Review: Effective Allergy Relief Assistance And A Terrific Value - I have allergies year round here in the San Francisco Bay Area; they seem to get worse each year. These 25 mg Allergy Relief pills are just as effective as the more expensive name brand product. They do not completely get rid of my allergy symptoms, but they do lessen the severity of them. The pills do not make me drowsy, but they sometimes dry out my facial skin and mouth. These are effective at lessening my dog Sid's year round allergies, too. This 600 count bottle is a terrific value. I highly recommend this product.
Review: Allergy med - Great product for a great price
