I took Yaz for 3 months. I had been on Mircette prior to this for about 7 years. When I switched to Yaz, I became a completely different person. I had fits of rage. I would become irate and angry very easily. I wasn't depressed or any side effects like that, but it made me VERY irritable.
But worse than that, is that I developed skin discoloration from this medication. My face has weird patches of discoloration that worsen in the sun. Even though I have switched to Mircette, and the discoloration still persists. None of this started until I began Yaz.
