I've been on Yasmin for about 2 years. It cleared my skin up really well, but gave me serious joint pain. At month 2, I went back to the doctor and he said that the side effect wasn't reported by anyone he was aware of and that the symptoms were probably unrelated. He said to stay on it a few months, and if it didn't get better, see a rheumatologist. Anyway, I stayed on it and didn't go off because I was pleased with the skin-clearing effect. The joint pain continued to get worse and my hair started falling out in clumps (it was just so dry), and last month I just got tired of it and started taking Alesse instead. In the three weeks I've been off Yasmin, my joint pain has almost completely disappeared, my hair is more healthy, and I'm sleeping much better (it's hard to sleep when your joints ache constantly!). Other than the severe joint pain and hair/skin drying, I didn't have any problems...but those side effects were severe enough to me that I probably will not go back on Yasmin again.
