Daflon 500 for CVI

I've been using Daflon 500 for CVI (lower legs) for almost two years. My doctor knows that I'm using it. I believe it has helped me a lot, although I can't be sure of that. My CVI improved under Daflon, and didn't get any worse for about a year and a half. Since I dropped down to one pill/day my CVI has worsened. I was going to go back to 2 pills/day after my new supply arrived. Is anyone else on this list using Daflon? Today I received a shock when I got a letter from U.S. Customs. They have confiscated my latest order of Daflon 500 ($150 worth) because it is not approved by the FDA. The FDA has had 12 years to approve or disapprove it and they have done NOTHING because it isn't made by a US pharmaceutical. My order was coming from Thailand and I was wondering why it was late, as I've been out of pills for a few days. Customs gave me the option of allowing them to destroy it, or send it to the FDA. Our government and the FDA have really let us down! I keep my legs elevated most of the day, and I am wearing extra-compression socks (the $400 ones, which my insurance company won't pay for), so there is not much more I can do. I sure don't want to go back to having open sores, but it looks like I'm headed in that direction. Dick
