It been working fine in my case. Actually my condition is kind of different from the usual cases. I am not using the continuously. I was initially out on the drug for a while and later I was taken off it when I changed my doctor. There was a high rise in the cholesterol level and I had to completely stop taking fatty food and then it crash down to nothing. After some time I was put the med again to maintain it a required level. It does work well for me. My last blood exam showed up 173.
