Thanks for the clarification, Heather!

Apparently Heather, the question here isn't safety....it's MONEY!!   The amount of money the pharmaceutical would have to spend to get it past the FDA is too much considering that it's merely an antihistamine!  They don't feel that it's worth the investment for them!!   It's cheap medicine!  I pay no more than about $6 dollars for 20 pills and in comparrison to Allegra, which is about $20 dollars for 10 pills, you've got quite a difference there!!  

I suggest that you do like some of the others are doing, find out about those compounding companies for that seems to be the best deal for those in the States.   The vast majority of us do well on Ketotifen and it's a whole lot cheaper than gastrochrom.  Yet, Gastrochrom apparently has a few benefits that I don't think Ketotifen will give you and apparently there are those who have increased energy with gastrochrom.  I've not noticed that with Ketotifen and I take 6mg a day.   So, even though gastrochrom seems to go right through you, it does have some benefits.   But for those of us who are counting every penny, then I'd go for the ketotifen!!!

Hope this helps!
