Yasmin is a monophasic oral contraceptive containing ethinyl estradiol and drospirenone. It is more than 99% effective in preventing pregnancy. Yasmin may reduce menstrual cramps and make cycles more regular. The incidence of spotting and breakthrough bleeding is low.
Yasmin prevents ovulation (the release of an egg from an ovary) and also causes changes in the cervical and uterine lining, making it harder for sperm to reach the uterus and harder for a fertilized egg to attach to the uterus.
Yaz vs Yasmin
Both Yasmin and Yaz are made by Bayer, contain the same hormones, and are very effective - 99% chance of not getting pregnant.
They have two main differences to take into account before choosing one over the other.
Both contain the same amount of drospirenone - 3 mg, but Yaz contains less of ethinyl estradiol - 0.02 mg, while Yasmin contains 0.03 mg of ethinyl estradiol.
Another difference between Yaz and Yasmin is in the number of active pills in earch set. Yasmin has 21 active pills and 7 placebo pills whereas Yaz has 24 active pills and only 4 placebo pills. Yaz markets the idea of shorter periods. Even though it operates on a 28-day cycle, since there are only 4 placebos, Yaz regulates the woman to a shorter menstruation.
According to the discussions, the side effects seem to be more pronounced in case of Yaz.
Ocella vs Yasmin
Ocella is a generic version of Yasmin, released in 2008 by Teva Pharmaceuticals USA.
How Yasmin differs from other Pills?
Yasmin, Yaz, and Ocella contain a novel progestin - drospirenone. Drospirenone is the only progestin that has anti-mineralocorticoid and anti-androgenic properties.
Drospirenone is an analogue of spironolactone and, like spironolactone, affects the sodium and water balance. While drospirenone increases sodium and water excretion, it does not promote potassium deficiency.
Due to its antiandrogenic diuretic properties, Yasmin has the extra benefit of improving acne, seborrhea, and hirsutism (excess body hair) as well as providing good weight stability - or even slight weight loss - from decreased water retention.
Alternatives to Yaz and Yasmin
Two articles published in 2011 in the British Medical Journal reported that drospirenone-based birth control pills, such as Yasmin, lead to a higher risk of blood clots compared to pills containing levonorgestrel.
The safer alternatives are pills that contain estrogen and older progestin, levonorgestrel:
