What is the best allergy medicine for cat allergies over the counter

If your child’s allergies aren’t too severe, you may be capable to take some steps to reduce your child’s symptoms and hold your pet. For instance:

Keep pets out of the bedroom. Make your child’s room a pet-free zone and be certain to hold it clean. To hold the room pet dander- and pollen-free, install a high-efficiency air filter and air purifier. Remember to change the filters frequently.

Cover your child’s bed with additional protection. You can purchase dust mite covers for your child’s pillow, blanket, and mattress.

This will also assist hold out dust mites, another potential allergy trigger, in addition to allergens love pet dander.

Go for hard surfaces. Where you can, replace upholstered surfaces with non-fabric or easily washable materials. Pet dander sticks to upholstery, drapes, curtains, and carpeting more easily than it does to surfaces such as wood, vinyl, or tile. Plus, the latter are easier to clean. For this reason, you also shouldn’t let your allergic kid sleep with stuffed animals, Dr. Nassef adds. If you must own carpet in your child’s bedroom or elsewhere in your home, select a low-pile one and own it steam-cleaned regularly.

Bathe your pet weekly.

Weekly baths can significantly reduce the quantity of allergy-causing dander your pet sheds. If possible, enquire a non-allergic member of your household to bathe the pet and be certain to wash that person’s clothes afterward. Wearing gloves may also assist. Enquire your veterinarian to recommend the best soaps and shampoos. Caution: Bathing too frequently can own the opposite effect. It can dry your pet’s skin and cause the animal to shed more dander.

Teach your kid to wash his hands with soap and water after touching the pet. Washing helps prevent the spread of allergens to your child’s nose, eyes, and mouth — which is especially significant if your kid gets a rash from having been licked by your pet, Nassef says.

Talk to your allergist about treatment.

“Medications work for allergy symptoms regardless of the trigger — pollen, pet dander, etc.,” Nassef says. “But not every medications work equally well for every symptoms.” That’s why it’s significant to work with your doctor and tailor your child’s allergy medications to his or her symptoms.

Consult your veterinarian. Your veterinarian can recommend a diet for your pet that’s wealthy in vitamins and minerals, which can assist your pet’s skin retain its moisture and not shed as much. Love people, pets can benefit from omega-3 and omega-6 fatty acids, according to the Partnership for Animal Welfare in Greenbelt, Maryland.

Every family has to decide for themselves whether they can manage their children’s pet allergies with a cat or dog, Nassef says.

“The best solution for pet allergies is to not own a pet,» she says, «but numerous people consider pets part of their family and getting rid of the pet is out of the question.”

But at what cost?

Contrary to favorite belief, cat hair itself is not allergenic. The cause of allergy to cats is a protein called Fel d 1 emanating from sebum found in the sebaceous glands of cats. The protein attaches itself to dried skin, called dander, that flakes off and floats through the air when cats wash themselves. Although you may never be capable to eliminate every your allergy symptoms, following these suggestions can assist make living with your cat a more enjoyable experience.

  • Clean the cat box. Cat allergen is found in urine and is left in the litter box when your cat makes a deposit.

    To assist prevent allergic reactions to the litter box, use a brand of litter that is less dusty and own someone in the household who is not allergenic clean the box.

    Brush your cat in the fresh-air enclosure to prevent loose, allergen-carrying hair from dispersing through your home.

  • Get some unused air. Highly insulated homes trap allergens as well as heat, so open the windows to increase the ventilation in your home, and run window fans on exhaust. (But remember to always screen windows so kitty stays safely indoors.) Also, clean the air inside your home. Although nothing will remove every of the allergens present, running an air cleaner with a HEPA filter will help.

Bathing a cat was once believed to be helpful, tell Dr. Robert Zuckerman, an allergy and asthma specialist in Harrisburg, PA, but the cat would own to be washed almost daily. Instead, daily use of products such as Pals Quick Cleansing Wipes™ will remove saliva and dander from your cats hair and are less stressful for felines who prefer not to be rubbed in the tub.
  • Post-Nasal Drip.

