The first combined oral contraceptives contained a high dose of estrogen, with 50 mcg being a common dosage for ethinyl estradiol. A formulation combining ethinyl estradiol 50 mcg and levonorgestrel 0.25 mg is a high-dose contraceptive pill used historically for birth control and certain hormonal conditions. However, this specific dosage is not typically prescribed today due to the widespread availability of safer, lower-dose alternatives.
