Loestrin 24 Fe is indicated for the prevention of pregnancy in women who elect to use oral contraceptives as a method of contraception. Oral contraceptives are highly effective. Table 2 lists the typical unplanned pregnancy rates for users of combination oral contraceptives and other methods of contraception. The efficacy of these contraceptive methods, except sterilization, the IUD, and the Norplant® system, depends upon the reliability with which they are used. Correct and consistent use of methods can result in lower failure rates. In a clinical study, 743 women, 18 to 45 years of age, were treated with Loestrin 24 Fe for up to six 28-day cycles providing a total of 3,823 treatment-cycles of exposure. A total of 583 women completed 6 cycles of treatment. There were a total of 5 on-treatment pregnancies in 3,565 treatment cycles during which no backup contraception was used. The Pearl Index for Loestrin 24 Fe was 1.82.
