Contraindications for Immunotherapy

Allergies are not always clear cut and simple to understand. A person may assume that a certain food or substance is the cause of their symptoms and relate it to allergies, or they may not see the complete picture. We know allergy testing is extremely beneficial in allowing a provider to determine precisely what is or is not causing troublesome symptoms. Accurate diagnosis of the allergy, along with insights into any current medications that have failed to improve or control symptoms, avoidance measures taken, and impact on daily life enables your provider to determine the best treatment program which often includes immunotherapy.

When a provider is considering allergy testing and immunotherapy, it is important to take into consideration potential contraindications that may warrant a different approach including potentially refraining to utilize United Allergy protocol in a particular patient. A contraindication in our instance is a particular condition which makes allergy testing or allergen immunotherapy potentially inadvisable. A contraindication may be absolute meaning that is any situation that this condition is present it is definitely not advised allergy testing or immunotherapy is utilized. The majority of contraindications applicable to allergy testing and immunotherapy, however, are relative. A relative contraindication means a certain condition can drive concern and could increase risks making it possibly inadvisable. Risk vs benefit assessment needs to take place.

Patients that present with one or more of the following contraindications should be screened thoroughly by the provider and the benefits for testing and treating patients with immunotherapy must be weighed against the risks associated. This important assessment and determination on how to proceed will always rest with the ordering provider directly supervising the care of the patient.

  • Beta Blockers: We highly recommend providers that have patients on beta-blockers consider switching them to another medication if appropriate prior to initiating immunotherapy. A beta-blocker may mask cardiac signs or symptoms related to anaphylaxis. Also, if a patient has an adverse event, they may not respond to the epinephrine needed to counteract the life-threatening reaction. There is currently limited data available to support holding beta blockers for a short time period such as 24 hours prior to an allergy test or immunotherapy dose to increase a patient’s safety.
  • ACE Inhibitors: ACE inhibitors have been another cardiac medication thought to pose a risk if utilized with immunotherapy. ACE Inhibitors are considered due to their mechanism of action although whether they pose a significant risk as always been a major topic in academia. During an adverse reaction, it is thought that an ACE inhibitor can block the endogenous compensatory response manifested by the increased secretion of angiotensin-converting enzymes and prevent the destruction of kinins produced during the anaphylactic episode. The evidence regarding a true increased risk has not been clearly proven with environmental allergen immunotherapy and so is not currently included on our list of potential contraindications. Currently, data supports increased risk in venom allergen immunotherapy which is not offered under UAS protocol.
  • Cardiac conditions: Patients with historic and current cardiac issues such as congestive heart failure, myocardial infarction, labile arrhythmias, uncontrolled hypertension, or other significant cardiac problems could be negatively challenged clinically if they experience anaphylaxis due to allergy testing or immunotherapy. Furthermore, many of these patients may not successfully tolerate the consequences of epinephrine injections if required to treat anaphylaxis.
  • Previous history of anaphylaxis to aero allergens: Patients that have a history of previous reactions are much more likely to have a repeat reaction, oftentimes more severe than the initial reaction.
  • Pregnancy: Pregnant patients must remain at the same concentration level of immunotherapy throughout the pregnancy and should not increase the dosage volume or concentration. This is because repeating the same positively tolerated dose, protects the expectant mother and developing fetus from potential harmful effects of epinephrine should a significant systemic reaction occur. It is beneficial for patients that become pregnant or plan to become pregnant at prior to testing, or at low dosage/concentration, delay allergy testing and immunotherapy until the pregnancy has concluded.
  • HIV positive/ AIDS patients: AIDS or AIDS associated disorders are absolute contraindications to immunotherapy, however HIV+ status only is not always contraindicated according to literature. UAS currently recommends providers with patients with a positive HIV + status consider seeking an alternative protocol with an opportunity for closer and more consistent in office monitoring. However, despite this advisement, it is important to share there is no current absolute contraindication for a patient with a positive HIV status to begin allergen immunotherapy. There also are no large, controlled studies that can provide validity to the risks or to the benefits of allergen immunotherapy in HIV positive patients. There have been citations in recent literature to demonstrate both a negative response to initiation of immunotherapy (in which T-cell proliferation and RNA viral load increase occurred) and a positive response (a 3.5-year course of immunotherapy reduced symptoms and medication use, as well as provided well controlled symptoms 3 years port IT, without significant impact to HIV disease).  Each patient must be closely assessed on an individual basis.
  • Immunocompromised patients/ chemotherapy patients (including AIDS patients as mentioned above): Immunocompromised patients have not been shown in the literature to receive benefit from immunotherapy. Immunotherapy works by changing the T-cell repertoire. In immunocompromised patients T-cells are often altered. Thus, patients with an immunocompromised state are not recommended as candidates for immunotherapy.
  • Patients with autoimmune diseases or utilizing immunosuppressant medications: As quoted from the AAAAI “Although concern about the safety of allergen immunotherapy in patients with autoimmune disorders has been raised in the past, there is no substantive evidence that such treatment is harmful in patients with these diseases.” Due to the variation in these different disease states and individual patient situations, it is recommended the benefits and risks are assessed on an individual basis. When a patient is utilizing an immunosuppressant medication there are theoretical concerns that immunotherapy's benefit could be lessened, however there is no overarching body of evidence in literature that provides clear evidence of this regard. The best guidance I can provide for the ordering provider is to have full transparency with the patient regarding the theoretical concern of decreased efficacy of IT and considering holding immunotherapy during active exacerbations of autoimmune diseases.
  • Uncontrolled asthma/severe asthma/severe COPD: The group of patients with the highest risk of severe reactions to allergy testing or allergen immunotherapy are asthmatics, particularly those that have uncontrolled or severe asthma. This can apply to anyone with impairment, obstruction, or restriction of their airways. To protect against a negative outcome of a severe systemic reaction it is strongly recommended providers do not test, initiate immunotherapy, or continue immunotherapy while a patient is in a compromised respiratory state.
  • Eosinophilic Esophagitis (EoE) or Gastroenteritis: This is a concern that applies to sublingual immunotherapy ONLY and does not pertain to subcutaneous immunotherapy.  In sublingual immunotherapy, the allergen is swallowed and has direct contact with the esophagus. Swallowed food, and an allergic response to the food or allergen is presumed to be important in the development or worsening of EoE. Therefore, it is thought that exposure of an aeroallergen with the esophagus can produce the same effects. Package inserts for the FDA approved SLIT tablets indicate that eosinophilic esophagitis is a contraindication for use.
  • Inability to communicate: Patients undergoing allergy testing or allergen immunotherapy need to possess the ability to both mentally and physically participate in their diagnostic and/or treatment plan. The ability to clearly express and communicate active symptoms is crucial should an adverse reaction occur. Patients also need to possess the mental ability to understand the procedure or treatment ordered for them, be cooperative during the process, and understand the importance of their compliance.

