Methylestradiol, sold under the brand names Ginecosid, Ginecoside, Mediol, and Renodiol, is an estrogen medication which is used in the treatment of menopausal symptoms.[2][3][4] It is formulated in combination with normethandrone, a progestin and androgen/anabolic steroid medication.[3][4] Methylestradiol is taken by mouth.[1]

Side effects of methylestradiol include nausea, breast tension, edema, and breakthrough bleeding among others.[5] It is an estrogen, or an agonist of the estrogen receptors, the biological target of estrogens like estradiol.[6]

Methylestradiol is or has been marketed in Brazil, Venezuela, and Indonesia.[3] In addition to its use as a medication, methylestradiol has been studied for use as a radiopharmaceutical for the estrogen receptor.[7]
