LESSINA-28 (ethinyl estradiol) · Teva
Lessina-28 is a combined oral contraceptive (COC) indicated for use by females of reproductive potential to prevent pregnancy. It consists of a 28-day cycle containing the progestin levonorgestrel and the estrogen ethinyl estradiol. This medication provides a reliable method of hormonal birth control for patients seeking to avoid conception.
How LESSINA-28 Works
Lessina-28 prevents pregnancy primarily by suppressing ovulation via the inhibition of gonadotropin secretion. Secondary mechanisms that contribute to its efficacy include increasing cervical mucus viscosity (which inhibits sperm migration) and altering the endometrium to discourage implantation.