  • Designate your bedroom as a cat-free zone. Start your program of allergen reduction by washing bedding, drapes and pillows. Better yet, replace them. Use plastic covers that are designed to prevent allergens from penetrating on your mattress and pillows. Allergen-proof covers are available from medical supply outlets. Dont expect results overnight. Cat allergens are one-sixth the size of pollens, and it may take months to reduce them significantly.
  • Look at the whole picture.

    Because allergies rarely come individually wrapped, other culprits, such as dust mites and pollen, may be causing reactions, too. An individual rarely has a single allergy, says Zuckerman. A cat owner may be capable to tolerate contact with the cat in winter, but when spring arrives, every the allergies together may prove unbearable.

Allegra and Zyrtec are both antihistamines, but is one more effective or less likely to cause sedation than the other?

Allegra has the lowest risk of sedation out of every antihistamines so is preferred if an antihistamine is needed for people working in safety-critical jobs.

Even though Zyrtec is times more likely to cause sedation than Allegra, it is still much less sedating than some older antihistamines such as promethazine.

Other differences:

  1. Several studies own found cetirizine (Zyrtec) to be more effective than fexofenadine (Allegra) at relieving symptoms of allergic rhinitis and urticaria, and it appears to own a longer duration of action.
  2. Studies own not compared the effects of Allegra and Zyrtec for conditions such as postnasal drip, but research suggests intranasal antihistamines such as azelastine are more effective.
  3. Allegra should not be taken with grapefruit juice.

    Zyrtec has no reported food interactions.

  4. Allegra works within two hours and Zyrtec works within one hour.
  5. Zyrtec and Allegra should not be taken at the same time, instead, if symptoms are persisting, it is better to take another drug with a diverse mechanism of action.

Allegra is a brand name for the drug fexofenadine and Zyrtec is a brand name for the drug cetirizine. Both fexofenadine and cetirizine are favorite antihistamines with numerous similarities but there are some significant differences.

Which is more sedating?

Allegra or Zyrtec?

Allegra (fexofenadine) and Zyrtec (cetirizine) are second-generation antihistamines. Second-generation antihistamines were first developed in the s to provide allergy relief without the unwanted side effect of sedation common to first-generation antihistamines such as promethazine and diphenhydramine. However, it soon became apparent that not every second-generation antihistamines were equal when it came to not causing drowsiness or affecting other thought processes. Cetirizine is significantly more likely than fexofenadine to cause drowsiness.

Fexofenadine (Allegra), even in dosages exceeding those recommended, is the least sedating of every second-generation antihistamines, so is considered the antihistamine of choice for people in safety-critical jobs such as airline pilots.

Which is more effective for Allergic rhinitis?

Trials own shown both Allegra (fexofenadine) and Zyrtec (cetirizine) are significantly more effective than placebo (a pretend pill) for reducing symptoms associated with allergic rhinitis, hay fever, and other allergies.

Trials own not consistently shown that one antihistamine is more effective than another; however, one trial reported cetirizine produced a 26% greater reduction in the number of allergic rhinitis symptoms at 12 hours and 14% greater reduction in symptoms overall compared with fexofenadine. Cetirizine also appeared more effective for symptoms such as runny nose, sneezing, itchy/watery eyes, and itchy nose, mouth or throat. Cetirizine was slightly more likely (%) than fexofenadine to cause drowsiness.

Another trial reported similar findings (33% greater reduction in allergic rhinitis symptoms) and also found cetirizine had a longer duration of effect.

Intranasal or ophthalmic (into the eye) antihistamines own a quicker onset of action than oral antihistamines (within about 15 minutes); however, they need to be istered several times daily. In people with allergic rhinoconjunctivitis and predominantly eye symptoms, ophthalmic antihistamines work much quicker (within 3 to 15 minutes) and are much more effective than any other form of treatment.