United Allergy Services believes in appropriate patient selection (taking into consideration relative and absolute contraindications), doses building in a low, slow deliberate manner, and treatment in compliance with the relevant standards of practice guidelines. The proven safety results and efficacy of the self-administered subcutaneous immunotherapy protocol developed by United Allergy Services is based on a pre-selection of low-risk patients.  If there are additional questions or any additional information requested, please contact the Clinical Support Team. We are here to support providers and provide guidance as they provide excellent allergy care to their patients.

2022 - New Year, New You!

Happy New Year, and welcome 2022! The start of a new year arrives for many with guilt-laden resolutions to improve things like personal health goals. Resolutions to improve health can seem overwhelming and cause anxiety if they are unrealistic in the end goal or timeframe. Allergy and asthma sufferers do not have to overhaul an entire health plan to see some solid results. A few simple tweaks could make a big difference in easing sniffling, sneezing, and wheezing.

⦁ Adding Exercise – Is it even a New Year’s resolution if it doesn’t involve adding exercise or physical activity – and it’s an especially good goal for those with asthma! It is a common misconception, and one that can be detrimental to overall health, that those with asthma should not exercise. It is true that when asthmatics exercise in certain places or conditions, such as  in cold weather, it can make asthma symptoms worse, so avoid exercising outside if it’s cold and windy (or hot and humid). Air pollution – both indoor and outdoor – as well as high pollen counts, can also cause symptoms during exercise. Consider sports that typically require shorter bursts of exertion or activity like volleyball, gymnastics, baseball, wrestling, golf, and swimming. Using an inhaler before exercising and as needed during exercise can further help. If asthma limits your ability to exercise, talk to your provider to discuss a possible adjustment to your asthma medication routine, or better control of your allergies through testing and allergen immunotherapy.

⦁ Decrease stress – Numerous studies have shown that stress can cause negative health effects, including increased or worse symptoms for allergy and asthma sufferers. Consider downloading a meditation or relaxation app to use at night before bed. Soothing music can also be beneficial, as can doing activities you enjoy that lift your spirit.

⦁ Stop smoking or ban it from your surroundings – Quitting smoking and making your house a smoke-free environment could easily be the single best resolution to make as an asthma and allergy sufferer. This resolution should be on the top of your list. Direct smoke and secondhand smoke is extremely damaging and harmful to many parts of the body, but particularly the lungs. Studies have shown children with asthma who are exposed to secondhand smoke at home have nearly double the risk of being hospitalized than children with asthma who aren’t exposed. If you or your kids have asthma you should also try to avoid fireplace fires and campfires.

⦁ Protect yourself - It's important to do all you can to protect yourself against respiratory viruses like influenza, RSV, and COVID-19 because people with asthma and allergies can be at an increased risk for severe illness. For viruses like the flu and COVID-19, get vaccinated, or get a booster shot, wear a mask when appropriate and social distance.

⦁ Watch what you eat – but wait, this has nothing to do with dreaded dieting! -  For those with food allergies, remain diligent in avoiding the foods you are allergic to. This year, double down on making sure those you love, especially teens or college students, are being vigilant. Older kids sometimes believe not mentioning food allergies helps them not stick out among their peers. Encourage them to courageously educate their friends and enlist their help in the battle to stay allergen-free. Help them take control of their food allergies by urging them to be aware of what’s on the menu wherever they eat. Also, resolve to make sure epinephrine auto injectors are current and up to date, and that two sperate doses or injections are always available to be utilized within 60 seconds of need.

