Additional Information:

For usage in trans women as a hormone replacement, it should be known that there are no long term studies on the effects of estrogen in those male assigned at birth. Additionally, no studies have been done regarding long term usage of high dosages of estrogen (both synthetic and natural estrogen sources) such as those prescribed for use by trans women.

Note that none of this information applies to plant based estrogens (phytoestrogens).

Several major studies show conflicting data on whether or not estrogen increases or decreases heart disease and related health issues. If you know you have any personal or family history of heart disease you should consult your doctor to ensure that they properly monitor you, and so you can be better educated about your own risks.

While not a psychiatric medication, estradiol valerate and other estrogens, as well as other hormones including progestins and testosterone may have a powerful effect on your mood and mental health. If you have existing mental health conditions or take any psychiatric medications, please consult your prescribing psychiatrist and keep them informed.
