Hi Welcome to HCM A high number of eosinophils indicates allergies or parasitic infections. Sneezing might be due to some allergy. Allergy to pollen, mold, dander, or dust and may be due to viral infections like common cold, upper respiratory tract infections, nasal irritants such as dust and powders. The best way to control sneezing caused by allergies is to avoid exposure to the offending allergen. To reduce your exposure, remove pets if any,from the home to eliminate animal dander, use air filtration devices to reduce pollen in the air, travel to areas with low pollen counts. When allergies are the culprit, antihistamines are the first line of therapy which you are taking. Nasal steroid sprays may be helpful in more chronic conditions. For sneezing not caused by an allergy, the problem will disappear when the underlying disorder is cured or treated. Hope i have provided the information you needed. Take care.