⦁ Proactively see your provider – Each year people wait to discuss their allergies and asthma with their provider and be evaluated when pollen season and allergy symptoms are at their worst. Avoid reaching that level of suffering, the allergy season rush, and the inability to be allergy tested due to need for allergy medications by proactively seeing your provider now. Your provider can help you determine what is causing symptoms and show you how to avoid triggers.

Eczema and Atopic Dermatitis

We have made it to the highly anticipated holiday season! We ate more than our share of turkey, taken down the last of the fall décor, have started trimming the tree, and are double down on the holiday gift lists. With winter weather upon us or in the near future, and personal care products a favorite stocking stuffer, this is a perfect opportunity to think about proper skin care, especially if eczema or atopic dermatitis is present.

It is common for patients and even healthcare providers to use the terms ‘eczema’ and ‘atopic dermatitis’ interchangeably. All atopic dermatitis is a form of eczema, however not all eczema is atopic dermatitis. Atopic dermatitis is the most common form of eczema and typically begins in childhood. Someone suffering from atopic dermatitis typically has dry, itchy skin, as well as potential rashes that range from red/purple to brown/gray. The skin becomes so dry, itchy, and inflamed due to the immune systems hyperactivity, and loss of or lack of a protective protein called filaggrin that allow our skin to produce and maintain a strong skin barrier. Without a strong skin barrier, it is easy for moisture to quickly escape and bacteria carried by fingernails scratching the skin’s surface to get in.

Atopic dermatitis can be triggered by allergen exposure, stress, infection, or commonly weather changes. Atopic dermatitis can unfortunately worsen drastically in the winter, with this month being the start of the season in the US. The cold, dry air outside as well as the dry indoor heat cause the moisture to escape from the skins surface leading to dry skin. Issues with dry skin are further compounded by the tendency to layer up clothing and blankets, or taking lengthy and hot baths or showers.

If the itching keeps on giving this holiday and winter season, here are some helpful hints on how to help the skin survive and get some much-needed relief:

  • Dress in soft, breathable clothing and avoid itchy fabrics like wool that can further irritate the skin.
  • Despite the persistent itch, try not to scratch or rub the skin. This will cause additional damage and irritation as well as cause more heat on the surface of the skin which innately leads to more intense itching. By refusing to scratch, the itching cycle is broken and the skin is protected from virus and bacteria carried by fingernails.
  • For relentless itching sensations, apply cool, damp cloths to affected areas to cool the skin down. Also useful are cold compresses, ice packs, or even that bag of frozen peas in the back of the freezer. Just make sure to always place a towel or barrier between very cold or frozen items and bare skin.
  • Although hot showers and baths go hand in hand with winter weather, aim for lukewarm water bathing lasting for no more than 10 minutes.
  • When bathing, skip the harsh washcloths and loofahs. Instead use your hands to lather up with a good cleanser. (A cleanser is different than soap or body washes. Soaps and body washes typically contain sodium lauryl sulfate which is a skin irritant, and are not as moisturizing or hydrating as a cleanser)
  • Make sure cleansers, moisturizers, detergents, and skin hygiene products are fragrance free and dye free. (Look for the National Eczema Association Seal of Acceptance on products to guarantee they are free of fragrance, dyes and other common allergens.)
  • When done bathing, pat the skin dry rather than harshly rubbing.
  • Replace moisture in the skin by applying a moisturizer immediately after taking a bath or shower. Try to aim for moisturizing to occur within the first 3 minutes.
  • Moisturizers can be classified as an ointment, cream, or lotion based on the amount of oil and water they contain. The more oil in a moisturizer, the better it usually is at providing relief and even treating atopic dermatitis. Ointments have the highest oil content and are the best line of defense for atopic dermatitis.
  • Try using a humidifier.  Make sure to change the water in the humidifier and clean the machine every three days. Consider using distilled or demineralized water.

The National Eczema Association is a great resource for learning more about eczema, atopic dermatitis, causes, symptoms, and treatment options. There is a wealth of information on their website: https://nationaleczema.org/


Dust Mite Allergy

Halloween may be over, but there are certain creepy creatures that diligently remain year-round and commonly trigger allergy and asthma symptoms. Dust mites are eight-legged relatives ticks and spiders, have no eyes, have translucent bodies, and are microscopic, or too small to see with the unaided eye. These tiny creatures love to make their home on human and pet bedding, mattresses, carpets, curtains, toys and upholstered furniture. They love to choose these locations for their homes because of the plentiful food supply. Dust mites regularly feed on the dead flakes of skin that people and pets shed daily and gain their water from moisture found in their environment (think humidity and sweat!). They live somewhere between 60 and 100 days.

Dust mites are well adapted, and currently inhabit every continent except Antarctica. There are two main species of dust mites, the American house dust mite (Dermatophagoides farinae) and the European House dust mite (Dermatophagoides pteronyssinus). Providers utilizing United Allergy Services for their patients’ allergy needs can safely test and treat their patients to both species of mite. Dust mites, as opposed to bed bugs or other parasites, will not and cannot bite you. Dust mites are extremely lightweight and cannot be felt crawling on the skin. They can cause allergic or asthma symptoms in some when those sensitive to them inhale the microscopic fecal matter and shed skins of the mite.

