outdoor allergies, food and drug, latex, insect, skin and eye allergies. The number of people who own allergies continues to increase across every ages, sex, and racial groups.

What Are the Symptoms of a Mold Allergy?

The symptoms of mold allergy are extremely similar to the symptoms of other allergies, such as sneezing, itching, runny nose, congestion and dry, scaling skin.

  1. Outdoor molds may cause allergy symptoms in summer and drop (or year-round in some climates)
  2. Indoor molds may cause allergy symptoms year-round

Mold spores get into your nose and cause hay fever symptoms.

They also can reach the lungs and trigger asthma. A chemical released by allergy cells in the nose and or lungs causes the symptoms. Sometimes the reaction happens correct away. Sometimes a mold allergy can cause delayed symptoms, leading to nasal congestion or worsening asthma over time. Symptoms often get worse in a damp or moldy room love a basement. This may mean you own a mold allergy.

Rarely, some patients can own a more serious illness called allergic bronchopulmonary aspergillosis. In this condition, there is both an allergic and an inflammatory response to the mold. Symptoms may include severe wheezing, coughing and shortness of breath, much love asthma.

Food fungi, love mushrooms, dried fruit, or foods containing yeast, vinegar or soy sauce, generally don’t cause allergy symptoms of the nose, eyes and lungs.

It is more likely that reactions to food fungi are caused by the food’s direct effect on blood vessels. For example, fermented foods (like wine) may naturally contain a substance known as histamine. Histamine is also a chemical your allergy cells release during an allergic reaction. Foods that contain histamines can trigger allergy-like responses when you consume them.

Does everyone get allergies?

No. Most allergies are inherited, which means they are passed on to children by their parents. People inherit a tendency to be allergic, although not to any specific allergen.

If a kid develops an allergy, it is extremely likely that at least one of his or her parents has allergies.

What Is a Mold Allergy?

If you own an allergy that occurs over several seasons, you may be allergic to the spores of molds or other fungi. Molds live everywhere. Upsetting a mold source can send the spores into the air.

Mold and mildew are fungi. They are diverse from plants or animals in how they reproduce and grow. The “seeds,” called spores, travel through the air.

Some spores spread in dry, windy weather. Others spread with the fog or dew when humidity is high.

Inhaling the spores causes allergic reactions in some people.

What causes allergies inside home

Allergic symptoms from fungus spores are most common from July to early drop. But fungi grow in numerous places, both indoors and exterior, so allergic reactions can happen year round.

Although there are numerous types of molds, only a few dozen cause allergic reactions. Numerous molds grow on rotting logs and fallen leaves, in compost piles and on grasses and grains. Unlike pollens, molds do not die with the first killing frost. Most outdoor molds become inactive during the winter.

In the spring they grow on plants killed by the freezing. Indoors, fungi grow in damp areas. They can often be found in the bathroom, kitchen or basement.

Treatments that are not recommended for allergic rhinitis

  1. Antibiotics: Effective for the treatment of bacterial infections, antibiotics do not affect the course of uncomplicated common colds (a viral infection) and are of no benefit for noninfectious rhinitis, including allergic rhinitis.
  2. Nasal surgery: Surgery is not a treatment for allergic rhinitis, but it may assist if patients own nasal polyps or chronic sinusitis that is not responsive to antibiotics or nasal steroid sprays.

Misery loves comfort, and with approximately 50 million Americans plagued by seasonal allergies, there are plenty of people feeling miserable and seeking comfort when pollen is in the air.

But in an attempt to relieve their sneezing, stuffy or runny noses, and itchy eyes, allergy sufferers might make a few mistakes.

The excellent news is that «seasonal allergies are totally treatable,» said Dr.

Clifford Bassett, medical director of Allergy and Asthma Care of New York. «The key is to own a plan in place.»

Bassett described seven common mistakes that people with seasonal allergies make, so you can know to avoid them.

Mistake 1: Spending unwisely on over-the-counter medications

When people with allergies feel lousy, they may head to the drugstore and attempt a variety of products, such as antihistamines, nasal sprays and eye drops. This isn’t necessarily a brilliant or cost-effective way to relieve their symptoms, though. It’s better to see an allergist who can pinpoint exactly what your allergies are and create an allergy action plan, said Bassett, a fellow of the American College of Allergy, Asthma and Immunology.

