Is Yaz (drospirenone and ethinyl estradiol) a good birth control?

Yes. May cause elevated potassium. If you smoke, any birth control can be dangerous.
Yes, Yaz (drospirenone and ethinyl estradiol) is good. Yaz (drospirenone and ethinyl estradiol) is the lower dose with fewer placebo pills sister of Yasmin. It has lower estrogen (so less clot risk, but not as good for your bones) Both Yaz (drospirenone and ethinyl estradiol) and Yasmin have a diuretic effect because of the progesterone. So watch out if you have kidney disease or a family history of kidney disease. Because it had fewer placebo days, women like that. Ask your doctor what is best for you.
