allergic rhinitis
"Allergra D, is the best medicine for my allergies and I've taken just about every over the counter medicine. I have terrible hay fever and I'm allergic to almost all grasses, trees, pollen in my region (Midwest- Illinois). My allergist suggested that I move to Arizona. 
Unlike Allegra D 12-hour, I'm having trouble with side effects: insomnia, nausea, heart burn, cramping. The stomach-related effects are beginning to taper off, but the insomnia isn't."
