I have a dust mite allergy. Is allergen immunotherapy safe?

Question

Hello doctor,

For the past few months, I have been struggling with constant sneezing, a runny nose, and watery eyes, especially in the mornings.

My IgE levels were slightly elevated in the blood test, and the skin prick test suggested dust mite sensitivity.

I was given Cetirizine, but it makes me very sleepy and hard to focus at work. Can you give your suggestion on the following:

Are there newer or less sedating medicines that can help manage my condition better?
Should I also think about allergy shots or immunotherapy if the symptoms continue year-round?
Lastly, are there simple home measures, like air filters or bedding covers, that actually help?

Kindly suggest.

Hello,

Welcome to icliniq.com.

I understand your concern.

It sounds like you are dealing with allergic rhinitis, which can be very frustrating when symptoms affect your daily comfort and concentration.

Since your tests show dust mite sensitivity, your symptoms make sense, and the fact that Cetirizine causes drowsiness is quite common.

You could try newer, less sedating antihistamines such as Fexofenadine, Loratadine, or Desloratadine, which are equally effective for most people and cause much less sleepiness.

Nasal steroid sprays like Fluticasone or Mometasone are also very effective when used regularly and can greatly reduce sneezing, congestion, and a runny nose.

If your symptoms persist year-round despite these medicines, you may be a good candidate for allergy immunotherapy, either through allergy shots or sublingual tablets. These treatments work gradually to desensitize your immune system and can provide long-term relief over several years.

At home, environmental control measures make a real difference and can significantly reduce allergen exposure. This includes:

Use dust mite-proof covers for pillows and mattresses.
Washing bedding weekly in hot water.
Keeping humidity below 50 percent
Vacuuming with a HEPA (high-efficiency particulate air) filter.
Air purifiers with HEPA filters also help, especially in the bedroom.
Try to keep pets out of sleeping areas and avoid heavy carpets or stuffed toys that collect dust.

With a combination of updated medication, consistent nasal treatment, and allergen control, you should see much better symptom control and improved focus during the day.

I hope this helps.

Thank you.