[9 Weirdest Allergies]

Mistake 2: Opening the windows

«Wind is not a excellent friend to people with seasonal allergies,» Bassett told Live when the weather gets warm, it’s tempting to let unused air and cool breezes into your home or car. «This is a large error for people with seasonal allergies because this allows pollens to visit,» Bassett said. He recommends keeping windows shut, running the air conditioner to recirculate inside air and using HEPA (high-efficiency particulate air) filters to trap pollen.

Mistake 3: Not taking steps to hold pollen away

Your shoes, clothes, hair and glasses can every track pollen from exterior into your home.

Pets also bring pollen inside, so hold them clean. You should hold your own hair clean, too. «Wash hair at the finish of the day to avoid transferring pollen to your pillowcase and sleeping on a pollen cloud,» Bassett advised. It can also assist to use saline nasal sprays, which are love a shower for your nose, to gently irrigate pollen from it, Bassett said. He also recommended that people avoid hanging laundry on an outdoor clothesline during allergy season.

Mistake 4: Neglecting your eyes

Many people don’t realize that lots of pollen enters the body through the eyes, Bassett said.

Protecting your eyes offers a grand chance to reduce the pollen load your body experiences, he said. A brimmed cap and sunglasses can assist block pollens from your face before they discover their way into your nose and eyes. Eye rinses can wash away pollen, and antihistamine eye drops can relieve red, itchy eyes.

Mistake 5: Waiting too endless to take allergy medications

Treat allergies at the onset of pollen season, rather than waiting until symptoms get more severe, Bassett said. He advises his patients to start taking their medications one or two weeks before their allergy season typically begins. A proactive approach works better for numerous people; it may reduce the severity of symptoms, and the patient may finish up needing less medication, Bassett explained.

Mistake 6: Overusing nasal sprays

People should generally limit their use of over-the-counter nasal decongestant spray to a maximum of five days in a row; otherwise the spray may irritate the lining of the nose and sinuses.

With too much use, these sprays can make the nose severely congested, and some people just hold squirting in more spray to ease the stuffiness. «Rebound congestion creates symptoms worse than the original problem,» Bassett said.

Mistake 7: Eating foods that aggravate allergies.

When some people with pollen allergies eat certain unused fruits and vegetables, it may result in an itchy mouth or throat.

This is known as oral allergy syndrome. The allergic cross-reaction occurs shortly after the offending food is eaten. It happens because the immune system recognizes a similarity between proteins in some pollens and those in fruits, vegetables, nuts and spices. For example, a person with a birch pollen allergy may develop oral allergy symptoms after eating an apple, carrot, peach, almond or hazelnut. Sometimes peeling, cooking or avoiding the food altogether during allergy season may prevent symptoms, Bassett said.

What are allergies?

Allergies are your body's reaction to a substance it views as a harmful “invader.” For example, coming into contact with what is normally a harmless substance, such as pollen, might cause the immune system (the body's defense system) to react.

Substances that cause these reactions are called allergens.

What are dust mites?

Dust mites are tiny creatures that frequently make their home in places love furniture, carpets, and bedding. They are too little to be seen without a microscope or magnifying glass. They own eight legs and are not true insects, but relatives of spiders.

Dust mites feed on the flakes of skin shed by humans (and animals) every day. They prefer environments with 70 to 80% humidity, and temperatures of 68 to 77°F.

How can I get rid of dust mites?

In most parts of the world, it’s impossible to completely eliminate dust mites from your home.

However, you can take steps to minimize your exposure to dust mite allergens by keeping your home as dust-free as possible.

Vacuuming and dusting are not enough to remove dust mites, because these creatures can live deep inside your upholstery, mattresses, carpets, etc. You can cover mattresses, pillows, and upholstered furniture with zippered dust-proof covers – the material of these covers is designed with pores that are too little for dust mites to pass through. Wash sheets, blankets and other bedding every week in boiling water (no more than °F) to kill dust mites. Replace carpeting with hard flooring and avoid plush rugs, fabric draperies, and anything else that cannot easily be washed regularly.

Use a dehumidifier to reduce the humidity in your home under 50%, making it a less suitable environment for dust mites.

Clean hard surfaces with a wet mop or cloth to avoid stirring dry allergens up into the air.

Use HEPA filters to trap dust mites and other allergens.

Change the filters every three months to ensure they remain effective.

Avoidance

The first approach in managing seasonal or perennial forms of hay fever should be to avoid the allergens that trigger symptoms.

