This medication is a combination of 2 hormones: an estrogen (ethinyl estradiol) and a progestin (drospirenone). This product is used to prevent pregnancy. It works mainly by preventing the release of an egg (ovulation) during your menstrual cycle. It also makes vaginal fluid thicker to help prevent sperm from reaching an egg (fertilization) and changes the lining of the uterus (womb) to prevent attachment of a fertilized egg. If a fertilized egg does not attach to the uterus, it passes out of the body. (Please consult your physician before taking any medication)
