Hi SRS
Sorry I don't know about the regulations and laws regarding sending antihistimines to the US by mail, but if there is a quota on the number of packages allowed for individual shipments, perhaps you can have more than one person send you some packages and split up the supply. I would gladly send you some from here.

I know some of the frustrations regarding getting a reasonably priced supply of antihistamines as both my husband and eldest daughter have severe allergies and I have been purchasing antihistimanes for years.

What is the formulation of Allegra D? It is sometimes even cheaper to buy a generic drug here of the same formulation rather than the brand name and as a result we now purchase the exact equivalent of Reactine through Canada Superstore here. I think if you are considering a years supply, you might get whoever is sending it to you to check the expirary date, although that is usually not a problem.

We used to have to get Reactin for my daughter by prescription when she was younger, in a bottle of 100 pills, as it wasn't, at one time, available over the counter here. It was oddly, far cheaper that way , despite the dispensing fee. When it became available over the counter, we had to buy it that way and not only did it cost an arm and a leg by comparison, we had all that superfluous packaging to boot, for just a small quantity of pills.

Regardless if I can be of help or not, good luck on your quest.
Susan
