It's mind boggling how an allergy medication is allowed to sold and it causes more severe conditions. I've been sick 4 times in 8 weeks. with ear/sinus/respiratory infections since I started taking Claritin-D a few months ago then switched dot ZyrtecD both made me excessively thirsty with constant infections. I am medication free now and would like to know more about success with holistic tries. I have read that allergies is a symptom of dehydration, maybe an ultra hydrating product
