Sronyx: An Overview

Sronyx is a generic combination hormonal birth control pill used to prevent pregnancy. It belongs to a class of medications called oral contraceptives and contains two synthetic female hormones: ethinyl estradiol, which is an estrogen, and levonorgestrel, a progestin. The 28-day cycle consists of 21 active tablets containing these hormones and seven inert (placebo) tablets.

The primary way Sronyx works is by preventing ovulation, the release of an egg from the ovaries each month. The hormones also alter the cervical mucus, making it thicker and more difficult for sperm to travel through, and they change the lining of the uterus, making it less receptive to implantation should an egg somehow be fertilized. In addition to pregnancy prevention, Sronyx may be prescribed for other reasons, such as regulating periods, treating acne, and reducing the risk of ovarian cysts.