Intranasal antihistamines are as effective as intranasal cromolyn, intranasal nedocromil, and leukotriene modifiers in seasonal allergic rhinitis; however, are not as effective at relieving nasal congestion and other symptoms as intranasal glucocorticoids.

Allegra Vs Zyrtec for urticaria and other skin reactions

All second generation antihistamines, including Allegra and Zyrtec, are effective for acute and chronic urticaria, although more trials own been conducted in people with chronic urticaria.

What is the best allergy medicine for cat allergies over the counter

One trial found cetirizine to be more effective than fexofenadine at relieving symptoms in 97 patients with chronic urticaria with % of participants taking cetirizine reporting themselves as symptom-free after 28 days of treatment compared with only % of participants taking fexofenadine. Partial improvement was reported by % of people assigned cetirizine (% assigned fexofenadine) and % experienced no improvement with cetirizine (% with fexofenadine). No difference in side effects was noted between the two.

Allegra Vs Zyrtec for Postnasal Drip

Post nasal drip may happen for various reasons — allergies (particularly to dairy), colds or flu, various drugs (including birth control pills and high blood pressure tablets), freezing temperatures, bright lights, hormonal changes and spicy foods.

Thin postnasal drip secretions caused by allergies may be treated with antihistamines.

Second-generation antihistamines such as Allegra and Zyrtec may offer better relief than older-type antihistamines such as promethazine (older antihistamines tend to thicken post-nasal secretions). Intranasal antihistamines, such as azelastine, own a faster onset of action (15 minutes) and appear more effective than oral antihistamines although require more frequent istration. Other treatments include decongestants, cromolyn, and corticosteroid nasal sprays.

In the treatment of post nasal drip caused by nonallergic causes, oral second-generation antihistamines are not extremely effective.

However, the intranasal antihistamine azelastine is effective. Azelastine improves every rhinitis symptoms including nasal congestion, postnasal drip, sneezing and sleeping difficulty. The most common side effect is a metallic aftertaste; however, this is more likely at higher dosages and tends to dissipate with continued use.

Allegra Vs Zyrtec To Relieve Freezing Symptoms

Second-generation antihistamines (such as Allegra and Zyrtec) own limited effectiveness at relieving symptoms of freezing such as a runny nose and sneezing (only 45% of adults felt better after using them compared to 35% with placebo [a pretend pill]). Effects were only noticeable if used within the first two days of a freezing, use of antihistamines made no difference thereafter.

Allegra Vs Zyrtec: istration

The antihistamine effects of Allegra and Zyrtec final for at least 24 hours, therefore, they are both given once daily.

Fexofenadine, the athletic ingredient of Allegra works within two hours. Cetirizine, the athletic ingredient of Zyrtec works within one hour.

Allegra Vs Zyrtec: Side Effects, Interactions and Price

Side effects are generally mild with second-generation antihistamines and include a headache and rarely dry mouth, and nausea. Zyrtec is times more likely than Allegra to cause sedation; however, Zyrtec is still much less sedating than older antihistamines such as promethazine.

Side effects are generally mild with second-generation antihistamines and include a headache and rarely dry mouth, and nausea.

Every the second generation antihistamines currently on the market appear free from adverse cardiovascular effects. Few major interactions own been reported with either Allegra or Zyrtec; however, there is the possibility that side effects such as sedation, confusion, and mental alertness may be enhanced if given with other drugs with this side effect.

Grapefruit juice appears to decrease the rate and extent of absorption of fexofenadine (Allegra) by about 30%. Cetirizine (Zyrtec) has no reported interactions with grapefruit or grapefruit products.

More studies are needed to determine if there are any interactions between second generation antihistamines and herbal products and other types of food. Always speak with your doctor of pharmacist before using any drugs in combination.

Cost is similar for 30 Allegra and 30 Zyrtec tablets and both are available as generics.

Feeding cats a diet coated in a specially formulated egg powder product can neutralize the feline allergens that trigger symptoms in people, Purina scientists announced recently.

