Birth Control Medications (Contraceptives) (cont.)

Biphasic Pills

Jenest, Mircette, Necon 10/11, Nelova 10/11, Ortho-Novum 10/11

Biphasic pills typically contain 2 different progesterone doses. The progesterone dose is increased about halfway through the cycle.

Triphasic Pills

Cyclessa, Estrostep, Ortho-Novum 7/7/7, Ortho Tri-Cyclen, Ortho Tri-Cyclen LO, Tri-Levlen, Tri-Norinyl, Triphasil, Trivora

Triphasic pills gradually increase the dose of estrogen during the cycle (some pills also increase the progesterone dose). Three different increasing pill doses are contained in each cycle.

Ninety-One-Day Birth Control Pills

Levonorgestrel/ethinyl estradiol (Seasonale)

These pills are monophasic birth control pills that have been approved for use on a daily basis for 84 days without interruption. Users have fewer scheduled menstrual cycles (only 1 period every 3 months). Data from clinical trials show that many women, especially in the first few cycles of use, have more unplanned bleeding and spotting between the expected menstrual periods than women taking conventional combination birth control pills.