As with any allergen, the goal is to first identify the allergen as troublesome to the individual person and develop a treatment plan. A treatment plan should always include how to reduce the exposures to the offending allergen. However, if your home has humans or pets living in it, there are dust mites present, and it is impossible to avoid them completely. There are several things that can help diminish their food supply and create less of a welcoming environment. The best approach with dust mites is trying to convince them that their current environment will be too much work to maintain their existence. Trying to kill them is almost impossible, there is no spray or pesticide currently labeled in the United States for the destruction of dust mites, and dead dust mites still shed the problem causing protein that triggers allergy and asthma symptoms.

Hard surfaces such as vinyl, wood, or tile, and other hard surface blinds instead of curtains or draperies are helpful in decreasing the dust mite colonization in a home. It is also beneficial to select leather furniture as opposed to upholstered and remove things like books, lamps, knick-knacks, and dust catching items from a room. These steps, although beneficial to a home, can be challenging if home renovations are not in the budget. And who plans to live in a home without any type of lamp, picture frames, or other décor? There are other steps to reduce the dust mite colonization of a home.

First and foremost, a regular and thorough cleaning of the surfaces and regions that dust mites are most likely to dwell is an easy front-line approach to sending dust mites searching for another place to call home. It is especially important to focus on where someone will sleep as this is when a person can spend upwards of 8 hours a day breathing in potential allergens. Cleaning and washing all bedding such as sheets, blankets, and pillowcases in a hot, sanitary cycle is recommended once weekly. Sleeping quarters can further be protected from dust mites by using special covers and encasements to keep out these unwanted visitors. An encasement should be placed on each mattress and sleeping pillow in the home. As well as cleaning and covering areas in which sleeping occurs, it can be beneficial to keep pets and copious amounts of dust collecting stuffed toys out of sleeping areas and off beds as well.

Dust mite body casings are lightweight and can easily become airborne and travel through the air. Ceiling fan blades can harbor dust and dust mites and allow dust to become easily airborne. It is imperative to regularly dust fans, especially before turning on.  Air quality can also be improved by using a high-energy particulate absorption (HEPA) air purifiers on the air conditioning and heating units, as well as the vacuum to remove many allergens, especially dust mites, from the air. A dehumidifier can also be helpful as it helps to create a less favorable environment for the dust mites to survive. Remember, dust mites get their water supply from the humidity in the air as well as human and pet moisture, aka sweat, left behind! Just make sure to regularly clean the dehumidifier unit to prevent mold growth. And finally, wearing a mask can be beneficial to allergy and asthma sufferers when cleaning the home, removing bedding or drapery for washing, or taking out and putting away things from storage spaces like holiday decorations.


Respiratory Care Week, October 24-30

As we settle into this final week of October and prepare for some frightful fun at the end of the week, let’s all take a big deep breath in before the end of the year holiday season is upon us! Speaking of that big dep breath, October is Healthy Lung Month and this week, October 24-30 is Respiratory Care Week. This week we focus on the importance of protecting our lungs against infections like bronchitis, allergens such as mold, air pollution and smoking because if we take care of our lungs, our lungs will take care of us.

One of the more impactful allergens on the lungs specifically, is mold. Mold is a type of fungi, and the seeds or spores of the mold travel easily through the air to reproduce and grow. There are many different types of molds, and some spores thrive in dry, windy weather while other spores need damp, humid environments. Although there are many different types of molds, not all mold is responsible for allergic reactions. The most common allergy-causing molds include Alternaria, Aspergillus, Cladosporium and Penicillium.

Mold is unfortunately everywhere, indoors, and outdoors, and is a year-round allergen, although is typically at its highest from July through October or November. Some of the most favorable places for mold growth are on rotting logs or plants, piles of fallen leaves, compost piles, and on grasses or grains. Mold also tends to grow in cool, damp environments indoors such as basements, kitchens, and bathrooms. Tracking symptoms along with exactly where someone has been, can be extremely helpful to a provider trying to determine if mold is an allergen for their patient and the culprit for the troublesome symptoms the patient might be experiencing. Everyone breathes in mold spores on a regular basis, however, those that have an allergy to mold can experience itchy nose, mouth and lips, sneezing, itchy, watery eyes, and nasal symptoms. Those allergic to mold with underlying allergic asthma are especially susceptible to increased wheezing, coughing, chest tightness, or shortness of breath.

With molds living indoors, outdoors, and year-round it might seem overwhelming to figure out how to avoid this troublesome allergen. Similar to pollen counts, mold spore levels in the air are regularly tracked and reported so it is important to check the allergen forecasts and try to limit time outdoors when counts are high. Planning for indoor exposures can be a bit more challenging, however, some spots like greenhouses, farms, flower shops, construction sites, and antique shops are bound to have higher mold spore counts. Plan to take additional allergy medication, avoid during symptom exacerbations or bring a mask to help lower exposures.

Large fields of grains and grasses, and piles of dead, damp leaves are prime places for mold. Avoiding those places is beneficial, and if planning for the young or young at heart to jump in their fall leaf piles, try to plan for a day with low outdoor mold counts if possible. It is important to try to immediately shower after outdoor activities like mowing, or jumping in leaves, especially before crawling into bed. This will help to wash away any allergens that have adhered themselves to your skin or hair and are hoping to enjoy your comfortable accommodations right alongside you. This is especially important before allowing them to have access to your pillow or sheets and being in the immediate space and air you breath in all night.

