"Was on this for about a year, completely cleared up my premenstrual acne. Normally I would only get a couple pimples before each period but this medication didn't cause any, great clear skin. Normal periods, light to moderate lasting about 5 days. No out of normal weight gain, no headaches or mood swings. I'm only giving it 9 stars because it really dried me out down there, needed lube sometimes. Other than that, I'd recommend it if you have a tendency to get premenstrual acne."