Outdoor exposure

  1. Wear glasses or sunglasses when outdoors to minimize the quantity of pollen getting into your eyes.
  2. Wear a pollen mask (such as a NIOSH-rated 95 filter mask) when mowing the lawn, raking leaves or gardening, and take appropriate medication beforehand.
  3. Don’t hang clothing outdoors to dry; pollen may cling to towels and sheets.
  4. Avoid using window fans that can draw pollens and molds into the house.
  5. Stay indoors as much as possible when pollen counts are at their peak, generally during the midmorning and early evening (this may vary according to plant pollen), and when wind is blowing pollens around.
  6. Try not to rub your eyes; doing so will irritate them and could make your symptoms worse.

Indoor exposure

  1. Reduce exposure to dust mites, especially in the bedroom.

    Use “mite-proof” covers for pillows, comforters and duvets, and mattresses and box springs. Wash your bedding frequently, using boiling water (at least degrees Fahrenheit).

  2. To limit exposure to mold, hold the humidity in your home low (between 30 and 50 percent) and clean your bathrooms, kitchen and basement regularly. Use a dehumidifier, especially in the basement and in other damp, humid places, and empty and clean it often.

    If mold is visible, clean it with mild detergent and a 5 percent bleach solution as directed by an allergist.

  3. Keep windows closed, and use air conditioning in your car and home.

    What causes allergies inside home

    Make certain to hold your air conditioning unit clean.

  4. Clean floors with a damp rag or mop, rather than dry-dusting or sweeping.

Exposure to pets

  1. If you are allergic to a household pet, hold the animal out of your home as much as possible. If the pet must be inside, hold it out of the bedroom so you are not exposed to animal allergens while you sleep.
  2. Wash your hands immediately after petting any animals; wash your clothes after visiting friends with pets.
  3. Close the air ducts to your bedroom if you own forced-air or central heating or cooling.

    Replace carpeting with hardwood, tile or linoleum, every of which are easier to hold dander-free.

What are the symptoms of dust mite allergy?

Some common dust mite allergy symptoms include sneezing, runny nose, irritated eyes, scratchy throat, coughing, wheezing, and shortness of breath.

These same symptoms can be caused by a variety of other allergens as well, so consult your allergist for testing.

What else gets into dust that might cause allergies?

The dust in your home may contain pet hair and dander, mold or pollen spores, and dust mite or cockroach body parts and droppings, every of which are common allergens. These allergens can cause an allergic reaction when you inhale or come into contact with them.

Medications

Many allergens that trigger allergic rhinitis are airborne, so you can’t always avoid them.

If your symptoms can’t be well-controlled by simply avoiding triggers, your allergist may recommend medications that reduce nasal congestion, sneezing, and an itchy and runny nose. They are available in numerous forms — oral tablets, liquid medication, nasal sprays and eyedrops. Some medications may own side effects, so discuss these treatments with your allergist so they can assist you live the life you want.

Insect venom (stings)

In a bee sting, the bee generally injects a sac of venom and may leave a stinger in the victim's skin. If the stinger is still in the skin, gently scrape it out with a fingernail or a stiff-edged object love a credit card.

Do not tug on the stinger, as this will cause the release of more venom into the skin.

A normal reaction will result in pain, swelling, and redness around the sting site. A large, local reaction may happen that will result in swelling that extends beyond the sting site. For example, a person stung on the ankle may own swelling of the leg.

The most serious reaction to an insect sting is an allergic one, which needs immediate medical attention. Symptoms of an allergic reaction to an insect sting include:

  1. Wheezing or difficulty swallowing.
  2. Swelling of the face, throat, or mouth tissue.
  3. Restlessness and anxiety.
  4. Rapid pulse.
  5. Generalized (widespread) hives that appear as a red, itchy rash that spreads to areas other than the area that was stung.
  6. Difficulty breathing.
  7. Dizziness or a sharp drop in blood pressure.

If the patient has a reaction love this, a re-sting can cause a serious reaction that can be life-threatening.

An allergic reaction is treated with epinephrine (adrenaline).

Anyone who has had allergic reactions from bee stings should be seen by a board-certified allergy/immunology doctor to confirm by skin and/or blood testing to bee venom that they own an allergy. Venom immunotherapy is recommended when venom allergy is confirmed. This will assist reduce the possibility that a re-sting will cause a serious reaction.

What are the symptoms of allergies?

Allergy symptoms can be classified as mild, moderate, or severe:

  1. Moderate reactions include symptoms that spread to other parts of the body.

    Symptoms may include itchiness, hives, and/or swelling, and trouble breathing.

  2. Mild reactions include local symptoms (affecting a specific area of the body) such as a rash or hives; itchiness, watery/red eyes, hay fever, and runny nose.