Finally, and possibly the most important, let’s focus on how to minimize mold existence and exposure in the home environment. As discussed previously, indoor mold tends to prefer damp, humid environments, and areas with high levels of moisture in the air. Consider using a dehumidifier and air conditioners/heating units fitted with high-efficiency particulate air (HEPA) filters. It is best to try to keep humidity below 60%, ideally between 35% and 50%, and that can be easily tracked with a humidity meter available at a low cost at most hardware stores. Mold can thrive in warm, damp bathrooms and humid kitchens. If the kitchen or bathroom has an exhaust fan, use it, especially when taking a shower or bath. This will help to further reduce humidity in these rooms.

Clean surfaces do not provide a conducive environment for mold spore attachment and reproduction however soap scum in the bathroom or grease in the kitchen do provide an inviting area for mold growth. Aside from regular cleaning, it helps to closely monitor counters, and more importantly refrigerators, drip pans, door seals, showers/baths, AC drain lines, dryer vents and garbage pails. If the kitchen and bathroom have proven to be difficult areas to control mold growth, consider removing carpeting from kitchens, bathrooms, and basements, and replacing with linoleum or concrete flooring to inhibit floor mold growth as these surfaces do not hold moisture. Finally store things like old schoolwork, projects, paper, and clothing in plastic, airtight containers as opposed to plastic bags.


football, food, and fall allergies

Football, Food, and Fall Allergies

Fall has arrived and so have shorter days, cooler weather, and football season! Unfortunately for some, football, food and fall allergies go hand in hand. This is especially true in the southern and western regions of the US where some weed allergens peak in the fall. The idea of sneezing and wheezing with itchy, watery eyes while watching a game or practice can be dreadful. Perhaps more concerning is visiting major sports venues if you or a loved one have food allergies.

Outdoor Allergies

It is common to check the weather forecast to plan for warm or cool temperatures when attending sporting events. . A good habit may be to also check the local pollen counts in the area. Keep in mind that peak pollen times are typically in the first half of the day (specifically 5am 10am). Attending practices or games midday, in the afternoon, or in the evening may help to reduce exposures.

Avoidance for Fall Allergies

If you have a future MVP of your own, packing some wet wipes could be helpful. Wiping down their hands, face and neck can combat those distracting allergy symptoms when out on the field. Also, verify any allergy medication they take will not make them drowsy during their practice or game. Non-sedating medication options or allergen immunotherapy may be worth discussing with their provider.

After practices or games, changing out of the clothing worn while participating or spectating can help alleviate allergy symptoms. Also helpful is an immediate shower, particularly before crawling into bed. Showering will help to wash away any allergens that have adhered themselves to your skin or hair. This is especially important to keep them out of the immediate space and air you breath in all night.

Food Allergies

If food allergies are a concern, planning ahead can alleviate a lot of anxiety and allow for a smooth trip. Always make sure to carry a minimum of two epinephrine auto injectors if one is prescribed to you or a loved one. Make sure the epinephrine autoinjector is carried in a way it can be accessed and administered within 60 seconds of a need arising. The Food Allergy Research and Education (FARE) organization recommends “to reach out directly to the venue to learn more about their efforts” in regard to additional steps they may be taking to ensure your family’s safety at the game.

Food Allergy TipsFootball and Food Allergies

Some suggested topics to cover when you contact the venues are:

  • Availability of allergy friendly games, sections, or suites
  • Is power washing utilized for seating, and traffic pathways at the stadium?
  • Are ingredient lists available upon request at the concessions?
  • Policy for bringing in safe meals and snacks
  • Locations for emergency responders

Planning and communication make it possible to avoid fall allergies and enjoy football season. Communicate with family, friends, coaches, players, and venues, and create a plan that is right for your family. However, missing out on football season does not have to be part of that plan. If you or your loved ones are not quite sure if allergies are playing a roll, or if the allergy medication is just is not cutting it, consider contacting your provider and discussing allergy testing and starting allergen immunotherapy.

Ragweed and Fall Pollen Allergies

Back to school season is here! Shorter days, crisp, cool evenings, and beautiful fall foliage are on the horizon. This time also marks the onset of weed pollination and the resurgence of allergy symptoms that may have taken a vacation in the hot, dry July heat. The meteorological calendar says fall begins September 22nd, but weed pollen, the main culprit of the sniffles and sneezes during fall allergy season, is already here!

Pollen Offenders

Towards the close of summer, weeds start to pollinate. Weeds grow all summer, but their pollen is usually not released until later in the growing season. This can vary year to year but typically starts mid to late August.  Ragweed, cocklebur, lamb’s quarters, pigweed, dock sorrel, English plantain, and sagebrush can all cause fall allergy symptoms and are widely spread across the U.S.

Specifically ragweed pollen is the predominate culprit of allergy symptoms from August through October, peaking on average in mid-September. Ragweed is one of the major drivers of allergy symptoms and releases huge amounts of pollen each and every day. The pollen produced by ragweed is small and light. It is released in large quantities into the air and carried for miles by the wind. Nasal congestion, runny nose, and itchy eyes are typically caused by wind-blown pollen which is easily spread for miles and miles.

