QUARTETTE (ethinyl estradiol)

Women's Health Approved 2013-03-28

Quartette is an extended-cycle combination oral contraceptive containing levonorgestrel (a progestin) and ethinyl estradiol (an estrogen). It provides 91 days of continuous hormonal coverage, resulting in four withdrawal bleeding periods per year instead of thirteen.

How QUARTETTE Works

Quartette prevents pregnancy primarily by suppressing ovulation via inhibition of gonadotropin secretion. Secondary mechanisms include thickening of cervical mucus to inhibit sperm migration and alterations to the endometrium to reduce implantation likelihood.
