Mechanism

Combination oral contraceptives prevent ovulation by suppressing LH and FSH levels, leading to an absence of a mid-cycle LH surge and diminished endogenous steroid levels. The combination of estrogen and progestin synergistically decreases plasma gonadotropin levels and suppresses ovulation more consistently than either component alone.

Indications

ContraceptionContraception in women who are likely to comply poorly with combined oral contraceptives (restricted use)

Dosing
