I have had allergies to wind born irritants all my life. This is my "go-to" medication when allergens get my eyes itching and I start sneezing.
I prefer the 12-hour dose size, as by the end of 12 hours the allergens are usually finished being blown around by the wind. If they haven't, I can take another 12-hour dose.
I do take "allergy" shots, and am down to once a month, but my allergies still flare up all too often. That is when I turn to Zyrtec-D, as it will alleviate my symptoms within a half hour.
Yes, I'd recommend this product
