I've been taking 10mg of the chewable Pepcid for about 3 years now and it seems to do the trick. It is still slightly noticeable (particularly in my eyes which go a bit red) but it's definately not as red on my face compared to not taking it. I might try increasing the dosage to 20mg and see if that reduces it even more.  It's become almost a habit now to make sure that I have some in my pocket before I go out. I don't tend to bother if I'm just drinking at home. Found this useful site which explains the problem and how to buy the solution: http://asian-flush.net/
