Sorry, didn't see this post before. I have tried claritin-D, and it seemed to help initially, but I felt very bad the next day. And since the worst days for me are the several days after the O, it wasn't that beneficial for me. As far as costs, and if it does help someone, there are also the identical generic brands. Cost shouldn't be much of a problem anyway, if in fact it does help, because it would be well worth it then. Just read all the warning labels & be careful.
