Cigarette smoking increases the risk of serious cardiovascular side effects from oral contraceptive use. This risk increases with age and with heavy smoking (15 or more cigarettes per day) and is quite marked in women over 35 years of age. Women who use oral contraceptives should be strongly advised not to smoke.
ESTROSTEP FE SUMMARY
(Norethindrone Acetate and Ethinyl Estradiol Tablets, USP and Ferrous Fumarate Tablets*)
ESTROSTEP® Fe is a graduated estrophasic oral contraceptive providing estrogen in a graduated sequence over a 21-day period with a constant dose of progestogen. ESTROSTEP Fe provides for a continuous dosage regimen consisting of 21 oral contraceptive tablets and seven ferrous fumarate tablets. The ferrous fumarate tablets are present to facilitate ease of drug administration via a 28-day regimen, are non-hormonal, and do not serve any therapeutic purpose. Each white triangle-shaped tablet contains 1 mg norethindrone acetate [(17 alpha)-17-(acetyloxy)-19-norpregna-4-en-20-yn-3-one] and 20 mcg ethinyl estradiol [(17 alpha)-19-norpregna-1,3,5(10)-trien-20-yne-3,17-diol]; each white square-shaped tablet contains 1 mg norethindrone acetate and 30 mcg ethinyl estradiol; and each white round tablet contains 1 mg norethindrone acetate and 35 mcg ethinyl estradiol. Each tablet also contains calcium stearate; lactose; microcrystalline cellulose; and starch.
ESTROSTEP Fe is indicated for the prevention of pregnancy in women who elect to use oral contraceptives as a method of contraception.
ESTROSTEP Fe is indicated for the treatment of moderate acne vulgaris in females, ≥15 years of age, who have no known contraindications to oral contraceptive therapy, desire oral contraception, have achieved menarche, and are unresponsive to topical anti-acne medications.

Combined continuous ethinyl estradiol/norethindrone acetate does not improve forearm blood flow in postmenopausal women at risk for cardiovascular events: a pilot study. [2007.09]
OBJECTIVE: This study sought to determine whether combined continuous ethinyl estradiol and norethindrone acetate, a postmenopausal hormone therapy (HT) combination designed to have fewer side effects than cyclical therapies and therapies using medroxyprogesterone acetate (MPA), could improve vascular endothelial function in postmenopausal women with risk factors for cardiovascular disease (CVD)... CONCLUSIONS: In this older postmenopausal population with at least one cardiovascular risk factor, treatment with combined continuous ethinyl estradiol and norethindrone acetate failed to improve vascular endothelial function. The agent's proinflammatory effect or subclinical atherosclerosis in this population may have contributed to this finding.

Oral Contraceptive (OC) Estrogen Dose and Breast Proliferation [Recruiting]
The purpose of this research study is to gain a better understanding of the changes that may
occur in the breast when a woman uses an oral contraceptive (birth control pill). Some
research indicates that women who use birth control pills with lower amounts of estrogen (a
hormone in the birth control pill) may have lower breast cell growth than women who use
birth control pills with a higher amount of estrogen; this research will examine that in
detail. This research will also test whether the results found in HS-07-00269 can be
Study of the Contraceptive Efficacy and Safety of a NOMAC-E2 Combined Oral Contraceptive (COC)(P06448) [Recruiting]

17ß-estradiol (NOMAC-E2) combined oral contraceptive (COC) in healthy, sexually-active
American women at risk for pregnancy. Vaginal bleeding patterns of women taking NOMAC-E2
will be assessed and compared to those of women taking a norethisterone acetate + ethinyl
estradiol (NETA-EE) COC. The safety of NOMAC-E2 will also be assessed.
Participants will be randomized to receive either NOMAC-E2 or NETA-EE in a 3: 1 ratio.