In a conversation with dvm, researchers explained that the major feline antigen present in cats' saliva is a protein called Fel d1, and while scientists don't know exactly what the protein does for the cat, they do know it's responsible for 95% of cat allergies in people-and that one in five people are allergic to cats.

What is the best allergy medicine for cat allergies over the counter

Every cats, even those that are hairless, produce Fel d1, although levels vary from cat to cat and in the same cat over the course of a year.

Here's what happens: When a cat grooms, it transfers Fel d1 from its saliva and sebaceous glands to its fur. The antigen then spreads into the environment attached to shed hair and dander. It's known to be fairly “sticky,” Purina folks tell, clinging with a vengeance to blankets, carpet and curtains in the home and even making its way into public places.

When a sensitive person comes into contact with Fel d1, the allergen binds with IgE molecules in the immune system, triggering mast cell degranulation and an immune response-the distress of sneezing, itching, watery eyes and so on.

Cat owners who talk to their doctors about these symptoms often hear that the best remedy is to get rid of the cat; in fact, 18% of cats that finish up in shelters are relinquished because of allergies, Purina representatives tell. Other allergy-control options include antihistamines, immunotherapy, meticulous cleaning, confinement of the cat to a limited area or some combination of the above. The problem: None of these solutions are especially appealing or foolproof.

Enter this new study by Purina. In a decade-long research effort recently published in Immunity, Inflammation and Disease, scientists found that the IgY molecule present in egg yolk (an antibody passed from hens to their chicks) can block specific sites on the Fel d1 molecule, keeping it from binding with IgE and thereby neutralizing the allergen.

When cats were fed a diet coated with a specially formulated egg powder product containing IgY, 97% of cats showed decreased levels of athletic Fel d1 on their hair and dander compared with baseline. On average, there was a 47% reduction of athletic Fel d1 on cats' hair after three weeks of feeding the diet, with a range of 33% to 71% reduction.

Purina scientists report that there was no difference in health parameters between the control cats and the cats eating the special diet, which seems to indicate that the product is safe for cats to consume.

They also emphasize that the egg product does not suppress or destroy Fel d1-that protein may frolic an significant role in cats' physiology. Rather, the product neutralizes its allergenic effects, which means there's a greater chance that allergen levels in the environment will stay under the threshold that would trigger symptoms in people.

“These allergens own created a huge barrier to cat ownership and may limit the loving interactions between cat lovers and cats,” says immunologist Ebenezer Satyaraj, PhD, director of molecular nutrition at Purina and lead investigator on the research.

“Our discovery has the potential to convert how people manage cat allergens.”

More results from the research will be shared by the Purina Institute, an organization that serves as the global voice of Purina's scientific communications, as they become available.

When youre rubbing itchy eyes and sneezing your way through anallergyflare-up, do you also feel muddled and fuzzy-headed sometimes? Numerous allergy sufferers describe an experience known as brain fog — a hazy, tired feeling that makes it hard to concentrate.

What is this phenomenon and why does it happen?

According to allergist and immunologist Mark Aronica, MD, that disconnected feeling is fatigue, and it’s caused by the inflammation that results when your body tries to counteract your allergy symptoms.

“People with allergies experience inflammation,” he says. “That inflammation leads to a congested nose, disrupted sleep patterns and not getting excellent rest.”

And, once the cycle starts, its sometimes self-perpetuating.

You can discover it hard to go about your daily routines.

The more fatigued you are, the more difficulty you’ll own performing well in school or work. It can also negatively impact your quality of life if you’re too tired to do things you would normally do.

Whats really happening?

Your body produces whats called cytokines whenever youre exposed to an allergen, such as pollen, grass or mold, Dr. Aronica says. (Contrary to favorite belief, the pollen in most flowers doesnt cause allergies, but floral scents can still cause problems for people with sensitive noses.)

Advertising Policy

Cytokines are are proteins that are part of your body’s immune response to foreign substances.

You also produce them when fighting infections caused by bacteria, viruses and colds.

The cytokine release causes inflammation in your nose, leading to congestion and narrowed airways.

