  • Junel ™ 21 and Junel ™Fe 28 are 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 I 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.