Other Pollen Types

Goldenrod, which blooms at the same time that ragweed does, is instead insect-pollinated and therefore is not a significant allergen for most individuals. Insect carried pollen is produced by plants that have bright and attractive flowers. This kind of pollen is typically large and heavy, sticks to insects, and is transported during flight fertilizing other plants. These bright flowers are commonly thought to be allergy offenders, however because they do not release much pollen into the air they are not as likely the culprit of allergy symptoms.

Ragweed and Fall Pollen Allergies
Ragweed and Fall Pollen Allergies

Manage Symptoms

Checking local pollen counts is helpful to anticipate the level of exposure on any given day. Pollen counts are determined by collecting pollen on special rods. The pollen is then counted under a microscope and calculated in grains per cubic meter of air. Pollen counts tend to be the highest early in the day, or often when the wind picks up just before a large rainstorm. If you like dancing in the fall rain, or jumping in rain puddles, however, you are in luck. During a rainstorm and immediately following, pollen becomes still and dormant because the rain makes it damp and heavy. As the air becomes warmer and drier following the storm, however, the pollen count will rise again.

Pollen Avoidance

Those with weed pollen allergies should try to avoid heavily dense wooded areas or those with brush and shrubbery. These areas should be especially avoided in late August when pollen is the most dense and abundant. Pollen counts are never zero, nor will an allergy sufferer truly be able to avoid weed pollen in the late summer and early fall. However, contact may be lessened by taking simple steps to avoid pollen overload:

  • Utilizing the air conditioner or heater
  • Keeping the windows and doors at home and in the car closed
  • Utilizing the dryer rather than the fresh breeze to dry clothing
  • Changing clothes after coming in from being outdoors
  • Shower prior to getting into bed or laying on upholstered furniture

These easy steps will help to decrease pollen exposures. Also, one benefit COVID-19 may bring allergy sufferers, is that wearing of some masks will help to minimize the amount of pollen reaching the nasal passages if being worn in outdoor settings.

Get Tested

If someone is unsure whether weed pollen is a trigger for their back-to-school nasal congestion, runny nose, post nasal drip, sneezing, and itchy watery eyes, seeing their provider for an allergy test may provide the clarity they are looking for!

Back to School Action Plan for Allergies and Asthma

Back to School Action Plan for Allergies and Asthma

As the final days of summer break come to a close, families everywhere are preparing for children to return to school. Whether this is the first year a child is heading to school or the last, it is an exciting time for both children and parents. It can, however, also be a time of anxiety for a parent worried about a child’s asthma or allergy conditions. Below are some ways to prepare and communicate these concerns, and  back to school excitement.

Make a Plan

Schedule an appointment with your child’s healthcare provider in the weeks leading up to the first day of school. During this appointment, discuss overall heath as well as specifics regarding allergies, food allergies, or asthma. This is also a great opportunity to request that the healthcare provider refill any asthma or allergy medications. The provider can complete medication permission forms required by the school nurse during your visit. It is important the school nurse can quickly and easily confirm the medication you provide is:

  • non-expired
  • prescribed for your child
  • has clear directions on when, how, and how much to take

This is also the time to request your provider complete any additional forms required by the school. Examples are asthma action plans, anaphylaxis action plans, and food allergy alert plans with avoidance and substitution information. If your child is in their first year or is entering a new school, it is important to contact the school nurse directly. Also, if your child has complex requirements or action plans, you should visit with the school nurse yearly about their daily requirements. The nurse can discuss accommodation options available for children at the school. Other important policies to discuss include asthma inhalers, epinephrine auto injectors, classroom parties, field trips, and cafeteria rules.

Classroom Action

Back to School with Allergies and Asthma
Back to School with Allergies and Asthma

The classroom can be a source of exposure for children with allergies to dust mites, mold, and animal dander. Communicate with your child’s teacher about allergy triggers for their symptoms and what common symptoms to look out for. Don’t forget to ask if the classroom will have a resident pet. If so, what type of animal and any requirements that the pet come home with your child may be important. It is also important to understand if the school has air conditioning or if windows are typically opened on nicer days. If windows must be opened, then you can prepare your child accordingly with additional symptom control medication.

During your initial meeting with the teacher, you can begin setting appropriate expectations. Discuss things such as asthma action plans and any potential limitations for recess or physical education. Also, anaphylaxis action plans for food or stinging insects and any food avoidance requirements should be covered. You will feel confident knowing both the school nurse and teacher are fully informed of your child’s needs. The school nurse and teacher should have a consistent plan for where inhalers and epinephrine auto injectors are stored. Also confirm that there is a plan for administration of medication in a time of need. It is a good idea to ask about substitutes or classroom aides/parent volunteers confirm they are made aware of your child’s needs.

When to Stay Home

During a regular year it is often a challenge to decide when it is or is not appropriate to send a child to school with cold-like symptoms. That can be even more complex for a parent if your child has allergies or asthma. In this unique time when COVID-19 is still a major focus, another layer of complexity is added.

For children with asthma, it is safe to attend school with mild wheezing that occurs infrequently and is quickly resolving with the use of albuterol. However, it is appropriate to keep your child home from school if:

  • they experience difficulty sleeping due to respiratory symptoms
  • require albuterol every 4 hours to relieve them of things like wheezing, shortness of breath, or chest tightness
  • have respiratory symptoms that are failing to resolve with albuterol use

Make sure to always inform the school nurse and the child’s teacher of any recent asthma exacerbations and how it was treated. Communicate any continued treatment if applicable.