If you own allergies, allergen exposure leads to ongoing inflammation.

What is the best allergy medicine for cat allergies over the counter

And nasal congestion and disturbed sleep combine to give you that fuzzy-headed feeling.

“Chronic inflammation from allergies can lead to that foggy feeling,” he says. “And, you’ll finish up not functioning well.”

Fighting the fog

If your allergies are acting up and you feel the fog rolling in, there are a few things you can do to assist stop the debilitating cycle of symptoms, inflammation and fatigue, Dr.

What is the best allergy medicine for cat allergies over the counter

Aronica says.

1. Limit your exposure.If you’re allergic to pollen or grasses, do your best to stay away from them. Stay indoors when theyre at their peak.Keep your windows closed if you own air conditioning. If you do spend time exterior for longer periods, take a shower and change your clothes correct away when you come in.

Advertising Policy

If you’re allergic to dust or mold, hold up with dusting and cleaning to hold them out of your home as much as possible.

2.

Take your medicine.Medication can assist curb your allergy symptoms. Oral antihistamines (medications that prevent you from responding to the histamines that cause inflammation) are readily available. They’re a temporary solution, but they are often effective.

Over-the-counter and prescription nasal sprays can also assist combat your allergy symptoms, Dr. Aronica says.

3. Get allergy shots.This is the strongest form of treatment for allergy symptoms.

Little injections of allergens under the skin can assist your body build up an immunity over time. The result is less frequent and less severe allergic rhinitis, Dr. Aronica says.

He adds that some allergy sufferers also discover relief with nasal lavage — a saline wash that cleans out the sinuses and nasal passages. Numerous people ister this type of wash with aneti pot to clear out lingering allergy symptoms.

Dr.

Aronica notes that other conditions besides allergies may cause fatigue and brain fog. If you own a sore throat, cough, fever or body aches,you could own a freezing or other illness and should take medications that will combat those symptoms.

Coping with an allergy to cats is nothing to sneeze at. Its a commitment. After every, shelters get cats for this reason every day. Hopefully, following these tips will make a world of difference.

In people with allergic rhinoconjunctivitis and predominantly eye symptoms, ophthalmic antihistamines work much quicker (within 3 to 15 minutes) and are much more effective than any other form of treatment. Intranasal antihistamines are as effective as intranasal cromolyn, intranasal nedocromil, and leukotriene modifiers in seasonal allergic rhinitis; however, are not as effective at relieving nasal congestion and other symptoms as intranasal glucocorticoids.

Allegra Vs Zyrtec for urticaria and other skin reactions

All second generation antihistamines, including Allegra and Zyrtec, are effective for acute and chronic urticaria, although more trials own been conducted in people with chronic urticaria.

One trial found cetirizine to be more effective than fexofenadine at relieving symptoms in 97 patients with chronic urticaria with % of participants taking cetirizine reporting themselves as symptom-free after 28 days of treatment compared with only % of participants taking fexofenadine. Partial improvement was reported by % of people assigned cetirizine (% assigned fexofenadine) and % experienced no improvement with cetirizine (% with fexofenadine). No difference in side effects was noted between the two.

Allegra Vs Zyrtec for Postnasal Drip

Post nasal drip may happen for various reasons — allergies (particularly to dairy), colds or flu, various drugs (including birth control pills and high blood pressure tablets), freezing temperatures, bright lights, hormonal changes and spicy foods.

Thin postnasal drip secretions caused by allergies may be treated with antihistamines.

Second-generation antihistamines such as Allegra and Zyrtec may offer better relief than older-type antihistamines such as promethazine (older antihistamines tend to thicken post-nasal secretions). Intranasal antihistamines, such as azelastine, own a faster onset of action (15 minutes) and appear more effective than oral antihistamines although require more frequent istration. Other treatments include decongestants, cromolyn, and corticosteroid nasal sprays.

In the treatment of post nasal drip caused by nonallergic causes, oral second-generation antihistamines are not extremely effective.

