The brand marketed as Ovral
in the United States and Canada, for example, contains 50 mcg of ethinyl estradiol and 0.25 mg of levonorgestrel per tablet; therefore, four Ovral
tablets (the dosage Yuzpe and his colleagues used after their original pilot study) constitute the complete regimen.
(*.) The most common brand of oral contraceptive used for emergency contraception in the United States is Ovral
. Lo/Ovral, Nordette, Levlen, and the yellow tablets of Triphasil and Tri-Levlen also may be used in the Yuzpe regimen, but since they contain a lower dosage of hormones, eight tablets are required in total, See: reference 1.
Myers told the eight Catholic hospitals in his diocese that the two drugs, Estinyl and Ovral
, could no longer be used because, he said, they have potential abortifacient capabilities.
