Spring heralds the arrival of blooming flowers and vibrant outdoor scenes, but it also brings a surge in pollen which aggravates allergies for many. Dr. David Corry, an allergist at Baylor College of Medicine, discusses strategies to combat allergies throughout this season.
In a comparison of the current allergy season to previous ones, Dr. Corry states, "This year’s allergy season is about the same – nothing unusual." He highlights tree pollen, particularly from oaks, as the main trigger, mentioning that it accounts for about 95% of the pollen in the air.
Rain can provide temporary relief by washing pollen from the air, but it has its downsides. "Rain is a mixed blessing when it comes to allergies... it starts to cycle all over again," Dr. Corry explains. The moisture can lead to mold growth and cause weeds and grass to proliferate, further exacerbating allergy issues.
Addressing the concern of antihistamines losing their effectiveness, Dr. Corry notes, "The severity of allergies is dependent on the level of allergens in the air." He advises adjusting the dosage in consultation with a physician to manage symptoms effectively. A separate condition, sinusitis, may mimic allergy symptoms but often requires different treatments.
To mitigate allergies, Dr. Corry suggests medical treatments such as oral antihistamines, intranasal antihistamines, and internasal steroids, recommending nasal steroid sprays like fluticasone for relief. For those with eyes irritated by allergens, saline or medicated eyedrops can help.
Dr. Corry also offers preventive measures, such as wearing masks and goggles during outdoor activities and making home environment adjustments to reduce exposure to allergens like dust mites and pet dander. He advises, "Consider removing all carpeting and cloth furniture in the home." Regular cleaning with a vacuum equipped with a HEPA filter is emphasized as essential.
As for medication timing, Dr. Corry believes it is generally flexible, stating, "Most antihistamines sold today do not cause drowsiness for most people." Nonetheless, taking them at night can be beneficial for those who do experience drowsiness.
Daily, year-round use of allergy medications is not advised due to potential risks. Dr. Corry warns, "Taking antihistamines chronically without interruption is a risk factor for onset of dementia." Alternative treatment options, such as immunotherapy, should be discussed with an allergist if standard medications fail.