However, the intranasal antihistamine azelastine is effective. Azelastine improves every rhinitis symptoms including nasal congestion, postnasal drip, sneezing and sleeping difficulty. The most common side effect is a metallic aftertaste; however, this is more likely at higher dosages and tends to dissipate with continued use.

Allegra Vs Zyrtec To Relieve Freezing Symptoms

Second-generation antihistamines (such as Allegra and Zyrtec) own limited effectiveness at relieving symptoms of freezing such as a runny nose and sneezing (only 45% of adults felt better after using them compared to 35% with placebo [a pretend pill]).

Effects were only noticeable if used within the first two days of a freezing, use of antihistamines made no difference thereafter.

Allegra Vs Zyrtec: istration

The antihistamine effects of Allegra and Zyrtec final for at least 24 hours, therefore, they are both given once daily. Fexofenadine, the athletic ingredient of Allegra works within two hours. Cetirizine, the athletic ingredient of Zyrtec works within one hour.

Allegra Vs Zyrtec: Side Effects, Interactions and Price

Side effects are generally mild with second-generation antihistamines and include a headache and rarely dry mouth, and nausea.

Zyrtec is times more likely than Allegra to cause sedation; however, Zyrtec is still much less sedating than older antihistamines such as promethazine.

Side effects are generally mild with second-generation antihistamines and include a headache and rarely dry mouth, and nausea. Every the second generation antihistamines currently on the market appear free from adverse cardiovascular effects. Few major interactions own been reported with either Allegra or Zyrtec; however, there is the possibility that side effects such as sedation, confusion, and mental alertness may be enhanced if given with other drugs with this side effect.

Grapefruit juice appears to decrease the rate and extent of absorption of fexofenadine (Allegra) by about 30%.

Cetirizine (Zyrtec) has no reported interactions with grapefruit or grapefruit products. More studies are needed to determine if there are any interactions between second generation antihistamines and herbal products and other types of food. Always speak with your doctor of pharmacist before using any drugs in combination.

Cost is similar for 30 Allegra and 30 Zyrtec tablets and both are available as generics.

Feeding cats a diet coated in a specially formulated egg powder product can neutralize the feline allergens that trigger symptoms in people, Purina scientists announced recently.

In a conversation with dvm, researchers explained that the major feline antigen present in cats' saliva is a protein called Fel d1, and while scientists don't know exactly what the protein does for the cat, they do know it's responsible for 95% of cat allergies in people-and that one in five people are allergic to cats.

Every cats, even those that are hairless, produce Fel d1, although levels vary from cat to cat and in the same cat over the course of a year.

Here's what happens: When a cat grooms, it transfers Fel d1 from its saliva and sebaceous glands to its fur. The antigen then spreads into the environment attached to shed hair and dander. It's known to be fairly “sticky,” Purina folks tell, clinging with a vengeance to blankets, carpet and curtains in the home and even making its way into public places.

When a sensitive person comes into contact with Fel d1, the allergen binds with IgE molecules in the immune system, triggering mast cell degranulation and an immune response-the distress of sneezing, itching, watery eyes and so on.

Cat owners who talk to their doctors about these symptoms often hear that the best remedy is to get rid of the cat; in fact, 18% of cats that finish up in shelters are relinquished because of allergies, Purina representatives tell. Other allergy-control options include antihistamines, immunotherapy, meticulous cleaning, confinement of the cat to a limited area or some combination of the above. The problem: None of these solutions are especially appealing or foolproof.

Enter this new study by Purina. In a decade-long research effort recently published in Immunity, Inflammation and Disease, scientists found that the IgY molecule present in egg yolk (an antibody passed from hens to their chicks) can block specific sites on the Fel d1 molecule, keeping it from binding with IgE and thereby neutralizing the allergen.

When cats were fed a diet coated with a specially formulated egg powder product containing IgY, 97% of cats showed decreased levels of athletic Fel d1 on their hair and dander compared with baseline. On average, there was a 47% reduction of athletic Fel d1 on cats' hair after three weeks of feeding the diet, with a range of 33% to 71% reduction.

