I've been taking Allegra M every day for the past three years, but recently it feels like my allergies are just as bad, with a runny nose and watery eyes, and I'm constantly sneezing. It gets really bad sometimes. I also use Aerocart rotacaps occasionally when at night it feels like I can't breathe properly. Why is this happening, and what should I do about it?

try to find the allergen and avoid it. try taking tablet. montec lc
