Norethindrone acetate and ethinyl estradiol tablets and ferrous fumarate tablets are indicated for the prevention of pregnancy in women who elect to use combined oral contraceptives as a method of contraception. Norethindrone acetate and ethinyl estradiol tablets and ferrous fumarate tablets are indicated for the treatment of moderate acne vulgaris in females, ≥ 15 years of age, who have no known contraindications to combined oral contraceptive therapy, desire oral contraception, have achieved menarche, and are unresponsive to topical anti-acne medications. Norethindrone acetate and ethinyl estradiol tablets and ferrous fumarate tablets should be used for the treatment of acne only if the patient desires a combined oral contraceptive for birth control and plans to stay on it for at least 6 months. Combined oral contraceptives are highly effective for pregnancy prevention. Table 2 lists the typical accidental pregnancy rates for users of combination oral contraceptives and other methods of contraception. The efficacy of these contraceptive methods, except sterilization, depends upon the reliability with which they are used. Correct and consistent use of methods can result in lower failure rates. ‡ Among couples attempting to avoid pregnancy, the percentage who continue to use a method for 1 year. * Among typical couples who initiate use of a method (not necessarily for the first time), the percentage who experience an accidental pregnancy during the first year if they do not stop use for any other reason. † Among couples who initiate use of a method (not necessarily for the first time) and who use it perfectly (both consistently and correctly), the percentage who experience an accidental pregnancy during the first year if they do not stop use for any other reason. § The percentages becoming pregnant in columns (2) and (3) are based on data from populations where contraception is not used and from women who cease using contraception in order to become pregnant. Among such populations, about 89% become pregnant within one year. This estimate was lowered slightly (to 85%) to represent the percent who would become pregnant within one year among women now relying on reversible methods of contraception if they abandoned contraception altogether. ¶ Foams, creams, gels, vaginal suppositories, and vaginal film. #Þ Cervical mucus (ovulation) method supplemented by calendar in the pre-ovulatory and basal body temperature in the post-ovulatory phases. ß With spermicidal cream or jelly. à Without spermicides. è The treatment schedule is one dose within 72 hours after unprotected intercourse, and a second dose 12 hours after the first dose. The Food and Drug Administration has declared the following brands of combined oral contraceptives to be safe and effective for emergency contraception: Ovral (1 dose is 2 white pills), Alesse® (1 dose is 5 pink pills), Nordette® or Levlen® (1 dose is 4 light-orange pills), Lo/Ovral® (1 dose is 4 white pills), Triphasil® or Tri-Levlen® (1 dose is 4 yellow pills). ð However, to maintain effective protection against pregnancy, another method of contraception must be used as soon as menstruation resumes, the frequency or duration of breastfeeds is reduced, bottle feeds are introduced, or the baby reaches 6 months of age. Norethindrone acetate and ethinyl estradiol tablets and ferrous fumarate tablets were evaluated for the treatment of acne vulgaris in two randomized, double-blind, placebo-controlled, multicenter, Phase 3, six (28-day) cycle studies. A total of 296 patients received norethindrone acetate and ethinyl estradiol tablets and ferrous fumarate tablets and 295 received placebo. Mean age at enrollment for both groups was 24 years. At six months each study demonstrated a statistically significant difference between norethindrone acetate and ethinyl estradiol tablets and ferrous fumarate tablets and placebo for mean change from baseline in lesion counts (see Table 3 and Figure 2). Each study also demonstrated overall treatment success in the investigator’s global evaluation. Patients with severe androgen excess were not studied. *Numbers rounded to nearest integer †Limits for 95% Confidence Interval; not adjusted for baseline differences Norethindrone acetate and ethinyl estradiol tablets and ferrous fumarate tablets users who started with about 74 acne lesions had about 42 lesions after 6 months of treatment. Placebo users who started with about 72 acne lesions had about 49 lesions after the same duration of treatment. Figure 2.
