DAYSEE (ethinyl estradiol)
Daysee is a combination hormonal medication used by females of reproductive potential to prevent pregnancy. It contains two active components: a progestin called levonorgestrel and an estrogen called ethinyl estradiol. This medication helps patients manage their reproductive health by providing a consistent method of birth control.
How DAYSEE Works
This medication works by suppressing ovulation, which is the primary way it prevents pregnancy. By stopping the release of an egg during the menstrual cycle, the combination of hormones ensures that fertilization cannot take place.
