Title: Contraception system and method
Abstract:A method of contraception is disclosed which comprises a two-stage protocol. In the first stage, an estrogenic compound in a first composition is administered daily as the sole contraceptively active substance to a human female from about Day 2 to about Day 7 of her menstrual cycle, where Day 1 is the first day of menses. The second stage of the protocol occurs immediately thereafter during which at least one follow-up composition containing a progestin is administered daily to the same human female. The follow-up composition can contain a progestin as the sole contraceptively active ingredient, or can contain a combination of an estrogenic compound with a progestin in different weight ratios. A drug delivery system containing daily dosage units is also described.
