User Reviews for Allegra-D 24 Hour

The antihistamine effects aren't as strong as immediate release diphenhydramine (Benadryl), but it still works pretty well and the continuous release is a nice thing to have.

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.

Efficient for allergies, but bad side effects. I experienced many of them: ringing in my ears, insomnia, unusual behavior, anxiety, unable to concentrate, itchy skin, and a couple more.

I tried some samples my doctor had supplied for allergy symptoms. It has helped my allergy symptoms and also seems to be an appetite suppressant. I had no adverse side effects. I got a prescription and wow is it expensive! My insurance plan wouldn't pay for i.

This medicine works really good for me.
