State of emergency contraception in the U.S., 2018

Abstract: Emergency contraception is indicated in instances of unprotected sexual intercourse, including reproductive coercion, sexual assault, and contraceptive failure. It plays a role in averting unintended pregnancies due to inconsistent use or non-use of contraception. Options for emergency contraception vary by efficacy as well as accessibility within the U.S. This paper provides an overview of levonorgestrel (Plan B One-Step and generic counterparts), ulipristal acetate (sold as ella), and the copper intrauterine… Show more

“…The Cu-IUD is the most reliable EC method with a failure rate of <0.1%, and it is also effective after ovulation has occurred [ 6 ]. However, access to this form of EC is made difficult in that a gynaecologist must insert the Cu-IUD, meaning that this is not the preferred method for many users [ 5 ].…”

“…In Germany, it is only used in isolated cases [ 7 ]. Of the oral hormonal methods, the Yuzpe method (oestrogen–progesterone combination comprising two doses of 50 µg ethinylestradiol and 0.25 mg levonorgestrel) is also no longer recommended in Germany for post-coital contraception [ 7 ] because it is less effective than other EC methods and is also associated with more adverse events [ 1 , 6 , 7 ]. Because mifepristone is not available in Germany for this indication [ 7 , 8 ]—unlike some other countries [ 5 , 9 ]—the oral hormonal methods are concentrated on emergency contraceptive pills (or “morning after pills”) containing the active substances levonorgestrel (LNG) and ulipristal acetate (UPA).…”

“…Body weight should be considered in the clinical effectiveness, as body weight alters the effectiveness of emergency contraception with levonorgestrel. Previous studies showed a significant decrease in the effectiveness of levonorgestrel emergency contraception in women with high body weight (16,17).…”

“…Another study in the United States found that 44% of adolescents thought that EC could only be taken within one day of intercourse to be effective [20]. This lack of knowledge extends to providers, with a recent survey in Georgia showing that only 3% of providers knew the maximum window of efficacy for EC [21]. This lack of knowledge is a potential additional barrier for women in Hawaii and future studies should address EC knowledge among women and providers in Hawaii.…”