    What causes allergies inside home

    Mild reactions do not spread to other parts of the body.

  3. A severe allergic reaction, known as anaphylaxis, is a rare, life-threatening emergency in which the body's response to the allergen is sudden and affects the whole body. Anaphylaxis may start with severe itching of the eyes or face. Within minutes, more serious symptoms appear, including throat swelling (which could cause problems with swallowing and breathing); abdominal pain; cramps; vomiting; diarrhea; hives; and swelling (angioedema).

    The person may also own mental confusion or dizziness, since anaphylaxis may cause a drop in blood pressure.

Decongestants

Decongestants assist relieve the stuffiness and pressure caused by swollen nasal tissue. They do not contain antihistamines, so they do not cause antihistaminic side effects. They do not relieve other symptoms of allergic rhinitis. Oral decongestants are available as prescription and nonprescription medications and are often found in combination with antihistamines or other medications.

It is not unusual for patients using decongestants to experience insomnia if they take the medication in the afternoon or evening. If this occurs, a dose reduction may be needed. At times, men with prostate enlargement may encounter urinary problems while on decongestants. Patients using medications to manage emotional or behavioral problems should discuss this with their allergist before using decongestants. Patients with high blood pressure or heart disease should check with their allergist before using. Pregnant patients should also check with their allergist before starting decongestants.

Nonprescription decongestant nasal sprays work within minutes and final for hours, but you should not use them for more than a few days at a time unless instructed by your allergist.

Prolonged use can cause rhinitis medicamentosa, or rebound swelling of the nasal tissue. Stopping the use of the decongestant nasal spray will cure that swelling, provided that there is no underlying disorder.

Oral decongestants are found in numerous over-the-counter (OTC) and prescription medications, and may be the treatment of choice for nasal congestion. They don’t cause rhinitis medicamentosa but need to be avoided by some patients with high blood pressure. If you own high blood pressure or heart problems, check with your allergist before using them.

Immunotherapy

Immunotherapy may be recommended for people who don’t reply well to treatment with medications or who experience side effects from medications, who own allergen exposure that is unavoidable or who desire a more permanent solution to their allergies.

Immunotherapy can be extremely effective in controlling allergic symptoms, but it doesn’t assist the symptoms produced by nonallergic rhinitis.

Two types of immunotherapy are available: allergy shots and sublingual (under-the-tongue) tablets.

  1. Allergy shots: A treatment program, which can take three to five years, consists of injections of a diluted allergy extract, istered frequently in increasing doses until a maintenance dose is reached. Then the injection schedule is changed so that the same dose is given with longer intervals between injections.

    Immunotherapy helps the body build resistance to the effects of the allergen, reduces the intensity of symptoms caused by allergen exposure and sometimes can actually make skin test reactions vanish. As resistance develops over several months, symptoms should improve.

  2. Sublingual tablets: This type of immunotherapy was approved by the Food and Drug istration in Starting several months before allergy season begins, patients dissolve a tablet under the tongue daily. Treatment can continue for as endless as three years. Only a few allergens (certain grass and ragweed pollens and home dust mite) can be treated now with this method, but it is a promising therapy for the future.

Antihistamines

Antihistamines are commonly used to treat allergic rhinitis.

These medications counter the effects of histamine, the irritating chemical released within your body when an allergic reaction takes put. Although other chemicals are involved, histamine is primarily responsible for causing the symptoms. Antihistamines are found in eyedrops, nasal sprays and, most commonly, oral tablets and syrup.

Antihistamines assist to relieve nasal allergy symptoms such as:

  1. Eye itching, burning, tearing and redness
  2. Sneezing and an itchy, runny nose
  3. Itchy skin, hives and eczema

There are dozens of antihistamines; some are available over the counter, while others require a prescription.

Patients reply to them in a wide variety of ways.

Generally, the newer (second-generation) products work well and produce only minor side effects. Some people discover that an antihistamine becomes less effective as the allergy season worsens or as their allergies change over time. If you discover that an antihistamine is becoming less effective, tell your allergist, who may recommend a diverse type or strength of antihistamine. If you own excessive nasal dryness or thick nasal mucus, consult an allergist before taking antihistamines.

Contact your allergist for advice if an antihistamine causes drowsiness or other side effects.

Proper use: Short-acting antihistamines can be taken every four to six hours, while timed-release antihistamines are taken every 12 to 24 hours. The short-acting antihistamines are often most helpful if taken 30 minutes before an anticipated exposure to an allergen (such as at a picnic during ragweed season). Timed-release antihistamines are better suited to long-term use for those who need daily medications. Proper use of these drugs is just as significant as their selection. The most effective way to use them is before symptoms develop.

