How long does a dust mite allergic reaction last?

How long does a dust mite allergic reaction last?

It depends...: On the amount and duration of exposure. If you're allergic to dust mites and you fluff up a pillow on the way to the washing machine, probably 30 minutes. If you sleep on a pillow without an allergy cover, the all-night-long exposure might last a couple of hours, or if you're highly allergic to dust mites, it might last all day.

Can stress (or anything other than the allergen) be a factor in the frequency or severity of a dust mite allergic reaction?

Can stress (or anything other than the allergen) be a factor in the frequency or severity of a dust mite allergic reaction?

Stress worsens: Our bodies are so complex, and we really only understand a fraction of how our bodies' systems interact with our environment. In general, chronic ongoing stress seems to worsen many illness. So yes, I'm sure stress has the potential to worsen allergy. It's good to make a concerted effort to lessen overall stress.

Need a futon for my new apt. Tend to have allergies. If I get a used one, could I get a dust mite allergy?

Not really: If you're genetically predisposed to develop a dust mite allergy, you will be exposed to enough dust mite allergen that an allergy will develop. It may come on faster if you have huge, frequent exposures, but an old futon in and of itself won't cause the allergy. Beat the cushions (outdoors!) when you first get it, then get it steamcleaned to remove as much dust mite allergen as you can.

Child rash very faint pink spots flat and don't itch on cheeks and torso no other sym besides congestion from allergies (dust mite) should I worry?

Child rash very faint pink spots flat and don't itch on cheeks and torso no other sym besides congestion from allergies (dust mite) should I worry?

Naw: Sounds to me like Fifth Disease, 6th disease, or another viral rash. These will often happen after a fever and are usually a sign that the illness will soon be over. Another possibility is an allergic reaction, which would improve with antihistamine.

Dust mite barrier: Covering your mattress with an impermeable dust mite barrier and washing sheets in hot water weekly as well as removing extra pillows and thick comforters are the most important steps to avoid dust mite allergy reactions.

I have dust mite allergies and my right ear goes almost deaf is something swelling up or is it fluid buildup also it tends to happen after headphones?

I have dust mite allergies and my right ear goes almost deaf is something swelling up or is it fluid buildup also it tends to happen after headphones?

Not from mites: House dust mite allergy may cause nasal congestion and inner ear issue but would not be linked to headphones. Get your ears checked to make sure that earwax is not the issue. I suspect that you have dry earwax which swells up from the sweating after wearing headphone. Let me know if my hunch is right.

How do I know when my son has allergies or a virus? He has had stuffy/runny nose for a month no other symptoms. He does have a dust mite allergy

How do I know when my son has allergies or a virus? He has had stuffy/runny nose for a month no other symptoms. He does have a dust mite allergy

Virus vs. Allergy: Initially, both viruses and allergies can produce similar symptoms such as clear runny nose, sneezing, watery eyes, slight cough, etc. However, symptoms from a viral infection should resolve within 10-14 days, while allergy symptoms will linger until treated or until the allergen is removed.

How long do the symptoms of a dust mite allergy usually last for?

Hard to say: Acute symptoms due to a specific exposure can last for one to two hours; less if treated immediately with antihistamines. But dust mite allergen is very common in the environment, so continued exposure throughout the night and day can cause continuous symptoms. If taking an antihistamine on a regular basis doesn't help, see your primary physician or allergist.

My doctor says I'm allergic to dust mite (f) but not (p). What's the difference? What do the p and f mean?

Subtle Difference: Der p1 (Dermatophagoides pteronyssinus) and Der f1 (Dermatophagoides farinae) are the two major mite allergens. If you are allergic to one and not the other it doesn't make much difference. Basically you have a sensitivity to dust mite and should practice avoidance measures: dust mite covers to mattress and pillows, wash sheets on hot cycle once weekly, remove upholstered items from bedroom, etc.

What do you suggest if my doctor says I'm allergic to dust mite (f) but not (p). but I don't know the difference! What does the p and f mean?

2 species: There are 2 species of dust mite, dermatophagoidies pterynissinus and dermatophagoidies farinae. The f and p refer to the species. Clinically they live in the same places and trigger the same type of reactions. Use of dust mite covers on pillows and mattresses can help.

I have asthma and dust mite allergy for almost last 10 years. Can I take levolin inhaler and cetrigine 10mg together for asthma and dust mite allergy?

Non specific: Asthma and allergy medicines would help control your symptoms, but if you are sure allergic to dust mites, you first need to avoid exposure as much as you can by using environmental control measures, and if still symptomatic, ask an experienced allergist whether you are a candidate for specific immunotherapy against dust mites, goodluck

I have runny nose & congestion. But I'm not sick. Could it be from the cat dander, that got blown about with the heater? I'm allergic, but tried to put cat in other room. I have dust mite bedding.

I have runny nose & congestion. But I'm not sick. Could it be from the cat dander, that got blown about with the heater? I'm allergic, but tried to put cat in other room. I have dust mite bedding.

Yes: If you are allergic to cat dander then it doesn't matter where the cat is inside the house. Unless you have a hepa filter in the furnace, the dander will be recirculating constantly when the furnace is on. Cat dander can be detected even 2 years after removal of the cat. Solution? Antihistamine-> removal of the cat following by thorough cleaning -> allergist.

Have phlegm (throat) since Feb. I don't have cough. X-ray normal. Allergic to dust mite. What to do Doctor?

Post nasal drip: If you have a confirmed dust mite allergy would suggest proper avoidance measures: dust mite covers on mattress and pillows, wash sheets in hot water cycle once weekly. Treat nasal symptoms with daily intranasal corticosteroid spray (can get other-the-counter now). These measures should reduce symptoms from dust mite allergy.
