Drospirenone / ethinyl estradiol
"I have been on Gianvi for about 5 years or more. I have severe PMDD problems, as well as a family history of severe period problems as well (too heavy bleeding, cramps, etc). Yaz has improved my PMDD symptoms by about 80%. It also makes my periods very light and easy with no cramps. I also have bad hormonal acne and Yaz clears my skin and makes it glow. I still get 1 or 2 pimples around my period but that's it. I went off Yaz for 9 months and it gave me horrible rebound cystic acne that makes me reinstate (my skin was getting ruined!) I am staying on it indefinitely and am fine with that. I love it."
