Comments

There are many anecdotal reports of inexplicable or exacerbated depression while taking this drug. In that case, natural progesterone is indicated.

Upjohn claims that the bioavailability of Provera is higher than generic formulations.

The article "Gender Dysphoria Update" by Blaine R. Beemer (originally published in Journal of Psychosocial Nursing and Mental Health Services, 1996: 34(4), 12-19) reports that clients at Vancouver (BC) "routine receive the progestin medroxyprogesterone acetate (Provera)" and asserts that apart "from its effect as an antiandrogen, medroxyprogesterone has been shown to promote bone formation, and may counter the bone loss that might occur with the bllockade of male hormones," citing as a reference: Prior, JC, Vigna, YM, Barr, SI, Rexworthy, C, & Lentle, BC (1994), "Cyclic medroxyprogesterone treatment increases bone density: A controlled trial in active women with menstrual cycle disturbances. American Journal of Medicine, 96, 521-530. A question to consider: does the medroxyprogesterone administration have to be cyclic to have the bone density effect?