Purina scientists report that there was no difference in health parameters between the control cats and the cats eating the special diet, which seems to indicate that the product is safe for cats to consume.

They also emphasize that the egg product does not suppress or destroy Fel d1-that protein may frolic an significant role in cats' physiology. Rather, the product neutralizes its allergenic effects, which means there's a greater chance that allergen levels in the environment will stay under the threshold that would trigger symptoms in people.

“These allergens own created a huge barrier to cat ownership and may limit the loving interactions between cat lovers and cats,” says immunologist Ebenezer Satyaraj, PhD, director of molecular nutrition at Purina and lead investigator on the research. “Our discovery has the potential to convert how people manage cat allergens.”

More results from the research will be shared by the Purina Institute, an organization that serves as the global voice of Purina's scientific communications, as they become available.

When youre rubbing itchy eyes and sneezing your way through anallergyflare-up, do you also feel muddled and fuzzy-headed sometimes?

Numerous allergy sufferers describe an experience known as brain fog — a hazy, tired feeling that makes it hard to concentrate.

What is this phenomenon and why does it happen?

According to allergist and immunologist Mark Aronica, MD, that disconnected feeling is fatigue, and it’s caused by the inflammation that results when your body tries to counteract your allergy symptoms.

“People with allergies experience inflammation,” he says.

“That inflammation leads to a congested nose, disrupted sleep patterns and not getting excellent rest.”

And, once the cycle starts, its sometimes self-perpetuating. You can discover it hard to go about your daily routines.

The more fatigued you are, the more difficulty you’ll own performing well in school or work. It can also negatively impact your quality of life if you’re too tired to do things you would normally do.

Whats really happening?

Your body produces whats called cytokines whenever youre exposed to an allergen, such as pollen, grass or mold, Dr.

Aronica says. (Contrary to favorite belief, the pollen in most flowers doesnt cause allergies, but floral scents can still cause problems for people with sensitive noses.)

Cytokines are are proteins that are part of your body’s immune response to foreign substances. You also produce them when fighting infections caused by bacteria, viruses and colds.

The cytokine release causes inflammation in your nose, leading to congestion and narrowed airways.

If you own allergies, allergen exposure leads to ongoing inflammation. And nasal congestion and disturbed sleep combine to give you that fuzzy-headed feeling.

“Chronic inflammation from allergies can lead to that foggy feeling,” he says.

“And, you’ll finish up not functioning well.”

Fighting the fog

If your allergies are acting up and you feel the fog rolling in, there are a few things you can do to assist stop the debilitating cycle of symptoms, inflammation and fatigue, Dr. Aronica says.

1. Limit your exposure.If you’re allergic to pollen or grasses, do your best to stay away from them. Stay indoors when theyre at their peak.Keep your windows closed if you own air conditioning.

If you do spend time exterior for longer periods, take a shower and change your clothes correct away when you come in.

If you’re allergic to dust or mold, hold up with dusting and cleaning to hold them out of your home as much as possible.

2. Take your medicine.Medication can assist curb your allergy symptoms. Oral antihistamines (medications that prevent you from responding to the histamines that cause inflammation) are readily available.

They’re a temporary solution, but they are often effective.

Over-the-counter and prescription nasal sprays can also assist combat your allergy symptoms, Dr. Aronica says.

3. Get allergy shots.This is the strongest form of treatment for allergy symptoms. Little injections of allergens under the skin can assist your body build up an immunity over time. The result is less frequent and less severe allergic rhinitis, Dr. Aronica says.

He adds that some allergy sufferers also discover relief with nasal lavage — a saline wash that cleans out the sinuses and nasal passages.

Numerous people ister this type of wash with aneti pot to clear out lingering allergy symptoms.

Dr. Aronica notes that other conditions besides allergies may cause fatigue and brain fog. If you own a sore throat, cough, fever or body aches,you could own a freezing or other illness and should take medications that will combat those symptoms.