If your child has an allergic reaction, make sure to inform the nurse. Also update the nurse on the allergen trigger if known, how the reaction was treated, and any ongoing treatment.

Wishing all the children a safe, healthy, and prosperous new school year!

Summer allergy avoidance tips

Summer Allergy Travel Tips

School is out, summer is in full swing, and it is prime time for summer vacations and traveling. Summer travel with environmental allergies, asthma, or food allergies may make planning a vacation seem like a daunting task. Not to worry! We can show how to keep summer allergy issues at bay during your staycation, beach trip or wine tour of your dreams.

Summer can be an ideal time to travel. The hot summer months can actually provide relief to some, like those with tree pollen allergies. Unfortunately for others, summer comes with its own allergy triggers. While tree pollen counts tend to be lower, the summer heat pushes grass and mold pollen to be higher. Ragweed begins to appear in the late summer and early fall months to kick off fall allergies. Pollen is not the only trigger you can expect; more stinging insects and hotter temperatures in summer months can complicate matters for asthma sufferers.

Summer Allergy Location Tips

Location is everything! One consideration is that pollen counts tend to be lower on the coast, so beaches may be a good option. The desert, or alternatively snowy mountain tops, can also be ideal for pollen, although maybe not for summer travel. Does your vacation involve hiking or mountain climbing? Dust mites do not prefer elevations above 2,500 feet, so that may be a great choice as well. Wherever you decide to go check the allergen forecasts for that area. You should also check current pollen counts each day there. If high pollen counts are in the forecast, consider planning inside activities during your trip.

Checking pollen counts may not be the only forecast to make sure to monitor. As the temperatures rise, you can expect the humidity to rise as well. Many who suffer from asthma can find their condition aggravated by the high temperatures and humid climate. When planning your time outside during the summer, check the air quality for low humidity and low ozone days. You can also avoid triggers by planning around the heat of the day when possible.

Packing for Vacation

Although your favorite swimsuit may be more fun, allergy control measures should equally be at the highest priority. Staying compliant to your recommended treatment protocol in the days before you leave is crucial. These measures will support well-maintained symptoms while traveling, and for the duration of the trip.

  • Make sure to pack allergy medication and immunotherapy in a carry-on bag if traveling by plane.
    • Try to keep medications in original packaging and pack all medication and allergen immunotherapy in a separate, clear bag.
    • Any liquid or gel medications or immunotherapy will need to individually be 3-4 ounces or smaller. Consider purchasing travel sizes if standard sizes do not meet this requirement.
  • Pack 1-2 days of additional medication or immunotherapy than what will be needed in case of delay when traveling.
  • It may be beneficial to set a reoccurring alarm on a phone before leaving. Normal routines may change with travel and vacation plans.
  • Finally, are you traveling out of the country? If you are traveling to a non-English speaking location, bring a list of your allergies in the native language. You may also learn to say or write  “I’m allergic to _____.” in the local language.

Additionally, do not forget to pack any hypoallergenic hygiene products that you regularly use. Examples might be sunscreen, after sun cream, lotions, ointments, body wash, or laundry detergent. When searching for accommodations, remember that more and more hotels offer items like mattress and pillow covers or hypoallergenic linens so you may not have to pack your own. It may also be helpful to ask about smoke free rooms, away from humid, mold friendly pool areas if possible. If pet dander is a concern, take note of whether the location is “pet friendly”.

Summer Allergy Avoidance Tips

Air in enclosed spaces such as planes and trains can sometimes be extremely dry.  Consider investing in nasal saline spray or washes, as well as portable humidifier. A humidifier will likely also be beneficial if staying in a hotel for more than a night or two. Staying well hydrated with water and non-caffeinated beverages will also greatly help you combat drying out. If traveling by car, considering utilizing the heat or air conditioning and keeping windows closed. Also, turning on the heat or air 10 minutes before departure can help clear vents of any residual allergen particles.

While enjoying your destination, remember that peak pollen times are typically early in the day (specifically 5am 10am). Scheduling desired outdoor activities for later in the day or just before dusk may help to reduce exposures. Similarly to when you are home, a daily shower is helpful for allergen avoidance. Showering before bed will help to wash away allergens that have adhered themselves to your skin or hair. This is especially important to maintain so that your pillow, sheets, and the immediate space you breathe in all night is allergen free.

Insect Allergies

Another aspect of the summer allergy concerns may be insects. If stinging insect allergies are present planning ahead can alleviate a lot of anxiety and allow for a smooth trip. Always make sure to carry a minimum of two epinephrine auto injectors if it has been prescribed to you or a loved one. Make sure the epinephrine autoinjector is carried in a way it can be accessed and administered within 60 seconds of a need arising.

If you or a loved one does have life threatening allergies, it is a good idea to check with your health insurance and ensure you know where to seek medical care should the need arise while you are out of town. You may also consider carrying an allergy identification card. It can be helpful to keep a card in your wallet listing your allergies, and also emergency contact information and your healthcare provider information. This can be especially important for children who may be summer camps or staying overnight with friends or family.

