Trimegestone, sold under the brand names Ondeva and Totelle among others, is a progestin medication which is used in menopausal hormone therapy and in the prevention of postmenopausal osteoporosis.[4][2][3] It was also under development for use in birth control pills to prevent pregnancy, but ultimately was not marketed for this purpose.[5] The medication is available alone or in combination with an estrogen.[6][7] It is taken by mouth.[2]

Side effects of trimegestone include headache, breast tenderness, nervousness, abdominal pain, bloating, muscle cramps, nausea, depression, and vaginal bleeding among others.[8][4] Trimegestone is a progestin, or a synthetic progestogen, and hence is an agonist of the progesterone receptor, the biological target of progestogens like progesterone.[2][4] It has weak antiandrogenic and antimineralocorticoid activity and no other important hormonal activity.[2][4]

Trimegestone was first described in 1979 and was introduced for medical use in 2001.[9][10][11] It is sometimes described as a "fourth-generation" progestin.[12][13] The medication is marketed throughout Europe and Latin America.[14][6] It is not available in the United States or Canada.[15][14][6]
