If I take the 30 mg dose Allegra helps my allergies (mostly Alder and grasses, itchy, runny nose, chills and puffy eyes) and energy level. If I take 60 mg I get a severe, itchy, bumpy rash on my face and neck and into my hairline. If the low dose isn't enough to help my alleriges I guess I will just deal with the allergies instead of the rash.
