INDICATIONS AND USAGE

ORTHO EVRA® is indicated for the prevention of pregnancy.

Like oral contraceptives, ORTHO EVRA® is highly effective if used as recommended in this label. In 3 large clinical trials in North America, Europe and South Africa, 3,330 women (ages 18-45) completed 22,155 cycles of ORTHO EVRA® use, pregnancy rates were approximately 1 per 100 women-years of ORTHO EVRA® use. The racial distribution was 91% Caucasian, 4.9% Black, 1.6% Asian, and 2.4% Other.

With respect to weight, 5 of the 15 pregnancies reported with ORTHO EVRA® use were among women with a baseline body weight =198 lbs. (90kg), which constituted <3% of the study population. The greater proportion of pregnancies among women at or above 198 lbs. was statistically significant and suggests that ORTHO EVRA® may be less effective in these women.

Health Care Professionals who consider ORTHO EVRA® for women at or above 198 lbs. should discuss the patient’s individual needs in choosing the most appropriate contraceptive option.

Table 2 lists the accidental pregnancy rates for users of various methods of contraception. The efficacy of these contraceptive methods, except sterilization, IUD, and Norplant depends upon the reliability with which they are used. Correct and consistent use of methods can result in lower failure rates.
