I have been taking Yaz for 4 years (after switching from ortho tri cyclen) and have never had any problems with mood, weight, acne, sex drive, etc. I was given Gianvi as the generic and like any responsible woman, started to research. All I have found are horror stories from women who switched from Yaz to Gianvi (weight gain, extreme mood swings, anxiety, headaches, lethargy, acne, etc.).
The generic is supposed to be the same thing. So what I am really curious about is: if Gianvi is supposed to be the generic, why are so many women having such extreme side effects?
