A variety of emergency contraception methods have been described, including the following:

  • Emergency contraceptive pills (ECP) (eg, Plan B One-Step OTC, an enteric-coated levonorgestrel ECP that dissolves and is absorbed in the intestine), ovulation inhibition effective until the LH surge.

  • Ulipristal acetate (eg, Ella), available by prescription, progesterone-receptor modulator effective in ovulation inhibition through the LH surge.

  • Copper T380 IUD, foreign body effect creates toxic milieu preventing implantation, not effective for emergency contraception after implantation has occurred.

  • Progesterone agonist/antagonist
