I guess I am one of those 1% for Loratidine. I never looked at the list of side effects b/c it was the only med I was taking when I felt like I almost couldn't stop moving even though I didn't feel like doing anything. And at night I would get restless legs all night and feel like I needed to run instead of sleep (and I'm not a runner). I tried it several times, hoping to get allergy relief, but it was never worth the side effects.

I've taken Zyrtec without a problem.
