How is Plan B different from other emergency contraceptive regimens?
Results from two randomized, comparative studies conducted by the World Health Organization (WHO) indicate that the new levonorgestrel-only regimen is highly effective and much better tolerated than the Yuzpe regimen (a 25-year old emergency contraception regimen which combines ethinyl estradiol plus norgestrel or levonorgestrel). The incidence of nausea in women taking Plan B was reduced from 50.5 percent to 23.1 percent, and the incidence of vomiting was reduced from 18.8 percent to 5.6 percent. The studies involved 2,832 women at 22 study centers in 15 countries.
