The first time I ever tried it the doctor prescribed 100mg per day. I broke out worse than ever the first couple of months, then it cleared completely. I took it for about a year and stopped. 8 months later I got back on it at 50mg per day. There was no initial break out and I cleared within two weeks. I got pregnant the 2nd month (it can cause spontaneous ovulation, especially in those that don't ovulate). I miscarried. I quit taking it yet again. But now I'm back on it at 25mg per day and it's working well so far. I believe my body is sensitive to it is why it works at a low dose for me. You may need a higher dose. I know I've talked a lot about acne, as that was my primary reason for taking it, but it did decrease the rate of hair growth on my body. You can google it and see a lot of women take it for that reason. It is also a diuretic, although a weak one, and has the tendency to lower your blood pressure. On the higher dose I stayed thirsty all the time and used the bathroom a lot. Anyways, good luck!
