Necon® 1/35, Necon® 0.5/35, Necon® 10/11, and Necon® 1/50 are indicated for the prevention of pregnancy in women who elect to use this product as a method of contraception.Oral contraceptives are highly effective.

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.TABLE I: PERCENTAGE OF WOMEN EXPERIENCING AN UNINTENDED PREGNANCY DURING THE FIRST YEAR OF TYPICAL USE AND THE FIRST YEAR OF PERFECT USE OF CONTRACEPTION AND THE PERCENTAGE CONTINUING USE AT THE END OF THE FIRST YEAR. UNITED STATES. % of Women Experiencing anUnintended Pregnancywithin the First Year of Use % of WomenContinuing Useat One Year3 - Method(1) Typical Use1 -(2) Perfect Use2 -(3) (4) Adapted from Hatcher et al., 1998 Ref. #1. 1 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. 2 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. 3 Among couples attempting to avoid pregnancy, the percentage who continue to use a method for one year. 4 The percents 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. 5 Foams, creams, gels, vaginal suppositories, and vaginal film. 6 Cervical mucus (ovulation) method supplemented by calendar in the pre-ovulatory and basal body temperature in the post-ovulatory phases. 7 With spermicidal cream or jelly. 8 Without spermicides. Chance4 - 85 85  Spermicides5 - 26   6 40 Periodic abstinence  25  63   Calendar    9    Ovulation Method    3    Sympto-Thermal6 -    2    Post-Ovulation    1  Withdrawal  19   4  Cap7 -      Parous Women 40 26 42   Nulliparous Women  20   9 56 Sponge      Parous Women 40 20 42   Nulliparous Women  20   9 56 Diaphragm7 - 20   6 56 Condom8 -      Female (Reality) 21   5 56   Male 14   3 61 Pill   5  71   Progestin Only        0.5    Combined        0.1  IUD      Progesterone T       2.0       1.5 81   Copper T380A       0.8       0.6 78   LNg 20       0.1       0.1 81 Depo–Provera       0.3       0.3 70 Norplant and Norplant-2         0.05         0.05 88 Female Sterilization       0.5       0.5 100 Male Sterilization          0.15         0.10 100
