How to tell if your symptoms are caused by allergy symptoms, cold, or flu.

The severity of symptoms and how long they last can be a good indicator of the difference between allergies and a cold or flu. Still not sure? Refer to this chart and consult your doctor.

Ragweed? More like “dragweed”.

We’ve added a “D”, too – for “decongestant”. Congestion happens and Allegra-D is here to help.

Hands down, no question, congestion can be the worst. It can be the result of allergens like pollen, pet dander or mold. When irritated, nasal tissues and blood vessels swell with excess fluid, leaving you with that "why-is-this-happening-to-me" stuffy feeling.
