How Drospirenone–Ethinyl Estradiol Works

Drospirenone–ethinyl estradiol prevents pregnancy through several hormonal mechanisms.

These hormones help:

Prevent ovulation, meaning the ovaries do not release an egg

Thicken cervical mucus, making it more difficult for sperm to reach the egg

Alter the uterine lining, reducing the chance of implantation

Drospirenone also has mild anti-androgenic and anti-mineralocorticoid properties, which may help reduce:

Acne symptoms

Fluid retention in some individuals

The medication helps regulate reproductive hormones but does not permanently alter fertility.
