It dries up itchy throat and watery eyes within 20 minutes. The price is always lower than the name brands because it is a generic. It has the same percentage of main ingredients as the name brand. I am 100% satisfied with this product.
This product is not similar to Clartin-D. To buy something similar to that Clartin-D you would have to purchase the item at your local pharmacy. The product is only behind the counter. This product is however similar to Allegra and should work exactly the same.