A dose taken early can eliminate the need for numerous later doses to reduce established symptoms. Numerous times a patient will tell that he or she “took one, and it didn’t work.” If the patient had taken the antihistamine regularly for three to four days to build up blood levels of the medication, it might own been effective.

Side effects: Older (first-generation) antihistamines may cause drowsiness or performance impairment, which can lead to accidents and personal injury.

Even when these medications are taken only at bedtime, they can still cause considerable impairment the following day, even in people who do not feel drowsy. For this reason, it is significant that you do not drive a car or work with dangerous machinery when you take a potentially sedating antihistamine. Some of the newer antihistamines do not cause drowsiness.

A frequent side effect is excessive dryness of the mouth, nose and eyes. Less common side effects include restlessness, nervousness, overexcitability, insomnia, dizziness, headaches, euphoria, fainting, visual disturbances, decreased appetite, nausea, vomiting, abdominal distress, constipation, diarrhea, increased or decreased urination, urinary retention, high or low blood pressure, nightmares (especially in children), sore throat, unusual bleeding or bruising, chest tightness or palpitations.

Men with prostate enlargement may encounter urinary problems while on antihistamines. Consult your allergist if these reactions occur.

Important precautions:

  1. Keep these medications out of the reach of children.
  2. Know how the medication affects you before working with heavy machinery, driving or doing other performance-intensive tasks; some products can slow your reaction time.
  3. Some antihistamines appear to be safe to take during pregnancy, but there own not been enough studies to determine the absolute safety of antihistamines in pregnancy.

    Again, consult your allergist or your obstetrician if you must take antihistamines.

  4. While antihistamines own been taken safely by millions of people in the final 50 years, don’t take antihistamines before telling your allergist if you are allergic to, or intolerant of, any medicine; are pregnant or intend to become pregnant while using this medication; are breast-feeding; own glaucoma or an enlarged prostate; or are ill.
  5. Do not use more than one antihistamine at a time, unless prescribed.
  6. Alcohol and tranquilizers increase the sedation side effects of antihistamines.
  7. Follow your allergist’s instructions.
  8. Never take anyone else’s medication.

Nasal sprays

Nonprescription saline nasal sprays will assist counteract symptoms such as dry nasal passages or thick nasal mucus.

Unlike decongestant nasal sprays, a saline nasal spray can be used as often as it is needed. Sometimes an allergist may recommend washing (douching) the nasal passage. There are numerous OTC delivery systems for saline rinses, including neti pots and saline rinse bottles.

Nasal cromolyn blocks the body’s release of allergy-causing substances. It does not work in every patients. The full dose is four times daily, and improvement of symptoms may take several weeks. Nasal cromolyn can assist prevent allergic nasal reactions if taken prior to an allergen exposure.

Nasal ipratropium bromide spray can assist reduce nasal drainage from allergic rhinitis or some forms of nonallergic rhinitis.

Certain foods

Food allergies develop when the body develops a specific antibody to a specific food.

An allergic reaction occurs within minutes of eating the food, and symptoms can be severe. In adults, the most common food allergies are shellfish, peanuts, and tree nuts; in children, they include milk, egg, soy, wheat, shellfish, peanuts, and tree nuts.

Symptoms of food allergy include itching, hives, nausea, vomiting, diarrhea, breathing difficulties, and swelling around the mouth.

The only treatment is to avoid the foods that cause allergy symptoms.

If you (or your child) own a food allergy, your doctor may prescribe injectable epinephrine (adrenaline) for you to carry at every times. This is necessary in case foods that cause allergies are accidently eaten.

Intranasal corticosteroids

Intranasal corticosteroids are the single most effective drug class for treating allergic rhinitis. They can significantly reduce nasal congestion as well as sneezing, itching and a runny nose.

Ask your allergist about whether these medications are appropriate and safe for you. These sprays are designed to avoid the side effects that may happen from steroids that are taken by mouth or injection. Take care not to spray the medication against the middle portion of the nose (the nasal septum).

The most common side effects are local irritation and nasal bleeding. Some older preparations own been shown to own some effect on children’s growth; data about some newer steroids don’t indicate an effect on growth.

Latex

Some people can develop a latex allergy after repeated contact with latex. Rubber gloves, such as those used in surgery or home cleaning, are a major source for causing this type of reaction. Skin rash, hives, eye tearing and irritation, wheezing, and itching of the skin may happen in people with latex allergy.

