Dust mite allergy is an IgE mediated Type 1 hypersensitivity reaction to dust mite allergens, commonly found in household dust. This activity reviews the evaluation and treatment of dust mite allergy and highlights the role of the interprofessional team in improving care for patients with this condition. Dust mite allergy is an allergic reaction to tiny bugs that commonly live in house dust. Signs of dust mite allergy include those common to hay fever, such as sneezing and runny nose. Many people with dust mite allergy also experience signs of asthma, such as wheezing and difficulty breathing. House dust mites are present indoors wherever humans live.[15] Positive tests for dust mite allergies are extremely common among people with asthma.

This treatment can be particularly effective for those with severe allergies who have not responded well to other treatments. As always, it's important to discuss this option with your healthcare provider to ensure it's the right choice for you. To learn more about managing dust mite allergies, click here.

You should consult a doctor for a house mites allergy if you experience persistent symptoms that interfere with your quality of life, despite attempts at self-care and prevention. Also, OTC medications do not provide sufficient relief or if you experience severe symptoms such as difficulty breathing. Pet cats are the most problematic animal in terms of allergen production, due to their behaviour of frequent grooming. Dogs come second but any animal can be a cause of an allergic reaction.
House Dust Mite Allergy: Diagnosis, Treatment & Prevention
It involves placing a tablet under the tongue that contains a small amount of the allergen. Studies show that this method can significantly reduce allergy symptoms and the need for medications. House dust mite allergic rhinitis, often referred to as hay fever, presents symptoms including runny or stuffy nose, sneezing, and itchy or watery eyes. Postnasal drip, which can lead to coughing, is also a common symptom.
What can I expect if I have a dust mite allergy?
Room by room, you can take these steps to have an allergen-free abode. Learn about dust mites and how to minimize exposure in the home in the video below. Singulair increases the risk of severe mental health side effects, such as suicidal thoughts and actions. Because of this, it should only be used when other suitable allergy medications aren’t available.
How to Protect Against Dust Mites
This process can happen early in life and may lead to problems like runny nose and asthma, known as the allergic march. Dust mite allergies stem from microscopic creatures called dust mites, closely related to ticks and spiders. These minuscule arthropods thrive in warm, humid environments, measuring 0.2–0.3 millimeters in length, and cannot be seen without magnification.
You might have symptoms until you reduce or get rid of dust mites. If you have a dust mite allergy, the first time you encounter dust mite proteins, your body responds by creating immunoglobulin E (IgE). IgE is antibodies that your immune system makes to “attack” allergens, even though these allergens might not be harmful. Once you encounter dust mite proteins again, your immune system has a greater response. A dust mite allergy causes your immune system to react to proteins found in dust mites. Symptoms include congestion, watery eyes, runny nose and sneezing.
Diagnosis of House Dust Mite Allergy
If required, both house dust mite and pet allergy can be diagnosed with skin prick tests. This is usually done in a hospital by either an allergy specialist, an immunologist or perhaps a skin specialist (dermatologist). Aero-allergens rarely cause severe allergic reactions such as anaphylaxis. They are, however, some of the most common causes of allergies in general.
Dust mites have proteins in their feces (poop) and dead bodies. Usually, these substances — called allergens — are harmless. However, your immune system views them as harmful “invaders,” like bacteria or viruses, and responds to get them out of your body. Using CERTIFIED asthma & allergy friendly® products in your home can help you have a healthier indoor environment, as well as reduce allergens. Because appointments can be brief and there's often a lot of ground to cover, it's a good idea to prepare before you go.
An allergy is the immune system’s response to an unknown substance that’s not usually harmful to your body. People who are allergic to dust mites have bad reactions to the remnants of the bugs. These remnants include tiny mounds of feces and decaying bodies. If you have dust mite allergy symptoms, it’s a good idea to see your healthcare provider. An allergist is a healthcare provider who specializes in allergies.
Once you’re no longer around dust mite allergens, your symptoms usually go away after a few hours. If you have severe dust mite allergies, your symptoms may last for several days. Allergic reactions typically occur within 15 minutes of exposure to dust mite proteins. Reactions may include skin discoloration (red, gray or white) or raised, round spots called wheals that look like bug bites.
For optimal results, use a vacuum with a HEPA filter that can trap tiny particles like dust mite allergens efficiently. To prepare for your appointment, make a list of the symptoms you've been experiencing, noting their frequency and any patterns you've noticed. It's also essential to list all prescription and over-the-counter (OTC) medicines you're currently taking. Be ready to answer questions about your home environment and cleaning habits, as this can provide valuable information about potential exposure to dust mites. House mites allergies occur when an individual's immune system overreacts to proteins found in the feces and bodies of dust mites. The immune system identifies these proteins as harmful, triggering an allergic reaction.
Bedbugs are larger than dust mites, and can be seen with the naked eye. They’re sometimes confused with dust mites because they live in bedding, carpets, and curtains. And like dust mites, they can also cause allergic reactions. Dust mites make their homes in places where dead skin cells are most likely to accumulate, such as bedding, furniture, and carpeting. Rugs and stuffed animals also make good homes for dust mites. The reason why dust mites are so prevalent in people’s homes is that they feed off of dead skin cells.
Short-term relief is provided through short-acting beta-agonists (SABA). The long term relief is provided by anticholinergics, long-acting beta-agonists (LABA), and low dose inhaled corticosteroids. Oral corticosteroids are used in acute exacerbations of asthma. Leukotriene antagonists and mast cell stabilizers may be useful.
The first treatment for controlling dust mite allergy is avoiding dust mites as much as possible. When you minimize your exposure to dust mites, you can expect fewer or less severe allergic reactions. However, it's impossible to completely eliminate dust mites from your environment. Symptoms of an allergic reaction to dust mites, or house dust mite (HDM) allergy, typically involve the respiratory system and skin.
To diagnose a dust mite allergy, your doctor may give you a physical exam and discuss your symptoms. If your doctor thinks you have a dust mite allergy, they may suggest a skin or blood test. If you have symptoms year-round, you could have a dust mite allergy. Treatment includes reducing exposure to house dust mite through reduction/ eradication techniques. In people allergic to dust mite, it is often not the mite itself but proteins in their droppings which cause the allergy symptoms.