Food Allergies

If food allergies are present, packing your own meals or snacks may make traveling easier. Preparing food yourself is always the safest option. Alternatively, research the local dining hot spots you wish to visit in advance of leaving for your trip. This allows you to identify safe selections from the menu or you can call to request proper menu accommodations. You may still consider packing your own snacks if you have food allergies. While it may be possible to plan meals around food allergies, snacks often present more of a challenge. Pack allergy friendly snacks, especially if lengthy plane rides are involved.

Grass Pollen Allergy: Making the Most of Summer

Summer is finally here! Longer days, days spent by the beach or the pool, and late nights catching fireflies are on the horizon. Allergies are usually associated with the spring or fall because pollen is most active during these times. However, summer allergies, especially to grass, are also common. This grass pollen allergy can cause some of the same troublesome symptoms as in other seasons.

Allergy Season

Grass begins to pollinate in the late spring, typically April or May in the northern part of the country. The pollination period in the north will then typically continue through June or July. However, in southern regions, grasses may pollinate throughout many seasons and could trigger symptoms throughout the year. These pollination time periods are when those who suffer from a grass pollen allergy

notice their symptoms at their worst.

Types of Grass Pollen

There are hundreds of different kinds of grasses throughout the United States. Fortunately, not all of them are the source of summer sneezing, congestion, and itchy eyes. Some grass pollen types are small, light, dry and can travel for hundreds of miles by the wind. One group of grasses, referred to as the northern pasture grasses, cause more allergy problems than any others. These grasses include:

  • common timothy grass
  • sweet vernal grass
  • orchard grass
  • perennial rye grass
  • Kentucky bluegrass

Another type of grass, bermuda, is a southern grass and is responsible for many troubling summer grass allergy symptoms. Johnson grass is another main culprit for grass pollen misery.

Options for Homeowners

While common Bermuda grass usually triggers allergies, some hybridized versions produce little to no pollen. One common type of hybrid Bermuda grass referred to as the "Princess 77" variety is available for homeowners. Other good hybrid Bermuda grass varieties include "Tifway" and "Santa Ana". Buffalo grass may be a good warmer climate option. This warm-season grass survives droughts and requires little supplemental watering, making it ideal for areas with watering restrictions. Types like the "UC Verde" or "609" produces only female plants, eliminating the problems of flowering and producing pollen. Although less commonly found, this is ideal for grass pollen sufferers.

Measuring Grass Pollen Counts

Those that suffer from a grass pollen allergy can benefit from checking their local pollen counts regularly. Pollen counts are determined collecting pollen on special rods. The pollen is then counted under a microscope. The pollen count is then calculated in grains per cubic meter of air. Pollen counts tend to be the highest early in the day, or often when the wind picks up just before a large rainstorm.

If you like dancing in the rain, or jumping in rain puddles, however, you are in luck. During a rainstorm and immediately following, pollen becomes still and dormant due to the rain making it damp and heavy. As the air becomes warm and dry following the storm, the pollen count will become potent again

Manage Your Grass Pollen Allergy

Pollen counts are never zero, nor will an allergy sufferer truly be able to avoid grass pollen in the summer. However, some practices may help decrease pollen exposures. For instance, utilizing the air conditioner while keeping the windows and doors to the home and car closed. Also, utilizing the dryer rather than the fresh breeze to dry clothing will help to decrease pollen exposures. It is especially important to keep windows closed when you or someone close mowing their grass.

Although it may seem like a good idea to avoid cutting the grass as much as possible, mowing grass often and keeping grass short actually causes the grass to release less pollen into the air. If a nonallergic friend or family member isn’t available to assist in cutting your grass, consider wearing a mask. Wearing masks will help to minimize the amount of pollen reaching the nasal passages. It is greatly beneficial for grass pollen sufferers to wear a mask when cutting grass or doing other yardwork.

Other Helpful Tips

Those with a grass pollen allergy should try to avoid heavily dense grassy areas, especially in early summer when pollen is the most dense and abundant. Although summer brings warmer temperatures. when you are out working in the yard, out at a park, or hiking it is recommended to wear long pants or long sleeve shirts in a light breathable fabric. This added layer of protection helps reduce the amount of pollen that comes in direct contact with your skin. Similarly, wearing sunglasses and hats also reduce pollen that contacts eyes or nestles in your hair.

Grass pollen allergy suffers should also make a habit of changing their clothes after coming in from being outdoors, and bathing prior to getting into bed/laying on upholstered furniture. Wash bedding in very hot, sanitizing cycles once a week in peak pollen seasons. It is also beneficial to remove shoes before entering your home. And do not forget your pets! They can be major sources of tracking grass pollen into your home. Make sure to wipes them down with a wet cloth or towel before they enter your home, and make sure to bathe them more frequently in high pollen seasons. And although not always feasible, the ability to keep your pets from sleeping in your bed, in your bedroom, or on your upholstered furniture will also greatly benefit you if you suffer from grass pollen.

Symptom Relief is an Option

If someone is unsure whether grass pollen is a trigger for their troublesome nasal congestion, runny nose, postnasal drip, sneezing, and itchy watery eyes, seeing their provider for an allergy test may provide the clarity they are looking for!