Allergic reactions to latex can be mild, such as skin redness and itching.

More severe reactions can happen if the mucosal membranes are exposed, such as during an operation or a dental or gynecologic exam.

Treatment of latex reactions begins by removing the offending latex product. If you own latex allergy, it is significant for you to wear a Medic Alert bracelet and carry an emergency epinephrine kit. Every procedures should be carried out in a “latex-safe” fashion. There is no cure for latex allergy, so the best treatment for this condition is prevention.

Pollen

Seasonal allergic rhinitis, or hay fever, is an allergic response to pollen.

It causes inflammation and swelling of the lining of the nose and of the protective tissue of the eyes (conjunctiva).

Symptoms include sneezing, congestion (feeling stuffy), and itchy, watery eyes. Treatment options include over-the-counter and prescription antihistamines, anti-leukotrienes, nasal steroids, and nasal cromolyn. Some people may own allergic asthma symptoms (wheezing, shortness of breath, chest tightness) caused by exposure to pollen.

Symptoms can be reduced by avoiding pollen.

Stay indoors when pollen counts are high, shut windows, and use air conditioning. Immunotherapy (“allergy shots”) also may be used to treat pollen allergy.

Molds

Molds are parasitic, tiny fungi (like Penicillium) with spores that float in the air love pollen. Mold is a common trigger for allergies. Mold can be found indoors in damp areas, such as the basement or bathroom, as well as outdoors in grass, leaf piles, hay, mulch, or under mushrooms. Mold spores reach a peak during boiling, humid weather.

Treatment may include medications to control nasal/eye and chest symptoms. Immunotherapy may be recommended for people whose symptoms are not adequately controlled with avoidance and medications.

Animal dander

Allergic reactions can be caused by the proteins secreted by sweat glands in an animal's skin, which are shed in dander, and (to a lesser extent) by the proteins in an animal's saliva.

Avoidance measures don’t work as well as simply removing the pet from the home. However, because numerous people are reluctant to do this, second-best measures include keeping the pet out of the bedroom, using air cleaners with HEPA filtration, and washing the pet (cat or dog) frequently.

Treatment may include medications to control nasal/eye and chest symptoms. Immunotherapy may be recommended for people whose symptoms are not adequately controlled with avoidance methods and medications.

Other allergens include:

Dust mites

Dust mites are tiny organisms that live in dust and in the fibers of household objects, such as pillows, mattresses, carpet, and upholstery.

Dust mites especially love warm, humid areas.

The symptoms of dust mite allergy are similar to those of pollen allergy. To assist manage dust mite allergies, attempt using dust mite encasements (airtight plastic/polyurethane covers) over pillows, mattresses, and box springs. Also, remove carpet, or vacuum frequently with a high-efficiency filter vacuum cleaner. Treatment may include medications to control nasal/eye and chest symptoms. Immunotherapy may be recommended for people whose symptoms are not adequately controlled with avoidance methods and medications.

Leukatriene pathway inhibitors

Leukotriene pathway inhibitors (montelukast, zafirlukast and zileuton) block the action of leukotriene, a substance in the body that can cause symptoms of allergic rhinitis.

These drugs are also used to treat asthma.

Eye allergy preparations and eyedrops

Eye allergy preparations may be helpful when the eyes are affected by the same allergens that trigger rhinitis, causing redness, swelling, watery eyes and itching. OTC eyedrops and oral medications are commonly used for short-term relief of some eye allergy symptoms. They may not relieve every symptoms, though, and prolonged use of some of these drops may actually cause your condition to worsen.

Prescription eyedrops and oral medications also are used to treat eye allergies. Prescription eyedrops provide both short- and long-term targeted relief of eye allergy symptoms, and can be used to manage them.

Check with your allergist or pharmacist if you are unsure about a specific drug or formula.

What is an allergic reaction?

An “allergic reaction” is the way the body responds to the allergen.

A chain of events happen that result in an allergic reaction.

The first time an allergy-prone person is exposed to a specific allergen (such as pollen), the body responds by producing allergic (IgE) antibodies. The occupation of these antibodies is to discover molecules of the offending substance in the bloodstream and tissues and to usher them to the body's mast cells (a type of white blood cell) for destruction. As the mast cells destroy the allergens, a chemical called histamine is released into the bloodstream.

A large quantity of histamine swells body tissues (inflammation), causes itching, enlarges blood vessels, increases secretions, and causes bronchospasm (tightening of muscles that surround the airways).
